Recent Research: Dong Quai

According to NIH website, Dong quai (Angelica sinensis) is a plant that has been used for a variety of conditions, with little evidence. It may be unsafe when too much is consumed. Dong quai is a member of the same plant family as parsley, celery, and carrots. It's popular in Chinese medicine for female health concerns. The root might affect estrogen and other hormones. People commonly use dong quai for menopausal symptoms, menstrual cramps, migraine, and many other conditions, but there is no good scientific evidence to support these uses. Common side effects include burping, gas, and high blood pressure. (1)

RECENT RESEARCH

Xiaodong Zhi and colleagues consider that fibrosis-related diseases (FRD) include conditions like myocardial fibrosis, pulmonary fibrosis, hepatic fibrosis, renal fibrosis, and others. While, Angelica sinensis may have anti-fibrosis properties in recent investigations. They conducted a thorough literature review, and they concluded that Dong Quai's constituents demonstrated significant anti-fibrosis activity. (2)

Astragalus and Dong Quai have been known to help with heart scarring (myocardial fibrosis). A study discovered a new way these herbs might be working together. When these herbs are boiled together (decoction), tiny clusters of molecules (called supramolecules) form. Pan Liang and collleagues believe that the way these molecules interact (like a puzzle) is important for their effectiveness. Tests showed that these supramolecules were successful in improving heart function and reducing scarring in lab studies and animals.This suggests that these supramolecules might be the key to how the traditional Astragalus-Angelica decoction works. (3) In a seperate study, Xiaolong Song and colleagues conducted a study aimed at the effect of Dong Quai polysaccharide (ASP) extracted from the Lixinshui prescription on cardiac disease induced by hypertension in rats. They concluded that ASP could prevent hypertensive heart disease by inhibiting myocardial fibrosis, suppressing the myocardial apoptosis, and alleviating oxidative stress. (4)

Valentina Trimarco and colleagues designed a study to measure the beneficial effects of a combination of nutraceutics (NUT) containing soy isoflavones (80 mg), dry extract of Angelica sinensis (50 mg), dry extract of Morus alba leaf (200 mg) and magnesium (56.25 mg) in the relief of somatic, psychological, and urogenital symptoms in postmenopausal patients,  The study involved a total of 43 symptomatic postmenopausal women. After a 2-week run-in period, patients were randomized into two arms. One arm received probiotics plus placebo over 4 weeks, followed by a 4-week treatment with probiotics plus NUT. The second arm received probiotics plus NUT for 4 weeks, followed by a 4-week treatment with probiotics plus placebo.  After the NUT period, participants showed a significant reduction in MRS score in comparison to baseline and the placebo period. They concluded that the NUT combination was good for menopause symptoms in postmenopausal patients. (5)

Recent Research: Chamomile

Chamomile (German chamomile, Matricaria recutita, Chamomilla recutita) have two types: German chamomile and Roman chamomile. This fact sheet focuses on German chamomile. Chamomile was described in ancient medical writings and was an important medicinal herb in ancient Egypt, Greece, and Rome. Today, chamomile is promoted for sleeplessness, anxiety, and gastrointestinal conditions such as upset stomach, gas, and diarrhea. It is also used topically for skin conditions and for mouth sores resulting from cancer treatment. (1) Aflatoxin (AFB) is a poisonous mold that can grow on some foods and animal feed. It can make rabbits sick. Mahmoud Gamal Rashad and colleagues investigated if chamomile could improve rabbits' health and protect their livers from damage caused by AFB. In the study, rabbits were divided into four groups: 1. Chamomile group (chamomile): Given chamomile daily, 2. Mold group (AF): Given AFB daily, 3. Chamomile + Mold group (AFLCha): Given both chamomile and AFB daily, and 4. Regular group (CON): Not given chamomile or AFB. They found: Rabbits with AFB grew slower and had smaller bodies compared to those with chamomile or both. Chamomile and the chamomile + AFB groups had healthier livers and kidneys than the AFB group alone. Chamomile and the chamomile + AFB groups had stronger defenses against cell damage than the AFB group alone. The AFB group had more cell damage and weaker defenses than the chamomile and regular groups. In short, this study suggests that chamomile might help protect rabbits from the harmful effects of AFB on their livers. (2) Gastric Cancer is a prevalent malignancy worldwide. While, apigenin (Api), a natural flavonoid found in chamomile tea and some other plant-products. Api may have anti-inflammatory, antioxidant, and antiproliferative properties. With respect to gastric cancer, studies have systematically examined Api’s effects on cancer cells, focusing on cell proliferation, apoptosis, Helicobacter pylori (H. pylori) infection, and molecular targets. The literature suggests that Api inhibits cell growth in a dose- and time-dependent manner Mechanistically, Api acts through the Akt/Bad/Bcl2/Bax axis, activating the mitochondrial pathway of apoptosis and thereby restricting cell proliferation. Though it seems that the anti-proliferative potential of Api on gastric cancer cells is particularly relevant in a more aggressive gastric cancer phenotype but can also affect normal gastric cells. (3) Farshid Bahrami and colleagues conducted a parallel-group randomized controlled design of 3 groups - the damask rose group (n = 30), the chamomile group (n = 30), and the control group (n = 30). In the damask rose and chamomile groups, three drops of 40% essential of each plant were used for inhalation aromatherapy (three drops every hour for 3 hours) The subjects are emergency orthopedic surgery patients. They found that both of the intervention groups experienced a decrease in pain and anxiety over time compared to the control group. (4) REFERENCE 1.

