St. John's Wort and Menopause

St. John’s wort products and extracts have been used for a wide range of medical conditions, the most common being depressive disorders. The most robust research is in the area of mild to moderate depression, with some additional research in anxiety, severe depression, seasonal affective disorder, premenstrual syndrome, and perimenopause/menopause. St. John’s wort is the most thoroughly researched natural antidepressant, but the majority of these studies have not been conducted on menopausal women.

A study of St John’s wort liquid extract showed a statistically decline in hot flashes severity, duration and frequency in the SJW group compared to placebo at week 8.[1]

Another double blind randomized clinical trial demonstrated that after 3 months of treatment, women in the St. John’s wort group reported significantly better quality of life scores, and significantly fewer sleep problems compared to placebo. [2]

About ten years ago, a non placebo controlled, drug monitoring study was conducted in women with menopause symptoms using 900 mg of St. Johns wort for 12 weeks. About three quarters of the women experienced improvement in both the self-rating scale and the physician rating, and significantly improved in psychological and psychosomatic symptoms as well as a feeling of sexual well-being.[3]

The first of three studies using St. John’s wort and black cohosh was published in 1999. This double-blind, randomized, placebo-controlled trial used St. John’s wort and black cohosh made by the makers of Remifemin.[4] The Kupperman index for the combination product decreased from 31.4 to 18.7 compared with a decrease in the placebo group from 30.3 to 22.3. Psychological symptoms also improved significantly in the black cohosh/St. John’s wort combination group.

A double-blind randomized placebo-controlled study was done using a combination trial of black cohosh and St. John’s wort. The mean Menopause Rating Scale score decreased 50% in the treatment group and 19.6% in the placebo group.[5] The Hamilton Depression Rating Scale score decreased 41.8% in the treatment group and 12.7% in the placebo group. In both testing measures the St. John’s wort + black cohosh group was significantly superior to the placebo group.

Another black cohosh/St. John’s wort trial was carried out in peri or postmenopausal Korean women, and was published in 2007.[6] Mean Kupperman index scores at 4 and 12 weeks were significantly lower in the treatment group (P < 0.002). At the end of the study, the average decrease in the Kupperman Index was 20 points in the treatment group and only 8.2 points in the placebo group (P < 0.001). Vaginal dryness and low libido were two symptoms that did not improve, but the average hot flash scores were significantly lower in the black cohosh/St. Johns wort group.

Finally, a study was done in which a combination of black cohosh with or without St. John’s wort was used in 6141 women at 1287 outpatient gynecologists in Germany in a prospective, controlled open-label observational study.[7] The greatest changes occurred with the combination therapy for nervousness/irritability and mood swings, but in the area of depression, there was a reduction in both treatment groups.

St. John’s wort is emerging as an important clinical tool in treating perimenopausal/menopausal women—for hot flashes and/or depression and/or mood swings, as a single agent, or in combination with other therapies.

St. John's Wort and Menopause by Dr Tori Hudson

Several studies of St. John’s wort alone and St. John’s wort with black cohosh have been able to demonstrate that these products are good options for perimenopausal and menopausal women with hot flashes, mood issues, sleep problems and quality of life.

In the newest of the St. John’s wort studies in perimenopausal/menopausal women, a total of 100 Iranian women with an average age of 50 participated in a randomized, double-blind, placebo-controlled clinical trial comparing St. John’s wort with placebo in the treatment of hot flashes.[1] 50 women received 20 drops three times daily of St. John’s wort extract (Hypericin) that contained hypericin 0.2 mg/mL and 50 women received a placebo of distilled water. The study duration was two months. Clinical exams and interviews were performed at baseline, 4 weeks and 8 weeks. Treatment effectiveness was measured evaluating frequency, duration and severity of hot flashes as the main objective of the study.

In women taking St. John’s wort, the frequency began to decline during the 1st and 2nd months, but showed more improvement during the 2nd month. There was no statistical change in hot flash frequency during the first month of placebo but did improve during the second month. Women who used St. John’s wort showed more improvement in hot flash frequency than placebo. The decline in duration of hot flashes was statistically significant at week 8 and the decline was much more evident in the St. John’s wort group. The severity of hot flashes was relieved in the St. John’s wort group during the 2 months of treatment and was more significant in the second month. Women in the placebo group did not show any significant decrease in severity of hot flashes during the 1st month, but they did have some improvement during the 2nd month, but not as great as those women in the St. John’s wort group.

