495119012This randomized, double-blind placebo-controlled clinical trial was conducted in women between the ages of 40 and 70 who reported menopausal symptoms. Women were evaluated using two conventionally recognized scales of menopause symptoms, the Kupperman Index (KI) and the Menopause Rating Scale (MRS). Women were randomized to receive either placebo or an extract of Schisandra chinensis… with each pill containing 196 mg of natural extract, and 2 pills twice per day. Women received the treatment for 6 weeks, and then were followed for 12 weeks.

Daily diaries, questionnaires and laboratory studies were performed at baseline, 6 weeks and 12 weeks.

The primary endpoint was the average interval change in KI score from baseline to week 12 with secondary outcomes including laboratory studies and the MRS for sexual and bladder problems. Thirty six women completed the study.

Results: In the Schisandra group, the KI score decreased by 21.6% at the 6 week visit and by 41.2% at the 12-week visit. In the placebo group, the KI score decreased by 12.6% at the 6 week visit and 27.2% at the last visit. The specific symptoms for which Schisandra helped were hot flushes, sweating and heart palpitations and the rates of reduction were about 50% from the beginning to the end. The MRS scores for sexual problems and urinary problems revealed no significant differences between the herbal group and the placebo group. Estradiol serum levels were slightly increased in the herbal group, but was not statistically significant compared to placebo.

Commentary: Schisandra chinensis is a berry whose name means “five flavors” in Chinese: salty, sour, bitter, spicy(pungent) and sweet. In traditional Chinese medicine, it has been used for thousands of years for the common cold, kidney diseases and memory improvement. Modern research has investigated it’s use in vascular diseases and Alzheimer’s disease. Schisandra chinensis should be added to the list of botanicals demonstrating some scientific efficacy for menopausal related hot flushes/ night sweats and heart palpitations.

As most of us know, breast cancer is the most common cancer in women, although lung cancer is more deadly. Integrating some aspect of natural medicine has become common place for women with breast cancer… at the very least, nutritional and exercise changes. The inclusion of flax seeds in the diet of breast cancer patients has been one nutritional influence that has been looked at in the research. Flax seed contains high concentrations of α-linolenic acid, ω-3 fatty acid, and a variety of lignans. Flax seeds are a dense source of the lignan secoisolariciresinol.

Several databases, including Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Embase, Embase Classic, and Allied and Complementary Medicine were searched through December 2, 2011. The review included controlled and uncontrolled human studies of women at risk of developing breast cancer or already diagnosed with cancer. The flax seed products included flax seed, flax seed-derived compounds, and flax seed oil. Hot flash occurrence, risk of breast cancer, breast cancer recurrence, breast cancer mortality, tumor characteristics, surrogate markers of breast cancer risk, and changes in hormonally responsive tissues were included as outcomes.

A total of1892 articles were retrieved from the databases and ten studies met the inclusion criteria. Only two of these studies were randomized, controlled trials. In the first study, ground flax seed bars were not found to significantly affect the rate of hot flashes compared to placebo bars in 135 women with breast cancer or a history of breast cancer. The second study measured biopsied breast tissue in 32 women with breast cancer before and after treatment with flax seed cooked into flax seed muffins. In the women who consumed the flax seeds, beneficial findings included an apoptotic index that increased significantly and human epidermal growth factor receptor 2 (HER2)  expression and Ki-67 labeling index, a marker of cell proliferation, both decreased significantly (−71.0% and −34.2%), respectively.

There were two trials without controls. One in which hot flashes decreased significantly with the consumption of 40 g of crushed flax seed per day. The second in which women consumed 50 mg of a lignan found in flax seed, for 12 months. In those with a positive response, there was a significant decrease in Ki-67 and atypical cell morphology of breast tissue.

In a single, nonrandomized, open-label study, biomarkers of angiogenesis in breast tissue were measured. Nine healthy women consumed 25 g flax seed and were compared to 11 patients with breast cancer undergoing tamoxifen treatment (20 mg daily). Flax seed and tamoxifen increased endostatin by approximately 33% in breast tissue, whereas tamoxifen, but not flax seed, decreased the other markers of angiogenesis.