Recent Research: Black Cohosh

Black cohosh (Actaea racemosa or Cimicifuga racemosa, snakeroot, black bugbane, rattleweed, macrotys, and rheumatism weed), a member of the buttercup family, is a perennial plant native to North America. Black cohosh is most likely used for menopausal symptoms, including hot flashes (also called hot flushes) and night sweats, vaginal dryness, heart palpitations, tinnitus, vertigo, sleep disturbances, nervousness, and irritability[1].

RECENT RESEARCH

There is a report that a 76-year-old postmenopausal woman who has been taking Black Cohosh for years has had syncopal attacks multiple times during the past years associated with bradycardia with the heart rate dropping to 30 beats/minute. Discontinuation of Black Cohosh resulted in a gradual resolution of bradycardia, suggesting a plausible association.(2)

Ryoichi Sadahiro and colleagues conducted a meta-analysis of randomized controlled trials conducted to investigate the treatment effect on menopausal symptoms by Black Cohosh extract both alone or combined with other related active ingredients. They reviewed 22 articles of 2,310 menopausal women, and concluded that "black cohosh extracts were associated with significant improvements in overall menopausal symptoms." However, black cohosh did not improve anxiety significantly. (3)

Recent Reseach: Acai

Acai (acai, acai berry, açaí, Euterpe oleracea, Euterpe badiocarpa) palm tree, native to tropical Central and South America, produces a deep purple fruit. The acai fruit has long been an important food source for indigenous peoples of the Amazon region. Acai products have become popular in the United States, where they have been promoted for weight-loss and anti-aging purposes. And here, we review a few articles on Acai.

RECENT RESEARCH

Sérgio Scherrer Thomasi and colleagues conducted analysis of açai berry pulp extracts with LC-UV-BPSU and LC-UV-SPE/NMR. Those techniques identified 23 metabolites: Valine (1), citric acid (2), tachioside (3), isotachioside (4), α-guaiacylglycerol (5), syringylglycerol (6), uridine (7), adenosine (8), dimethoxy-1,4-benzoquinone (9), koaburaside (10), protocatechuic acid (11), eurycorymboside B (12), 7',8'-dihydroxy-dihydrodehydroconiferyl alcohol-9-O-β-D-glucopyranoside (13), orientin (14), homoorientin (15), dihydrokaempferol-3-glucoside (16), isolariciresinol-9'-O-β-D-glucopyranoside (17), 5'-methoxyisolariciresinol-9'-O-β-D-glucopyranoside (18), cyanidin-3-O-glucoside (19), cyandin-3-O-rutenoside (20), 9,12-octadecadienoic acid (Z,Z)-2-hydroxy-1-(hydroxymethyl) ethyl ester (21), linolenic acid (22), and 1,2-di-O-α-linolenoyl-3-O-β-D-galactopyranosyl-sn-glycerol (23). (Reference 2)

There is limited reference for its application on weight-loss and weight management. While a few research articles were found on its "anti-aging" application mainly on animals. One study tested its effects in mice and found it improved mood and protected brain cells, offering similar benefits to existing antidepressants but with potentially fewer side effects.  The juice may also have anti-aging properties by helping maintain healthy brain cells. (Reference 3)

In another study, açai extract was found to be able to strongly protect cells from oxidative stress. Mass spectrometry analyses of HPLC fractionated extract led the researchers to the identification of malvidin and cyanidin derivatives as the most active molecules able to counteract the negative effects induced by UV-A irradiation. (Reference 4)

Very little research has been done in people on the health effects of acai products. More studies are needed to understand how it works exactly.

Recent Research: Aloe Vera

Aloe is a cactus-like plant that grows in hot, dry climates. It is cultivated in subtropical regions around the world, such as the southern border areas of Texas, New Mexico, Arizona, and California. Aloe has been used for skin conditions and was thought to improve baldness and promote wound healing. Topical use of aloe is promoted for acne, lichen planus (a very itchy rash on the skin or in the mouth), oral submucous fibrosis, burning mouth syndrome, burns, and radiation-induced skin toxicity. Oral use of aloe is promoted for weight loss, diabetes, hepatitis, and inflammatory bowel disease. (1) However, extensive studies are needed to confirm the claims.

