The Efficacy of Herbal Supplement for Relieving Menopausal Symptoms.

OBJECTIVES

This study aimed to further explore the efficacy and safety of (DBT), a simple herbal formula, for improving the quality of life of women suffering from menopausal symptoms.

METHODS

A third clinical trial to determine the clinical efficacy of high-dose DBT for a period of 12 weeks was carried out. The standard Menopause-Specific Quality of Life (MENQOL) assessment chart was used for the evaluation. Safety was defined as an absence of direct estrogenic effects, serum inflammatory cytokines. Notably, interleukin IL-6, IL-8 and tumor necrosis factor TNF-α, known to be directly related to estrogenic reactions in menopause studies, were monitored.

RESULTS

The third clinical trial indicated an overall improvement in the four domains of MENQOL, offering further proof of the efficacy of DBT demonstrated in the two previous trials. The serial checks of the three cytokines related to estrogen activities did not show either upward or downward trends. The haphazard behavior reactions of the three cytokines offered indirect indications that DBT improved the MENQOL independently from estrogen activities.

CONCLUSIONS

The three clinical trials using DBT to relieve menopausal syndrome have offered solid evidence for its efficacy. The uncertainty regarding whether the "phytoestrogen" contained in DBT had bioactivities similar to estrogen was alleviated through the confirmation that no strict estrogenic bioactivities were observed. The issue of safety was further clarified via laboratory platform studies on DBT, which not only showed the lack of similarity with estrogen actions but also confirmed the value of combining the two herbs in the classic formula.