Five observational studies were found. In two of these, consumption of lignans or flax seed (one quarter cup per day of flax seeds) resulted in a 19% or 20% reduction in the risk of developing breast cancer, respectively. The effect of flax seed was significant only in postmenopausal women. In a third observational study, no decrease in breast cancer risk was found with the consumption of a combination of sesame and flax seeds, although the amount was quite low at 1.42 mg/day. In another sesame/flax combination study, no effect on breast cancer mortality was seen, however, women in the study that consumed 0.3 to 3.5 g/day of sesame/flax were found to have a 31% reduction in overall mortality; but no advantage of > 3.6 gm/day. In the last observational study, a significant relationship was found between flax seed oil consumption and better mental health scores, as reported by the women, in women with breast cancer.

Commentary: This data in total, is encouraging in that it suggests that flax seed may decrease the incidence of breast cancer and may alter the growth of tumors through altering angiogenesis… which means limiting the blood supply to tumors. There also appears to be some advantage for postmenopausal women in that they may benefit more from the consumption of flax seed than do premenopausal women. Flax seeds contain phytoestrogen compounds, which some individuals have been concerned about. However, these compounds appear to be protective, especially in a low estrogen environment such as post menopause. There is a large body of scientific evidence that plants containing these phytoestrogen compounds, including three very large studies on soy products in breast cancer patients…may decrease the progression of breast cancer and women who eat soy regularly if not daily…will have a better outcome with their breast cancer. In addition, animal studies have found that flax seed and flax seed extracts reduce cell proliferation, angiogenesis, metastasis, and tumor size, and promote apoptosis.

Menstrual cramps, when due to primary dysmenorrhea, are caused by the action of endometrial prostaglandins and is a normal process of menstruation, to a degree, that then causes the contractions of the uterus. However, for some women, it is more than mild discomfort and can be mild, moderate or severe and depending on the pain level, needs to be treated during those painful days, as well as a strategy to try to reduce the pain for the next menstrual cycles. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most common acute treatment, but can cause peptic ulcers, liver or kidney disorders and allergic reactions. Hormonal contraceptives are also commonly used to manage the chronic nature of the problem. Herbal and nutritional therapies have been shown to reduce acute pain in several published studies and have included valerian, ginger, cinnamon and niacin. High dose Vitamin D before the menstrual cycle and regular select doses of fish oils have been shown to reduce the subsequent painful cycles.

Previous studies have shown that metabolism and absorption of vitamins and minerals may play a role in the etiology of and treatment of menstrual disorders. Lower serum calcium levels have been associated with muscle spasm and contraction. Vitamin D may help to regulate prostaglandins.

The current randomized placebo-controlled trial attempted to determine the effect of combined Calcium-Vitamin D and Calcium alone on the intensity of menstrual pain and menstrual blood loss in women with primary dysmenorrhea. Iranian women aged 18-32 with painful and regular menses in the previous 6 cycles were given either Calcium-Vitamin D tablets of 1,000 mg Calcium carbonate and 5,000 units of Vitamin D, or Calcium carbonate alone 1,000 mg or placebo. Each group took their tablet once daily from day 15 until the end of the menstrual flow, for one cycle.

Compared to placebo, the mean pain intensity was lower in both the Calcium-Vitamin D group (-0.7) and the calcium alone group (-1.6) but was only statistically significant in the calcium alone group. Menstrual blood loss was not significantly different in any of the 3 groups. The mean percent change of pain intensity from baseline was 20% in the Calcium-Vitamin D group, 32% in the calcium alone group and 6% in the placebo group.

Commentary: This study confirms the effectiveness of something as simple as508095722 Calcium 1,000 mg/day starting on day 15 and through the menstrual flow in reducing the severity of primary dysmenorrhea. In an earlier trial, the authors demonstrated that effectiveness of 600 mg/day from day 15 through menses in reducing menstrual pain intensity. Other research has shown that dysmenorrhea was significantly less common in young women who consumed 3 or 4 servings of dairy products every day compared to those who consumed no dairy. Another study showed that women with very severe dysmenorrhea reported lower intake of dairy products. On the other hand, there was a study that reported a positive relationship between consumption of dairy and severity of pain. Despite the one report showing a negative vantage point of dairy products and dysmenorrhea, I would assert that this simple notion of Calcium 1,000 mg/day starting on day 15 is an important option in trying to reduce the impending menstrual cramps.