RECENT RESEARCH

In a stroke, the blood flow to the brain gets blocked, brain cells may die. Microglia are like tiny caretakers in the brain. They can help clean up damage and promote healing, but sometimes they can also worsen the injury. In a study, Xun Li and colleagues focused on a specific way microglia can damage brain cells, called pyroptosis. On the other hand, aloe-emodin is a natural compound found in aloe vera. It belongs to a class of chemicals called anthraquinones, which are known for their laxative effects. Researchers wanted to see if aloe-emodin could help protect the brain after a stroke by influencing microglia. They created mini-strokes in the lab using special techniques. They gave aloe-emodin to some of the cells and looked at how the microglia reacted. They then measured brain function, cell death, and microglia activity. They found, aloe-emodin improved brain function and reduced damage after a stroke. It also seemed to calm down the microglia and prevent them from harming other brain cells. This calming effect may be due to aloe-emodin's influence on a specific pathway inside the microglia. This study suggests that aloe-emodin has potential to be a future treatment for stroke. But lots more research are needed to confirm its effects. (2)

Radiation therapy for breast cancer can irritate the skin, causing redness, dryness, and discomfort (radiation dermatitis). A study compared a new cream (Alantel®) made from natural products to a regular moisturizer to see if it could help prevent this irritation. This was a controlled experiment with two groups: One group used Alantel® cream. The other group used a regular moisturizer. Neither the patients nor the doctors knew which cream each person was using (double-blind). Totally, 70 women with breast cancer undergoing radiation therapy participated. The group using Alantel® was found to have fewer cases of skin irritation compared to the moisturizer group after 4 weeks. The Alantel® group also reported less difficulty with daily activities due to skin problems.This study suggests that Alantel® cream may be effective in reducing skin irritation caused by radiation therapy for breast cancer. More research is needed, but this is a promising finding for women undergoing radiation treatment. (3)

It is known that burn injuries cause severe pain, infection risks, psychological distress, financial burdens, and mortality, necessitating effective care. Aloe vera was reported to show wound healing potential. A study aimed to investigate aloe vera's impact on wound healing, pain management, and infection prevention in burn patients. Yu-Ning Huang and colleagues ran a systematic search on PubMed, Embase, and CENTRAL was performed on 9th October 2023 for randomized controlled trials (RCTs). They found: Aloe vera significantly reduced mean wound healing time compared to other topicals, there was no significant differences in pain reduction and wound infection risk between aloe vera and control groups. Thus, they concluded that aloe vera expedites wound healing in second-degree burn patients without increased infection risk compared to other antimicrobial agents. However, the analgesic effects on burn injuries remain uncertain.

Recent Research: Bilberry

The bilberry bush (Vaccinium myrtillus, Bilberry, European Blueberry, Whortleberry, Huckleberry) is native to northern areas of Europe and Asia, the northern United States, and Canada. Its dark berries resemble blueberries. Since Middle Ages, the berries and leaves of bilberry has been used for medicinal purposes. (1) 

Historically, bilberry has been used for different conditions, such as diarrhea, inflammation of the mouth, urinary problems, diabetes and the prevention of scurvy. It may also improve night vision, and used as dietary supplement for night vision, cataracts, varicose veins, artherosclerosis and some other conditions. For low doses, bilberry may be safe for short term use, however, bilberry may interact with a cancer drug called erlotinib (Tarceval), antidiabetes drugs, or medications that slow blood clotting. (1) Below is a summary of recent research on bilberry. 

RECENT RESEARCH

Bilberry might also be helpful for people with presbyopia and dry eyes. There is based on a small initial study. Presbyopia is a common eye condition that makes it harder to see things close up, affecting many people over 50. Dry eyes are another issue that can cause discomfort. The study looked at a combination of these three berries, finding that after 6 weeks, most people saw some improvement in their near vision. There was also an initial improvement in dry eye symptoms, but this lessened over time. It's important to note that this is a very early study and more research is needed to confirm these findings. However, it suggests bilberry might be a natural approach to help with presbyopia and dry eyes. (2)

On the other hand, a small study examined if a combination of bilberry and grape seed extract could improve health markers in people at risk of type 2 diabetes. While it didn't affect blood sugar or cholesterol, it did show a decrease in blood pressure for some participants. Interestingly, those who responded well to the supplement had different gut bacteria compared to those who didn't. This suggests bilberry might be helpful for blood pressure control in some people, but more research is needed to understand exactly who might benefit most. (3)

Review / Recent Research: 5-hydroxytryptophan (5-HTP)

