Black cohosh (20–40 mg daily) can reduce hot flash frequency by 26% and severity by 36%. Red clover isoflavones (40–80 mg daily) may reduce hot flash frequency by 2–3 per day. Evening primrose oil (500 mg–2 g daily) provides emerging evidence for hot flash relief and improved sleep quality.
Menopause brings hormonal shifts that cause hot flashes, night sweats, mood changes, and sleep disruption. While hormone replacement therapy remains the most effective treatment, several botanical supplements have demonstrated meaningful symptom relief in clinical trials for women who prefer non-hormonal options.

Black cohosh and red clover are generally well-tolerated and may be appropriate for women with mild to moderate symptoms or those who cannot use HRT due to breast cancer history or cardiovascular risk. However, they are typically less effective than HRT for severe vasomotor symptoms. The decision should be individualized with your healthcare provider.
Current evidence suggests black cohosh does not have estrogenic activity and does not stimulate breast tissue. The North American Menopause Society considers it a reasonable option for breast cancer survivors experiencing hot flashes. However, discuss with your oncologist before starting.
At standard supplemental doses of 40–80 mg/day, clinical studies have not shown clinically significant effects on thyroid function in euthyroid women. Women with existing thyroid conditions should have levels monitored and take red clover at least 2 hours apart from thyroid medications.
Most clinical trials evaluated these supplements for 3–12 months. Black cohosh is approved in Germany for up to 6 months of continuous use. Many women take these throughout the menopausal transition (average 4–8 years) with periodic reassessment. Annual review with your healthcare provider is recommended.