599254720Heartburn, often called acid indigestion is when there is a burning/acidic sensation in the chest. It is caused by a back up of acid from the stomach into the esophagus and throat. Classic symptoms are those burning sensation behind the sternum and/or in the throat, but can also be accompanied by nausea, belching, bloating. When we have one or more of these symptoms, it may not be a simply case of heartburn, which is a symptom, but rather gastroesophageal reflux disease (GERD), which is a disease that involves chronic acid regurgitation that can damage the lining of the esophagus. If one has at least two episodes of heartburn per week, that is when we need medical advice and perhaps an evaluation for GERD. GERD can also exist without any heartburn/acidic sensation at all…but perhaps a nagging cough, hoarseness, laryngitis, wheezing, postnasal drip, sinusitis, chest/ear or jaw pain, painful swallowing or a sensation in the throat.

There are natural medicine supplements, over the counter pharmaceuticals and prescription medications for heartburn and GERD. What I want to focus on here though, are the basic lifestyle changes that are fundamental to any pill, no matter the nature of the pill.

· WEIGHT-Weight management- excess weight, especially abdominal fat can contribute to heartburn or GER by putting pressure on the stomach which then pushes the contents up into the stomach. Even a gain of 10 # in women can increase the risk by 40%. Once a woman is in the category of overweight or obese, the risk of GERD symptoms doubles or triples. Losing weight can decrease symptoms.

· TIMING OF EATING-Avoid eating for 2-3 hours before bedtime. This allows time for the stomach to empty. Even before going to bed, avoid lying down after eating and avoid exercising right after eating.

· SMALLER MEALS; REDUCE FLUIDS WITH MEALS-Larger meals puts greater pressure on the lower sphincter of the stomach which then leads to a greater likelihood of back up into the esophagus.

· STOP SMOKING- Smokers have an increased risk for acid reflux due to possible relaxing effects of the smoking on the sphincter. Smoking also decreases salivary production and with less saliva, we miss out on some neutralization of acid in the stomach.

· AVOID SELECT FOODS and BEVERAGES- Spicy, fatty foods, fried foods, citrus fruits and beverages, alcohol, chocolate, milk, peppermint, coffee, tea, carbonated beverages and milk. Some relax the sphincter, some are acidic and some actually promote acid production.

· ELEVATE THE HEAD OF YOUR BED-for those who have symptoms at night or early in the morning, putting wooden blocks under the headboard to raise it 4-8 inches can help to prevent reflux. Another option is to use a foam bed wedge which elevates the upper part of the body.

· SLEEP ON LEFT SIDE- believe it or not… this could help… Our stomach bends to the left… so when you lie on the left side, a portion of the stomach is lower than the esophagus… which may help to reduce backup of food and acid into the esophagus. Every little bit can help.

· SUGARLESS GUM-chewing gum after meals can stimulate saliva production which then helps to neutralize stomach acid and soothe the lining of the esophagus. I would also mention here to choose gum wisely in terms of healthier choices for the gums and teeth. One example includes those made with xylitol.

· CHECK MEDICATIONS-some medications can actually cause or contribute to heartburn or acid reflux. Your doctor and pharmacist can be very helpful here. Possible suspects include bisphosphonates, aspirin, ibuprofen, benzodiazepines, opioid narcotics, calcium channel blockers, potassium, progestins, certain antihistamines and antispasmodics, and even peppermint based herbal products.

· AVOID TIGHT CLOTHES-tight pants at the waist, tight girdles and belts can put pressure on the stomach and can worsen reflux.

· BEND AT THE KNEES- there are many reasons to bend at the knees when lifting or picking up items from the floor due to low back care in particular… but for those individuals who may do this repetitively due to their job or activities of daily living… this may also put pressure on the stomach.

That’s it for now, in terms of lifestyle changes that serve as the basic foundation upon which to add select nutritional/botanical supplements that address both cause and provide symptom relief or over the counter or prescription medications if needed.

