Abstract

OBJECTIVE: To determine the optimal dose, safety, and efficacy of an estrogen receptor β selective Chinese herbal extract, menopausal formula 101 (MF101), for treating hot flushes. METHODS: A randomized, blinded trial in 217 postmenopausal women with hot flushes randomized to 5 or 10 g/day of MF101 or placebo for 12 weeks. RESULTS: The effects of 5 g/day of MF101 did not differ from those of placebo. After 12 weeks, the mean percent decrease in frequency of hot flushes in the 10 g/day group was 12.9% greater than that in the placebo group (P = 0.15), the median percent decrease was 11.7% greater than that in the placebo group (P = 0.05), and the proportion of women with at least a 50% reduction in hot flushes was 16.2% greater than that in the placebo group (P = 0.03). CONCLUSIONS: Treatment with 10 g/day of MF101 reduces the frequency of hot flushes. Trials with higher doses are planned.