5-hydroxytryptophan (5-HTP) is a chemical byproduct of the protein building block L-tryptophan. It is produced commercially from the seeds of an African plant known as Griffonia simplicifolia. 5-HTP can be converted to serotonin in the body. It works in the brain and central nervous system by increasing the production of serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Since 5-HTP increases serotonin levels, it is used for conditions in which serotonin is believed to play an important role. These possibly include depression, anxiety, and many other conditions. However, it may be ineffective for improving muscle strength or development in children with Down syndrome. (1) 

According to the reference 1, it is possibly safe to take 5-HTP by mouth in doses of up to 400 mg daily for up to one year. The most common side effects include heartburn, stomach pain, nausea, vomiting, diarrhea, drowsiness, sexual problems, and muscle problems. Large doses of 5-HTP, such as 6-10 grams daily, are possibly unsafe. These doses have been linked to severe stomach problems and muscle spasms. And, some people who have taken 5-HTP have developed a serious health condition called eosinophilia-myalgia syndrome (EMS). (1)

RECENT RESEARCH

Clarinda Nataria Sutanto and colleagues studied whether a daily supplement of 5-HTP, a natural precursor to sleep hormones, could improve sleep in older adults. They divided 30 people over 65 into two groups, one taking 5-HTP and the other not. After 12 weeks, they found that people who already had trouble sleeping benefited the most from the supplement, reporting better sleep quality. Interestingly, the supplement also seemed to improve the gut bacteria of those who had poor sleep initially. Overall, this small study suggests that 5-HTP might be a helpful option for older adults with sleep problems. (2)

Researchers studied how a common chemotherapy drug (doxorubicin) damages the heart and found a way to potentially prevent this damage. The drug works well against cancer, but it weakens the heart muscle over time. They discovered that the drug disrupts communication between heart cells, leading to a weaker heart structure. They then found that a substance the body naturally produces (5-HTP) can block this communication disruption and protect the heart from the chemotherapy drug's harmful effects. Importantly, this protection doesn't prevent the drug from working against cancer. This research suggests that 5-HTP might be a future medicine to help people undergoing this type of chemotherapy avoid heart damage. {3}

Review: Ashwagandha

Ashwagandha (Withania somifera (L.); Indian ginseng; winter cherry) is an evergreen shrub cultivated in tropical and subtropical areas of Asia, Africa, and Europe. its roots are said to smell like a wet horse. Ashwagandha has been used in the traditional Ayurvedic and Unani medicine systems as an adaptogen, which is considered as a substance that increases the a person's ability to resist, adapt, or become resilient in nonspecific ways to biological, physical, or chemical stressors. Ashwagandha may induce sleeping, and it is commonly promoted for stress and anxiety reduction and for cognitive disorders. Ashwagandha has lots of phytochemicals, such as withanolides and alkaloids. Withanolides are believed to contribute lots of ashwagandha’s beneficial effects. However, evidence suggests that other compounds may also be involved.

POTENTIAL HEALTH BENEFITS

A 2021 systematic review identified seven studies investigating ashwagandha to treat stress and anxiety. Overall, the they found that ashwagandha significantly reduced stress and anxiety levels, reduced sleeplessness and fatigue, and reduced serum cortisol levels, compared with placebo. In several studies, benefits appeared to be greater with doses of 500 to 600 mg/day compared with lower doses. Results from three additional sstudies published after this 2021 review also suggest that ashwagandha has a beneficial impact on perceived stress. Another study of ashwagandha extract in India also showed an effect of lowering serum cortisol levels. In a double-blind trial, an extract containing 2.5 mg of withanolides per 350 mg capsule, dose of twice a day, showed increased well-being including a sense of calm, improved energy levels, heightened mental clarity, and enhanced sleep quality. 

One study of 150 healthy men and women with self-reported sleep problems showed ashwagandha extracts helped with subjects in sleep quality such as total sleep time, sleep latency (time taken to fall asleep), and awakening after sleep onset. Another study of 80 healthy men and women and 5 other studies also showed the sleep-improvement effect of ashwagandha. 

POTENTIAL SIDE EFFECTS

In the studies described above and in many other clinical trials, ashwagandha has been well tolerated by subjects for up to about 3 months of use. Common side effects are mild and include stomach upset, loose stools, nausea, and drowsiness. There aer also few cases of serious side effects related to liver functions, thyroid functions or even abortion. Anyway, ashwagandha appears to be well tolerated for up to 3 months of use. Users should watch if there are any possible side effects, and discuss with a medical doctor before starting any supplements.

Quick View: Ayurvedic Herbs

Ayurvedic herbs are plants and plant parts used in traditional Indian medicine, Ayurveda.  Ayurveda is a holistic system of medicine that has been practiced in India for thousands of years. It emphasizes the balance between the mind, body, and spirit. Ayurvedic herbs are thought to promote health and well-being by balancing the body's three doshas, or energies: vata, pitta, and kapha.

Here is a list of popular Ayurvedic herbs:

Ashwagandha (Withania somnifera): An adaptogenic herb that is used to reduce stress and anxiety, improve sleep, and boost energy levels.