488559207Did you know that curcumin, a component of turmeric (Curcuma longa), has antidepressant activity? Natural medicine has much to offer individuals who suffer from mild to moderate depression, and increasingly, we have things to offer for those with major depression. One of the problems with conventional treatments, is that nearly 50% of patients with major depressive disorders discontinue their medication due to side effects. Finding treatments that do not cause side effects, then becomes much needed area of optimal management. Curcumin, a component of turmeric rhizome has been studied in several clinical trials, but the current paper is a meta-analysis the evaluated the safety and effectiveness of curcumin in treating major depressive disorder.

The meta-analysis of the literature that was searched included those that met the following criteria: (1) human study, (2) quantitative analysis, (3) intervention and control group, (4) curcumin was an independent intervention, (5) study addressed only major depressive disorder, (6) depression was measured with standardized scales, and (7) the study was in English. Studies were also rated according to quality and the data from all the studies were converted into Hamilton Depression Rating Scale scores.

A total of 1757 studies were identified, and six met all the inclusion criteria which totaled 342 patients (n=177 curcumin and n=165 control). There were four randomized controlled trials, one crossover study, and one open-label study. All patients received an antidepressant prescription medication in addition to either curcumin (1 g/day, n = 5 studies or 500 mg/day, n = 1 study) or placebo. Five of the studies rated strong in quality and one was moderate.

In this meta-analysis there was a significant reduction in major depressive symptoms with curcumin treatment compared with control. In addition, several subgroup analyses demonstrated that curcumin had a significant benefit in middle-aged patients but not older-aged patients, although age ranges were not defined; curcumin had a significant benefit in patients treated for > 6 weeks but not in patients treated for < 6 weeks; 500 mg / day of curcumin did not have an effect but 1,000 m g/day did have a significant benefit; and curcumin had a significantly greater benefit in those patients who only had major depressive disorder vs. those with major depressive disorder and other chronic health problems.

Commentary:

This appears to be the first meta-analysis of the effect of curcumin on major depressive disorder. Summary conclusions are that curcumin is effective in reducing symptoms of depression in patients with major depressive disorder and are already taking prescription antidepressants, and that curcumin is more effective in middle-aged patients. Effective doses were 1 g/day for > 6 weeks. A few cautionary notes with this meta-analysis are that there were only 6 studies; only two doses of curcumin were evaluated; the piperine used to enhance curcumin and/or the doses of curcumin may not have been optimal and that the study was quite short term for such a chronic condition. On the other hand, the methodology the authors used was rigorous and I am encouraged by the research on curcumin and depression.

Fenugreek seed has a long tradition of being used as an a466762923gent to increase the production of breast milk (“galactagogue”). There is general agreement among health care advisory organizations, including the World Health Organization, breast feeding is recommended for at least 6 months, due to its short and long term health benefits to the recipient. Not all women have sufficient milk production to succeed in a 6-month duration, and simple, safe methods are welcome options. The goal of this randomized, controlled, double-blind, clinical trial was to evaluate the effect of a fenugreek seed herbal tea on the signs of breast milk sufficiency in female infants from birth to the age of 4 months.

The study was conducted in Tehran, Iran and included 78 healthy female infants and their mothers. The infants weighed between 5.5 and 8.8 lbs., had normal sucking ability, were not consuming infant formula or other sources of nourishment. No other herbal or pharmaceutical agents were being used by the women to promote lactation.

The lactating women were randomly assigned to receive an herbal tea containing 7.5 g fenugreek seed powder in addition to 3 g black tea powder (n=39) or to the control group that was an herbal tea containing 3 g black tea powder (n=39). Teas were consumed 3 times per day, 2 hours after each meal for 4 weeks.

Growth measurements included infant weight, height, and head circumference and were done at baseline and each weekly visit. Mothers completed questionnaires about demographic factors and breastfeeding conditions and completed a 2-day account of the number of daily wet diapers, frequency of infant defecation, and the number of times they breast fed each day.

Upon entry into the study, women in both groups had similar body mass index, age, and similar infant weight, height, or head circumference.

After 4 weeks of teas: weight, head circumference, number of wet diapers, frequency of defecation, and number of breastfeeding times increased significantly in the fenugreek group compared with baseline. The growth in infant height was not different between the two groups. Growth in height difference between the 2 groups was not significant.

