Chinese Herbal Formula May Significantly Reduce Hot Flashes in Menopausal Women

Menopause can create unnecessary hardships during the later stages of women's lives, and hot flashes in particular can be particularly frustrating as they can come on at any particular time. However, according to a recent study, women taking a Chinese herbal formula experienced less than half of  the number of menopausal hot flashes they had before the treatment.

Researchers from Hong Kong said that women who used the herbal formula experienced less than half the number of menopausal hot flashes prior to receiving the treatment.

Among women taking an herbal mix called Er-xian decoction (EXD), the frequency of daily hot flashes dropped by 62 percent, compared to a 52-percent drop seen among women taking a placebo, according to WKZO.

"It's a modest effect, but not a zero effect," said Katherine Newton, a researcher who has studied herbal menopause therapies at the Group Health Research Institute in Seattle.

Newton, who was not involved in the research, said she'd want to see more, long-term studies demonstrating that these herbs are safe before she would recommend them to women, but that the current study makes EXD look promising as an alternative menopause treatment.

While hormone replacement therapy is considered the most effective therapy for menopause-related symptoms, many potential health risks exist for women looking for alternatives, said Yao Tong, a professor at the University of Hong Kong and one of the authors of the new study.

Er-xian decoction (EXD) contains compounds extracted from the roots, stems or leaves of six Chinese herbs, processed into granules then packaged in sachets to be made into a tea.

To get a more reliable assessment of how well EXD works, they asked 101 women in their 40s and 50s, who were at or near menopause and experiencing symptoms, to drink an herbal formula twice a day for 12 weeks.

Half of the women drank a 15 gram dose of EXD, while the other half drank a fake remedy that consisted of tea, caramel and an herbal compound called gardenin.

For two weeks prior to the treatment, the women logged their hot flashes.

Those in the EXD group reported an average of 5.8 hot flashes each day, and those in the other group experienced five daily.

After the treatment, the number of hot flashes dropped to 2.2 in the EXD group and 2.5 in the other group.

Three months after the treatment ended, hot flashes stayed put at 2.2 a day for women who had drank EXD, while they went up slightly to 2.9 a day for women who had drank the placebo.