Turmeric (Curcuma longa): A well-known anti-inflammatory herb that is used to treat a variety of conditions, including arthritis, pain, and digestive disorders.

Triphala: A blend of three fruits (amalaki, bibhitaki, and haritaki) that is used to improve digestion and elimination.

Brahmi (Bacopa monnieri): An herb that is used to improve memory and cognitive function.

Gotu kola (Centella asiatica): An herb that is used to improve circulation, wound healing, and cognitive function.

Amla (Emblica officinalis): A fruit that is rich in vitamin C and antioxidants. It is used to boost the immune system. 

It is important to note that Ayurvedic herbs are not a regulated medical product in the United States.  This means that the safety and efficacy of these herbs have not been rigorously studied.  It is always best to speak with a qualified healthcare professional before using any Ayurvedic herb.

Recent Research: Melatonin

In a review article, Esther M Speksnijder and colleagues state that using hormones such as adrenal glucocorticoids and melatonin and the autonomic nervous system, the SCN modulates critical processes such as glucose production and insulin sensitivity. (1) Thus, it is interesting to understand how melatonin acts on glucose homeostasis or related issues.

According to the research titled “Melatonin Improves Glucose Homeostasis and Insulin Sensitivity by Mitigating Inflammation and Activating AMPK Signaling in a Mouse Model of Sleep Fragmentation,” melatonin appears to play a crucial role in glucose homeostasis and metabolic health. Here are the key findings from the study conducted by Seok Hyun Hong and colleagues:

Sleep Fragmentation (SF) and Metabolic Dysfunction:

Sleep fragmentation, characterized by disrupted sleep patterns, can lead to inflammation and increased production of reactive oxygen species (ROS). Sleep Fragmentation is associated with inflammation in adipose tissue and insulin resistance.

Melatonin’s Potential Beneficial Effects:

Previous studies have suggested that melatonin might have metabolic benefits due to its ability to activate AMP-activated protein kinase (AMPK). AMPK is a key cellular energy-sensing complex that plays a role in maintaining metabolic homeostasis.

The Experiment:

The researchers conducted an experiment using adult male C57BL/6 mice. The mice were divided into three groups: Control group (no SF), SF group (housed in SF chambers), SF+Mel group (SF mice with daily oral melatonin treatment) After 12 weeks, various assessments were performed, including glucose tolerance tests, insulin tolerance tests, and AMPK assessments.

Results:

SF mice showed increased weight gain, impaired glucose regulation, inflammation, and decreased AMPK expression in white adipose tissue (WAT) compared to the controls. Melatonin treatment significantly improved these outcomes by mitigating SF-induced metabolic dysfunction, inflammation, and AMPK downregulation in adipose tissue.

Therapeutic Efficacy of Melatonin:

The study suggests that melatonin’s ability to restore adipose tissue homeostatic pathways may contribute to its therapeutic efficacy against cardiometabolic impairments induced by SF. In summary, melatonin appears to positively impact glucose homeostasis by restoring AMPK expression and related pathways in adipose tissue. Its potential as a therapeutic agent for metabolic dysfunction warrants further investigation.

Recent Research; Turmeric

Turmeric is a spice that contains curcumin, a compound with anti-inflammatory and antioxidant properties. Turmeric supplements may help with arthritis pain and inflammation. Here, we are going to review a few articles on this topic:

Vishnu Mittal and colleagues have published an article on herbal interventions in rheumatoid arthritis treatment. The article suggests turmeric may be helpful in managing Rheumatoid Arthritis symptoms. The review highlights turmeric's anti-inflammatory and antioxidant properties, which might be crucial in alleviating Rheumatoid Arthritis symptoms. Turmeric may work by modulating inflammatory pathways, potentially reducing inflammation in the joints – a hallmark of Rheumatoid Arthritis. While the evidence is promising, more rigorous clinical trials are needed to confirm how effective and safe turmeric is for Rheumatoid Arthritis. (1)

While, Carla Gasbarri and Guido Angelini focus more on the active ingredients of tumeric. They state that curcumin is the main active ingredient in turmeric and is often credited with its health benefits.However, turmeric also contains another natural compound called cyclocurcumin. Although they have the same chemical formula, they behave differently. Curcumin can change its structure slightly depending on the environment, while cyclocurcumin can change shape. While curcumin gets most of the attention for its potential health benefits, cyclocurcumin is also interesting to scientists because it may act as an antioxidant, fight enzymes, and even combat viruses. Early research suggests it might be useful for treating degenerative diseases and heart problems. However, despite its potential, cyclocurcumin's use in medicine is limited because it's difficult for the body to absorb. (2)