Commentary: While this was a small study, and the use of fenugreek teas was used in conjunction with black tea, it appears that fenugreek seed did improve signs of breast milk sufficiency. It would have been useful to know how much fenugreek seed was in the tea, how the tea was prepared as we do not know if it was an infusion or a decoction or even just mixing the powder into hot water and instantly drinking. It would also be useful to know how much liquid was consumed in each unknown amount of tea. I would also want to know if this approach could help a woman reach the goal of 6 months of lactation. All of that said, this study in my view, supports the tradition of fenugreek in promoting milk supply in lactating women, and supports the usefulness of it in women who want to assure the delivery of adequate milk to their infants.

185081880Premenstrual syndrome (PMS) includes one or more of many symptoms in the areas of mood, the physical body and cognition. The most frequent symptoms are irritability, depression, fatigue, water retention, weight gain, breast tenderness, headaches, abdominal cramps and mood swings. About 80% of women may experience PMS and about 50% of women seek medical care for their symptoms.

The primary etiology of PMS has been thought to be the interplay of serotonin and hormones which is why conventional treatment of PMS most often includes SSRIs to increase serotonin levels and/or birth control pills to suppress ovarian hormone secretion.

High sensitivity C-reactive protein (hs-CRP) is an acute phase inflammatory marker that has been associated with risk for cardiovascular disease and menopausal hot flash symptoms. It has also been associated with some of the risk factors for PMS including depression, smoking, increased body mass index (BMI) and aging. Some studies have investigated the role of inflammation and PMS but only suggestive not significant connections have been observed. Select anti-inflammatory medications can also provide relief for some PMS symptoms.

The current study used data on PMS symptoms from a much larger study called the Study of Women’s Health Across the Nation (SWAN), a racially and ethnically diverse study of midlife women from five racial/ethnic groups and at seven clinical sites nationwide. The goal was to determine if hs-CRP was associated with PMS. The proportion of women who reported each PMS symptom, except breast pain or headaches, was significantly increased (26%-41%) for women who had hs-CRP values > 3 mg/L. A hs-CRP level > 3 mg/L in women with PMS was associated with mood symptoms, abdominal cramps, back pain, appetite cravings, weight gain, and bloating, but not with headaches, breast pain for women with three or more PMS symptoms.

Most symptoms, except for headaches and breast pain were reported by significantly more obese women, women who smoked or were exposed to passive smoke and by women with an elevation of depressive symptom scores.

Commentary: There has been very little literature that has focused on any relationship between inflammation and PMS. The current study that does observe a significant relationship with at least some PMS symptoms and in women who have less than 3 PMS symptoms suggests that inflammation may be involved in PMS. That said, I would not abandon the serotonin-hormone connection and would continue to recognize that PMS is likely a complex disorder with potentially different mechanisms for the etiologies of at least some of the symptoms. In addition to biology, there are numerous social, demographic and behavioral factors that are likely associated with PMS. The lifestyle and natural agents that have published research support that I rely on the most in clinical practice are aerobic exercise 4 or more times per week, St John’s wort, calcium, vitamin B6, chaste tree, magnesium, vitamin E and borage seed or evening primrose oil. For more difficult mood disorder PMS patients, usually called premenstrual dysphoric disorder (PMDD), I add one or more of the following: tryptophan, theanine, lavender, GABA, SAMe and more.

Polycystic ovarian syndrome (PCOS) is a common endocrine problem that is486352462 diagnosed in reproductive aged women. It’s complex and involves multiple body systems but is associated with hyperinsulinemia, impaired glucose metabolism, hyperandrogenism and dyslipidemia. It is estimated that 5-6 million women in the United States have PCOS. The manifestations of PCOS can include irregular/infrequent menses or no menses at all, infertility, polycystic ovaries, abnormal hair growth (hirsutism), hair thinning, acne, weight gain and in time, an increased risk for type 2 diabetes, cardiovascular disease and endometrial cancer.

PCOS is a strong area for natural medicine that includes good science on nutrition, exercise, N-acetyl cysteine, myo-inositol, d-chiro-inositol, cinnamon, spearmint, licorice, fish oils and more.

