When Helen Marsh, 52, started experiencing hot flashes that woke her three times every night, she assumed she had two choices: grit her teeth or take hormone therapy. Like many women navigating menopause, she didn't know there might be another path.
A sweeping new review published earlier this year is illuminating what actually works for the constellation of symptoms that affect women typically between ages 45 and 55. Researchers analyzed 158 clinical trials and systematic reviews examining 86 different complementary approaches — from acupuncture needles to herbal formulas passed down through generations.
"Women deserve to know what the evidence actually shows," said one of the researchers involved in the review.
The findings are nuanced but genuinely hopeful. Black cohosh, a flowering plant used for centuries, improved both overall menopause scores and hot flash frequency when taken for anywhere from four weeks to a full year. Perhaps most remarkably, not a single study reported serious side effects.
Soy-derived isoflavones — plant compounds that mimic estrogen in the body — also reduced hot flashes and improved overall symptom scores. The same was true for Chinese herbal medicines: 70 trials showed that formulas taken for anywhere from one week to three months led to meaningful improvements in both menopause symptoms and sleep quality. The most studied formula was Suan Zao Ren Tang, a traditional blend that translates roughly to "wild jujube seed decoction."
Of course, the researchers urge caution with some supplements. Long-term vitamin D and calcium use — beyond seven years — may increase cardiovascular risk in women without osteoporosis or vitamin D deficiency, so those should be taken under medical supervision.
For the millions of women who either cannot take hormone therapy due to conditions like breast cancer, or who prefer not to due to side effects, these findings offer more than just options — they offer evidence.
The researchers acknowledge that many earlier studies were small and not always rigorously designed, meaning clinicians stop short of formally recommending these therapies. But as the review makes clear, absence of perfect evidence isn't the same as evidence of absence. For women like Helen, it's a start.
