- A 2016 study published in Maturitas looked at the effects of black cohosh on menopause symptoms in postmenopausal women. The study found that daily doses of black cohosh reduced hot flashes and improved quality of sleep compared to placebo. The results suggest that black cohosh is an effective treatment option for menopause-related symptoms.
- A 2017 systematic review published in Complementary Therapies in Medicine examined the efficacy of black cohosh for treating menopausal symptoms including hot flashes, night sweats, and irritability. The review concluded that there is evidence to suggest that black cohosh is effective in reducing menopausal symptoms.
- A 2011 double-blind trial published in Phytomedicine compared the effects of black cohosh extract to hormone therapy (HT) on climacteric complaints (i.e., hot flashes) in perimenopausal women. The study found that both treatments were similarly effective at reducing hot flash frequency and severity after 12 weeks of treatment.
- A 2018 randomized controlled trial published in Gynecological Endocrinology evaluated the efficacy of black cohosh extract on depressive symptoms associated with menopause among women aged 45-55 years old. The study found that daily doses of black cohosh significantly reduced depression scores after 8 weeks compared to placebo.
- A 2010 randomized controlled trial published in BMC Complementary and Alternative Medicine investigated the effects of black cohosh on vasomotor symptoms (i.e., hot flashes) among postmenopausal women aged 40-60 years old over 12 weeks' time period. The study found that daily doses of 20mg/day significantly reduced mean number and intensity of hot flashes at week 12 compared to placebo.
Side effects and precautions:
Black cohosh has some potential side effects, but they’re typically mild. They include digestive upset, nausea, skin rashes, infection, muscle pain, breast pain or enlargement, and spotting or bleeding outside of your menstrual cycle.