The current study compared women who received a soy isoflavone supplement for 12 weeks with placebo. The study enrolled 70 women between the ages of 18 to 40, and who met the diagnostic criteria, called the Rotterdam criteria, for a diagnosis of PCOS. Women were given either a 50 mg soy isoflavone capsule per day or a placebo daily, for 12 weeks. All women also took metformin at 500mg/day which was increased to 1,500 mg/day. One of the uses of metformin is to improve insulin sensitivity which in women with PCOS, hopefully leads to lowered androgens and regular ovulation with regular menses. No other dietary supplements were allowed.

The women who took the soy isoflavone supplement had significantly improved insulin resistance (measured by a decrease in serum insulin levels and two other important tests that measure insulin resistance and insulin sensitivity called the HOMA-IR and the QUICK1), as well as improvement in androgen levels and triglycerides.

Commentary: Soy foods in the diet of women with PCOS have been a staple of my nutritional advice for women with PCOS, due to other evidence that soy phytoestrogens can improve lipids and lower some of the free testosterone. I would not be inclined to just rely on a soy isoflavone supplement or soy foods to fully address PCOS, but in terms of medicinal foods, soy foods and/or a soy isoflavone supplement is an important dietary influence for women with PCOS. Do not be misled by the term “phytoestrogen”, some of the natural compounds in soy. Soy does not contain estrogen nor does it increase estrogen levels, nor does it cause hormonal cancers.

494150385Migraines are chronic and debilitating and affect 12-20% of the world’s population, and are more common in women. Women account for about three quarters of the 28 million Americans who experience migraine headaches. Attacks can begin at any age, but they typically start during childhood or adolescence when they are pretty equal in boys and girls. By early adolescence though, the prevalence becomes more dominant in women. This prevalence of migraines peaks in women in their early forties, and then declines steadily as we age, but may not resolve completely. Migraines tend to reduce in frequency in postmenopausal women, with estrogen levels decreasing significantly and also stabilizing without monthly fluctuations.

Only about half of patients achieve a 50% reduction in the frequency of their attacks, despite the availability of prophylaxis options. Sadly, only 3-5% of chronic migraine sufferers receive adequate prophylaxis therapy.

A randomized, multi-center, parallel-group design was conducted in which melatonin was compared with amitriptyline and placebo for 12 weeks. Patients were randomized into one of three groups: placebo, melatonin 3 mg or amitriptyline 25 mg before bed, daily. After a 4-week baseline phase, 196 patients were randomized with 65 in the placebo group, 66 received amitriptyline and 65 received melatonin. Those numbers in each group decreased slightly as 18 were lost to follow-up.

Patients were men and women ages 18-65 and had migraines with or without aura for at least 1 year and first onset prior to age 50 years. Patients were included in the study if they had at least three migraine headache attacks or four migraine headache days (a headache of at least 30 minutes in duration) per month but < 15 headache attacks over month during each of the previous 3 months prior to the screening visit. Patients were excluded if they had a past or present psychiatric disorder, used ergotamine, triptan medications, opioid or combinations of those for > 10 days per month or just an analgesic for > 15 days/month for > 3 months. They were also excluded if they were unable to discontinue their prophylactic medications, or had previously taken melatonin, amitriptyline or agomelatine or had uncontrolled hypertension at the screening visit or at randomization.

Mean headache frequency reduction was 2.7 migraine headache days in the melatonin group, 2.2 for amitriptyline and 1.1 for placebo which means that melatonin was as effective as amitriptyline in the primary endpoint of frequency of migraine headaches per month. Melatonin was superior to amitriptyline in the percentage of patients with a greater than 50% reduction in migraine frequency and melatonin was better tolerated than amitriptyline. Melatonin and amitriptyline were both more effective to placebo in reducing the number of analgesics used, and the duration and intensity of migraine headache attacks.