Comments
St. John’s wort has emerged as an important clinical tool in treating perimenopausal/menopausal women—for hot flashes and/or depression and/or mood swings, and/or sleep problems either as an encapsulated standardized extract from 300 mg twice per day to three times per day, or a tincture/liquid extract ½ tsp 2-3 times per day, or in combination with other menopause therapies such as black cohosh, maca extract, kava or others.

St. John's Wort for treatment of Premenstrual Syndrome (PMS) by Dr Tori Hudson

The results of a randomized, double-blind, placebo-controlled crossover trial using St. John’s Wort for PMS sufferers were recently published. 36 women with regular menstrual cycles who were diagnosed with mild PMS were randomly assigned to receive St. John’s Wort tablets (900 mg/day and standardized to 0.18% hypericin and 3.38% hyperforin) or placebo for two menstrual cycles. After a one month no treatment cycle, women were crossed over to the opposite group, for two additional cycles.

Symptoms were rated using the Daily Symptom Report, The State Anxiety Inventory, the Beck Depression Inventory and the Aggression Questionnaire and Barratt Impulsiveness Scale. Numerous hormones and physiological markers were also measured in the follicular and luteal phases: follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, prolactin, testosterone, cytokine interleukins= IL-1B, IL-6, IL-8, interferon and tumor necrosis factor alpha.

St. John’s wort was statistically more beneficial than placebo in food cravings, swelling, poor coordination, insomnia, confusion, headaches, crying and fatigue. There were no significant effects of St. John’s wort compared with placebo in any of the biochemical blood measurements. St. John’s wort was not statistically more beneficial in anxiety, irritability, depression, nervous tension, mood swings, feeling out of control and pain-related symptoms during two cycles of treatment. However, these pain-related symptoms appeared to improve more than placebo towards the end of each treatment period.

Commentary: The results of this PMS study demonstrate once again, the benefit of St. John’s Wort for the treatment of PMS. In this study, it was determined their PMS was mild. The benefit received by women taking St. John’s Wort was achieved during the first menstrual cycle in which it was taken. While St. John’s Wort did not prove to be statistically better than placebo for mood and pain-related PMS symptoms, the pain symptoms did appear to improve more than placebo towards the end of each treatment period, implying that there may be more pain benefits with St. John’s wort after a longer duration of treatment. Several other studies have shown benefit with St. John’s wort.

St. John's Wort and Perimenopause by Dr Tori Hudson

This double-blind, randomized clinical trial, studied the effect of Hypericum perforatum extract (St. John’s wort extract) compared with placebo, on symptoms and quality of life of 47 symptomatic perimenopausal women aged 40 to 65 with three or more hot flashes per day. Women were randomly assigned to receive a St. John’s wort extract (900 mg three times per day) or placebo. The women used a daily diary to record hot flash severity and frequency during the week before the study group selection process and again for a week before the end of the three month follow-up. The Menopause-Specific Quality of Life questionnaire was also used.

RESULTS: After 12 weeks of treatment, a non-significant difference in favor of the St. John’s wort group was observed in the daily hot flash frequency and the hot flash score. However, after those three months of treatment, women in the St. John’s wort group reported significantly better quality of life scores, and significantly fewer sleep problems compared to placebo.

Commentary: St. Johns wort research is expanding into the realm of use for perimenopause and menopause symptoms. Other recent studies have reported improvement in psychological, well-being and quality of life in symptomatic perimenopausal and menopausal women. In the current study, while not especially helpful for hot flashes, there was an improvement in quality of life scores and sleep problems. I commonly use St. Johns wort with black cohosh for women with hot flashes and mood issues during perimenopause and menopause. The research on each and even two studies using the combination of the two reveal that these two plants in combination are a premium option for perimenopausal and menopausal women with some of the most common of symptoms.