Tingting Deng and co-workers consider that "Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by synovial inflammation, cartilage destruction, pannus formation and bone erosion. Various immune cells, including macrophages, are involved in RA pathogenesis." They are looking at curcumin as a potential treatment for rheumatoid arthritis (RA). RA is an autoimmune disease that causes inflammation and damage to joints. Part of the problem is that immune system cells called macrophages become unbalanced. These macrophages can either be helpful (M2) or harmful (M1) in RA. Curcumin seems to work by tipping the balance towards the helpful M2 macrophages, which might reduce inflammation and joint damage in RA. However, more research is needed to fully understand how effective curcumin might be. (3)

Recent Research: CoQ10

Injuries are important medical problems that may cause inflammation, oxidative stress, endocrine disorders, immune response, and hypermetabolic and catabolic responses which affect most organs in the body. Research has shown that CoQ10 may help subjects from certain injuries. Here, we are going to review a few articles on this topic:

Gulce Gel and colleagues investigated whether combining Coenzyme Q10 (CoQ10) and ozone therapy could help rats recover from spinal cord injuries. The study found that rats given both treatments showed better results than those given either treatment alone. This suggests a combined approach might offer neuroprotective benefits by reducing cell death and improving overall recovery based on various assessments.

Soleyman Bafadam and colleagues, on the other hand, studied a potential treatment for heart damage in older rats. When blood flow to the heart is blocked and then restored (reperfusion), it can cause further damage. Researchers examined if combining two treatments, mitochondrial transplantation (injecting healthy energy centers from cells) and CoQ10 (a coenzyme), could protect the heart muscle. They found that the combination improved heart function and reduced cell death compared to either treatment alone. This suggests that combining these approaches might be a promising strategy to protect the heart from damage caused by reperfusion injury, especially in older individuals.

Zahra Kiani and colleagues investigated whether CoQ10 supplements could help patients recover from burn injuries. The study found no significant improvements in inflammation, oxidative stress, or other key recovery markers. However, patients taking CoQ10 did show an increase in albumin, a protein important for various bodily functions. More research is needed to confirm this effect and understand its potential benefits.

Recent Research: Probiotics

Probiotic administration is a promising therapy for improving conditions in non-alcoholic fatty liver disease patients and potentially some other types of conditions. Here, we are going to review a few articles recently published on this topic:

Ehsan Amini-Salehi and colleagues conducted a study to investigate how improving gut bacteria with probiotics, prebiotics, and synbiotics affects body measurements in people with non-alcoholic fatty liver disease. (1)

Studies suggest these gut health supplements might benefit non-alcoholic fatty liver disease patients, but the exact effects are unclear. Thus, Ehsan Amini-Salehi and colleagues reviewed studies published up to June 2023 that looked at the effects of these supplements on body measurements (BMI, weight, waist circumference, waist-to-hip ratio) in non-alcoholic fatty liver disease patients.They found, Body Mass Index (BMI) significantly decreased with gut microbiota modulation. Weight and waist circumference did not change significantly, although there was a trend towards decrease in weight. They reported that probiotics seemed to have the strongest effect on lowering BMI, followed by prebiotics and synbiotics.However, there wasn't enough data on waist-to-hip ratio or waist-to-height ratio. They concluded that modulating gut bacteria with these supplements may help reduce BMI in non-alcoholic fatty liver disease patients, but more research is needed to confirm effects on other body measurements. (1)

Yafang Yang and colleagues also ran a similar study. They analyzed multiple studies on probiotics for non-alcoholic fatty liver disease and found that a combination of Lactobacillus, Bifidobacterium, and Streptococcus bacteria appears to be most effective. This specific combination showed the greatest potential for improving liver enzyme levels, blood fat levels, and reducing inflammation markers, compared to other single or combined strains of probiotics. These results provide valuable insights for developing future treatment guidelines using probiotics for non-alcoholic fatty liver disease. (2)

Probiotics may offer additional benefits following Roux-en-Y gastric bypass surgery. A study conducted by Hamid Melali and colleagues found that while both groups lost weight after surgery, those taking probiotics had better blood sugar control (lower fasting blood sugar and HbA1c), higher vitamin B12 levels, and improved gut health (based on GI symptoms) compared to those taking a placebo. (3)

Review: Sucralose

Sucralose (trichlorogalactosucrose, a unique disaccharide, a key ingredient of Splenda) is an artificial sweetener from native sucrose that was approved by the FDA on April 1, 1998 (April Fool's Day). Popular brand name of sucralose-based sweetener is Splenda. Sucralose is relatively safe for diabetes, as it does not alter insulin levels and does not carry calories.

According to Wikipedia.com, some adverse side effects were seen at doses that significantly exceeded the estimated daily intake (EDI), which is 1.1 mg/kg/day. About 11-27% of sucralose is absorbed.

