Weight gain in menopause: systematic review of adverse events in women treated with black cohosh

Traditional uses, phytochemistry, pharmacology, quality control and clinical studies of Cimicifugae Rhizoma: a comprehensive review

Cimicifugae Rhizoma, generally known as "Sheng Ma" in China, has great medicinal and dietary values. Cimicifugae Rhizoma is the dried rhizome of Cimicifuga foetida L., Cimicifuga dahurica (Turcz.) Maxim. and Cimicifuga heracleifolia Kom., which has been used to treat wind-heat headache, tooth pain, aphtha, sore throat, prolapse of anus and uterine prolapse in traditional Chinese medicine. This review systematically presents the traditional uses, phytochemistry, pharmacology, clinical studies, quality control and toxicity of Cimicifugae Rhizoma in order to propose scientific evidence for its rational utilization and product development. Herein, 348 compounds isolated or identified from the herb are summarized in this review, mainly including triterpenoid saponins, phenylpropanoids, chromones, alkaloids, terpenoids and flavonoids. The crude extracts and its constituents had various pharmacological properties such as anti-inflammatory, antitumor, antiviral, antioxidant, neuroprotective, anti-osteoporosis and relieving menopausal symptoms. The recent research progress of Cimicifugae Rhizoma in ethnopharmacology, phytochemistry and pharmacological effects demonstrates the effectiveness of its utilization and supplies valuable guidance for further research. This review will provide a basis for the future development and utilization of Cimicifugae Rhizoma.

Exploring the Efficacy and Safety of Black Cohosh (Cimicifuga racemosa) in Menopausal Symptom Management

Black cohosh (Cimicifuga racemosa) is a perennial plant used to treat menopause. This plant is known to have a serotonergic rather than estrogenic impact. It has been recommended to treat vasomotor symptoms associated with breast cancer patients. It also relieves symptoms such as night sweats and hot flashes, commonly called vasorelaxation. The variability in the study's results, doses, and assessment methods requires more rigorous research to establish its efficacy and safety. Standardized trials are needed to provide more precise information on the benefits and limitations of menopause treatment, informing women seeking alternatives to hormone therapy. Black cohosh has shown the potential to reduce the frequency and intensity of vasomotor symptoms in breast cancer patients undergoing tamoxifen treatment. In addition to its effectiveness in alleviating night sweats and hot flashes, the vasorelaxation properties contribute to its overall positive impact on menopausal symptoms. Due to discrepancies, varying dosages, and assessment techniques, further comprehensive studies are essential to determine the optimal dosage, long-term safety, and overall efficacy. Only through standardized trials can women make informed decisions about black cohosh as a viable alternative to hormone therapy during menopause.

Black cohosh efficacy and safety for menopausal symptoms. The Spanish Menopause Society statement

OBJECTIVE

The increasing interest in Western countries regarding phytotherapy use to treat menopause-related symptoms has led the Spanish Menopause Society (AEEM) to update its position statement performed in 2009 on the role of black cohosh (Cimicifuga racemosa) for the treatment of menopausal symptoms.

MATERIAL AND METHODS

A panel of experts from both clinical and research backgrounds were assembled to investigate the best available evidence. Selected studies were obtained by an electronic search, including the Internet search engines MEDLINE-Pubmed (1997-December 2021) and the Cochrane Controlled Trials Register.

RESULTS

Most of the well-designed studies published in recent years have been conducted with the isopropanolic extract of black cohosh/C. racemosa. The most common dose is 40 mg/day capable of achieving a significant reduction in hot flushes (particularly in women with intense hot flushes) and an improvement in mood. Used at the recommended doses, C. racemose produces no significant adverse reactions.

CONCLUSION

Black cohosh is an effective and safe treatment option for the relieving of vasomotor symptoms. Finally, further clinical trials with sufficient patient enrollment and longer study follow-up are needed.