Commentary:

The process of migraines is multifactorial- neurological, vascular, muscular. What we now think is that it can begin when the sensitive nervous system of a migraine sufferer is faced with an environment that can reduce their migraine threshold. These risk and trigger factors include hormonal changes, alcohol consumption, skipping meals, sleep deprivation, medications, and other stressors. Under these circumstances, the neurochemical balance of the nervous system changes, and prodromal symptoms can occur. If this state progresses, the migraine threshold is crossed, and the “migraine generator” area of the brainstem is now activated. A wave like effect occurs across the cerebral cortex- neurons are affected and the trigeminal nerve branches and the vascular structures it supplies are activated. As the branches of the trigeminal nerve are activated, neuropeptides are released from the nerve. These then produce an inflammation of small arteries in the meninges which stimulate platelet aggregation and serotonin release, potentiating the migraine process. Nerve impulses are transmitted back to the brainstem and as the process continues, brainstem reflexes are activated that produce the migraine related symptoms, ex/ nausea, vomiting and photophobia. Pain fiber activation can also result in nasal congestion and pain in the sinus cavities.

While this study did demonstrate efficacy of clinical import, we can do even better. I would definitely incorporate melatonin 3 mg/day into my prophylaxis approach to migraine… in which I am intending to reduce not only frequency, but duration and severity as well.

157431721I’m regularly looking for more satisfactory results for treatment of acne vulgaris— those nasty pimples most commonly on the facial area. There are multiple factors that cause acne, but a few of those factors includes and excessive production of sebum, an immune response to the bacteria called Propionibacterium acnes, inflammation and abnormal cell turnover of skin cells.

Tea tree leaf oil is one of those plant compounds that has demonstrated both antimicrobial and anti-inflammatory properties. Previous studies have shown effectiveness of tea tree oil in treating acne but they used higher concentrations of the oil (up to 5%) that are currently not available in commercially available products. The purpose of this study was to see if a commonly available tee tree oil gel and facial wash might work for mild to moderate acne.

Both men and women with mild to moderate acne were recruited in Australia. They were ages from 16-39 y.o. Study participants received 200 mg/g of a Tea Tree medicated gel and 7 mg/g Tea Tree Face Wash for Acne. Study subjects used the products twice daily on their face. They applied 1 pump of the face wash, patted it dry, and then applied a small amount of the gel in a thin layer on the acne areas and leave it on for at least 6 hours and then wash it off right before the next application.

The total number of acne lesions were recorded and scored at baseline, 4, 8 and 12 weeks. The amount of skin oiliness was also recorded by the researcher at those same time intervals. Patients also kept a diary and at the end of each week, they recorded their acne on a 5 point scale ranging from worse to significantly better. Tolerance to the tea tree applications were also scored by the investigator. A laboratory testing of the susceptibility of the acne bacteria to the oil and gel and face wash was also done and the minimum inhibitory concentration (MIC) of each product was determined. The MIC of the unformulated oil ranged from 0.25% to 1% which means that 90% of the isolates were inhibited by 1%. The MIC of the gel ranged from 0.062-0.5% and the MIC of the face wash was < 0.25%.

Results: Mean total lesion count significantly decreased at each visit with a 25% decrease at 4 weeks, 37% decrease at 8 weeks and 54% decrease at 12 weeks. The investigator assessment score was significantly better at weeks 8 and 12 compared to baseline. Facial oiliness was significantly improved at week 12 compared to baseline. Clinical efficacy of 40% or greater in lesion count at 12 weeks occurred for 79% (11/14) of the individuals. The weekly opinion of almost half of the men and women with acne was that their acne was about the same or slightly improved by 43%.

No serious adverse events occurred but there was one person who reported minor itching, one with moderate scaling and 1 had moderate peeling and 1 had moderate dryness. The average tolerability scores for erythema and peeling were significantly decreased by the end of the 12 weeks.

Summary and commentary: The use of the gel and face wash containing tea tree oil for 12 weeks did seem to significantly reduce the number of acne lesions and was pretty well tolerated in men and women with mild to moderate acne. Both the gel and face wash showed significant antibacterial activity in the laboratory part of the study which would imply that this mechanism is at least in part, how tea tree works for mild to moderate acne.

Acne is a very common skin condition and I welcome some confirming evidence for tea tree gel and face wash that may help more folks with this pesky problem. It won’t be as simple as that to cure this type of acne. Other influences and strategies that might need to be addressed would include hormonal, diet and stressors.