Sucralose Side Effects

Patel RM and co-workers from Mercer University School of Medicine, Macon, GA, ported a potential association between sucralose and migraines. [1] Bigal ME and Krymchantowski AV from The Albert Einstein College of Medicine. NY, reported a patient with attacks of migraine consistently triggered by sucralose. She also suffers from menstrually related migraine that had been well-controlled for several months since she switched her contraceptive from fixed estrogen to triphasic contraceptive pills. Some attacks triggered by sucralose were preceded by aura, and she had never experienced migraine with aura before. Withdrawal of the compound was associated with complete resolution of the attacks. [2]

Goldsmith LA from McNeil Specialty Products Company published a paper titled, "Acute and subchronic toxicity of sucralose" in Food Chem Toxicol. in 2000 and he claimed that he observed no toxicologically significant effects at the 1.0% or 2.5% dietary levels of sucralose for 4 and 8 weeks in male and female mice. [4] 

Now the questions are: What happens if an animal takes it daily for a year or longer? What would be the sucralose side effect, if any?

A 52 week-study of rats showed that sucralose was not carcinogenic. Sucralose did not adversely affect the survival or clinical condition of the rats, and there were no toxicologically significant findings. However, adverse side effects were noticed in the sucralose treated female groups especially at higher doses. The adverse findings included renal pelvic epithelial hyperplasia, renal pelvic mineralization and adrenal cortical haemorrhagic degeneration. While, cataracts were found in male rats at high doses. [3] If this is applicable to human, we should not overdose ourselves with sucralose. 

According to Medicinenet.com [l], sucralose side effects include bloating, gas, diarrhea, nausea, skin irritations, wheezing, cough, runny nose, chest pains, palpitations, anxiety, anger, moods swings, depression, and itchy eyes. Further, surcralose may interfere drug absorption and microorganism populations in our gut.

Review: Astaxanthin

Astaxanthin is a natural pigment found in microalgae, some types of seafood (like salmon). Studies suggest astaxanthin might improve blood flow and reduce inflammation, but more research is needed to confirm these effects and understand how they might translate into improved health outcomes.

Safety Studies on Astaxanthin: A Simpler Explanation

Here's a breakdown of what scientists have found about the safety of astaxanthin in studies on animals and humans:

Animal Studies:

  • Scientists fed rats increasing amounts of astaxanthin for 90 days. Even at the highest dose, the rats showed no major weight changes, blood problems, or other harmful effects. However, at this high dose, some changes were seen in the kidneys, but they weren't considered serious. (1)

Human Studies:

  • A study looked at healthy adults taking astaxanthin supplements for 8 weeks. There were no significant differences between those taking astaxanthin and those taking a placebo (dummy pill), except for very minor changes in some blood test results that weren't medically important. This suggests astaxanthin at this dose (6mg daily) is safe for healthy adults. (2)
  • Another study examined the effects of astaxanthin on blood flow in men. They found a slight improvement in blood flow after 10 days of taking astaxanthin (6mg daily) compared to a placebo. Again, no safety concerns were identified. (3)

Additional Information:

  • Studies also showed that astaxanthin gets stored in various organs and tissues, with the highest concentration in the skin (which explains the pink/red color in some animals). This storage seems to be temporary, and the body eliminates astaxanthin relatively quickly. However, potential adverse effects such as lesions in the kidneys of three animals and a slight change in the leucogram were noted. (4)

Key Takeaways:

  • Based on these studies, astaxanthin appears to be safe for consumption at moderate doses (around 6mg daily) in healthy adults.
  • More research is needed to fully understand the long-term effects and any potential benefits of astaxanthin.

Review: Elderberry for Respiratory Illness, COVID-19 Infection.

A review by Dr. Susan Wieland of the University of Maryland School of Medicine and colleagues examined the use of elderberry for preventing and treating viral respiratory illnesses.

Background:

Elderberry has a long history of use for respiratory issues. During the COVID-19 pandemic, interest in elderberry supplements for preventing or treating the illness surged. However, concerns existed regarding elderberry potentially overstimulating the immune system and triggering a cytokine storm (an excessive immune response). Dr. Wieland's team aimed to assess the benefits and potential side effects of elderberry for these purposes.

Methods:

The researchers searched six databases, four research registries, and preprint materials, screening 1187 records. They identified five randomized trials on elderberry for treating or preventing viral respiratory illnesses. They found no studies linking elderberry to clinical inflammation issues, but three studies examined cytokine production after elderberry intake in a lab setting (ex vivo).

