OBJECTIVE This study sought to confirm the efficacy and safety of the currently recognized dose of Cimicifugae racemosae rhizoma (40 mg/day) and to evaluate a higher dose and its associated physiological effects. METHODS We conducted a controlled, randomized, double-blinded parallel group study of perimenopausal and postmenopausal women treated with two different doses (39 mg and 127.3 mg) of a unique C. racemosa preparation over a 24-week period. Efficacy and tolerability were determined by…

Actaea racemosa L. Is More Effective in Combination with Rhodiola rosea L. for Relief of Menopausal Symptoms: A Randomized, Double-Blind, Placebo-Controlled Study

BC is more effective in combination with RR in relief of menopausal symptoms, particularly psychological symptoms and RR-BC significantly improved the QOL index in patients, compared to BC, BC500, and placebo, mainly due to the beneficial effects on the emotional and health domains.

Dose-Dependent Effects of the Cimicifuga racemosa Extract Ze 450 in the Treatment of Climacteric Complaints: A Randomized, Placebo-Controlled Study

The CR extract Ze 450 is an effective and well-tolerated nonhormonal alternative to hormone treatment for symptom relief in menopausal women and reported adverse events and clinical laboratory testing did not raise safety concerns.

[Efficacy and safety of Black cohosh (Actaea/Cimicifuga racemosa) in the treatment of vasomotor symptoms--review of clinical trials].

Professional literature about Black Cohosh (Actaea/Cimicifuga racemosa), either used alone or in combination with other medicinal herbs administered in management of vasomotor symptoms, is reviewed, finding that Open-label, noncomparative studies, as well as treatment-controlled, randomized, open trials, have proven that Black CohOSH significantly reduced frequency or severity of hot flashes.

Effects of extracts from Cimicifuga racemosa on gonadotropin release in menopausal women and ovariectomized rats.

It is concluded that the LH suppressive effect of C.r. extracts observed in menopausal women and ovx rats is caused by at least three different synergistically acting compounds.

While both genistein and estradiol altered ovarian and testicular steroid release and decreased circulating testosterone levels in males, neither black cohosh total extract, 25-O-methyl-cimigenoside, actein, nor 26-deoxy-actein caused any differences in estrogenic activity compared to control fish.

Cimicifuga racemosa Extract Inhibits Proliferation of Estrogen Receptor-positive and Negative Human Breast Carcinoma Cell Lines by Induction of Apoptosis

Results indicate that C. racemosa extract exerts no proliferative activity, but kills the estrogen receptor positive MCF-7 as well as estrogen receptor negative MDA-MB231 cells by activation of caspases and induction of apoptosis.

Comparative clinical evaluation of estrogenic preparations by the menopausal and amenorrheal indices.

It is desirable that the relative activity of estrogens be based upon human ‘assay’ rather than biologic or chemical standardization procedures, because greater variability of response and less predictability of results occur than in animal assay procedures.

Black cohosh: an alternative therapy for menopause?

Results from the most recently published trial indicate that black cohosh is not effective for the treatment of menopausal symptoms in breast cancer survivors being treated with tamoxifen, and two new randomized, double-blind, placebo-controlled clinical trials are currently underway in the United States.
