Abstract

OBJECTIVE:

The aim of the study was to investigate the effectiveness and safety of a new, improved herbal formula of a traditional Chinese medicine, improved Gengnianchun (I-GNC), on hot flushes, depression, anxiety, and sleep in peri- and postmenopausal women in China.

METHODS:

A randomized, single-blind, placebo-controlled trial of peri- and postmenopausal women with Kupperman Index (KMI) scores of 15 or higher was conducted for 12 weeks. Hot flush frequencies, KMI scores, Hamilton depression scale scores, Hamilton anxiety scale scores, and Pittsburgh Sleep Quality Index scores were evaluated. Each outcome was evaluated every 4 weeks.

RESULTS:

Ninety-eight participants completed the study. The I-GNC formula significantly reduced the mean (SD) frequency of hot flushes from 7 (4.554) to 1.2 (1.675) in the I-GNC group and from 6.74 (3.43) to 3.66 (2.635) in the placebo group (P < 0.01). The KMI (P < 0.01), Hamilton depression scale (P < 0.01), and Hamilton anxiety scale (P < 0.01) scores decreased in both groups after treatment, and significant differences were observed between the two groups (P < 0.01); however, no significant difference in the Pittsburgh Sleep Quality Index score was observed. I-GNC had no effect on serum follicle-stimulating hormone or E2 levels. There were no obvious adverse effects.

CONCLUSIONS:

The traditional Chinese medicine herbal formula I-GNC can alleviate the symptoms of menopausal syndrome and improve quality of life among peri- and postmenopausal women. I-GNC is safe and has no notable adverse effects.