Results:

  • The review suggested elderberry might not prevent the common cold but could potentially reduce its duration and severity. Similar findings were seen for influenza, although the evidence for both effects was considered inconclusive. (1)
  • The researchers compared elderberry supplements to oseltamivir (an antiviral medication). They found that elderberry might be associated with a lower risk of influenza complications and side effects. However, evidence regarding elderberry and clinical inflammation outcomes was lacking. Interestingly, some evidence suggested elderberry might influence inflammatory markers, though this effect may diminish with continued use.
  • A small study compared elderberry's effectiveness in reducing cytokines over time to diclofenac (an anti-inflammatory drug). The results suggested elderberry might be equally or slightly less effective than diclofenac. (1,2)

(Note: A brief explanation of cytokines was added for clarity)

Additional Research on Potential COVID-19 Treatments

A separate review by Brett R. Martin and Joshua Richarson examined research articles from 2005 to 2021 on potential treatments for coronavirus infections. They focused on substances with anti-inflammatory, immune-stimulating, or antiviral properties, including vitamin D, zinc, vitamin A, elderberry, garlic, licorice, stinging nettle, N-acetylcysteine, quercetin, and selenium. Their findings suggested these substances might offer some benefit, but only vitamin D, zinc, licorice, quercetin, and selenium had research specifically related to COVID-19 effects. (3)

Review: Linoleic Acid

Linoleic acid (LA) is an unsaturated n-6 fatty acid. It is a colorless liquid at room temperature. In physiological literature, it has a lipid number of 18:2(n-6). Linoleic acid is a polyunsaturated fatty acid used in the biosynthesis of arachidonic acid (AA) and thus some prostaglandins. It is found in the lipids of cell membranes. Thus, a lack of linoleic acid and other n-6 fatty acids in the diet causes dry hair, hair loss, and poor wound healing. However, linoleic acid is abundant in many foods, especially plant oils, thus, a deficiency in linoleic acid is almost impossible. [Wikipedia, 2011]


Epidemiological studies show that Omega-6 polyunsaturated fatty acids (n-6 PUFA) dietary intake significantly lowers blood LDL-cholesterol levels. In addition, n-6 PUFA intake lower several cardiovascular risk factors such as blood pressure, inflammatory markers, haemostatic parameters and obesity. [2] However, a study of 2069 men and women, linoleic acid intake was inversely associated with total cholesterol and HDL-cholesterol in women but not in men. Linoleic acid intake was not associated with the ratio of total to HDL-cholesterol. No association was observed between linoleic acid intake and CHD incidence. [1]

An international cross-sectional epidemiological study of 4680 men and women ages 40 to 59 suggests associations of linoleic acid intake of individuals with their blood pressure. Dietary linoleic acid intake may contribute to prevention and control of adverse blood pressure levels in general populations. [3]

Linoleic acid (LA) is know to induce proliferation and invasion in breast cancer cells. [4] Linoleic acid stimulated growth of the MDA-MB-231 and MCF-7 human breast cancer cell lines in culture. [5]Human MCF-7 breast cancer cells were incubated for 12 d in culture medium supplemented with various concentrations (1.78-7.14 x 10(-5) M) of linoleic acid (LA) or CLA. Linoleic acid initially stimulated MCF-7 cell growth with an optimal effect at concentrations of 3.57-7.14 x 10(-5) M, but was inhibitory at similar concentrations after 8 and 12 d of incubation. [6] Thus, at certain concentrations, linoleic acid is a cancer-enhancer while at certain concentrations, it is an anti-cancer agent.

Five health supplements for menopause

 While there's no one-size-fits-all approach to managing menopause symptoms, certain supplements have shown promise in alleviating specific concerns. Here are 5 well-regarded options to consider, but remember to consult your doctor before starting any new supplement regimen:

  1. Black Cohosh: This herb has been traditionally used for centuries to relieve hot flashes and night sweats, common vasomotor symptoms during menopause. Studies suggest it might be effective, but long-term use can have side effects, so consult your doctor for proper dosage and duration.
  2. Magnesium: This mineral plays a crucial role in various bodily functions, including sleep regulation and muscle relaxation. Magnesium deficiency is linked to worsened sleep and mood swings during menopause. Supplementing with magnesium, particularly glycinate or citrate forms, can improve sleep quality and ease muscle tension.
  3. Vitamin D: Crucial for bone health, vitamin D levels often decline with age, increasing the risk of osteoporosis during menopause. Ensuring adequate vitamin D intake through sun exposure, diet, or supplements can help maintain bone strength and reduce fracture risk.
  4. Omega-3 Fatty Acids: These heart-healthy fats possess anti-inflammatory properties that might benefit cardiovascular health and cognitive function, both of which can be impacted by menopause. Consuming fish rich in omega-3s or taking fish oil supplements can be helpful.
  5. Probiotics: The gut microbiome plays a vital role in overall health, including immune function and mood regulation. Menopause can disrupt the gut microbiome, potentially contributing to certain symptoms. Probiotic supplements can help restore gut balance and potentially alleviate digestive issues, mood swings, and vaginal health concerns.

Remember, these supplements are intended to complement a healthy lifestyle, not replace it. Maintaining a balanced diet, regular exercise, and stress management practices are crucial for managing menopause effectively. Consult your doctor before taking any health supplements.
