Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Licorice root (Glycyrrhiza glabra) has a long history of use in traditional medicine, including Traditional Chinese Medicine and Ayurveda, for a variety of women's health concerns. Its use for hot flashes is primarily based on tradition rather than robust scientific validation. Historically, it has been included in herbal formulas to "cool" the body and support hormonal balance, especially in menopausal women experiencing vasomotor symptoms like hot flashes and night sweats.

The rationale for its traditional use is linked to its phytoestrogenic properties—compounds in licorice root can weakly bind to estrogen receptors and may help modulate hormonal fluctuations that contribute to hot flashes. Some small clinical studies and animal models suggest potential benefits, but results are inconsistent and the quality of evidence is low. For example, a few small randomized controlled trials have reported reductions in frequency and severity of hot flashes in menopausal women using licorice root extract compared to placebo, but these studies are limited by small sample sizes and methodological concerns.

Overall, licorice root is used traditionally for hot flashes and there is some preliminary scientific interest, but the evidence is not strong or conclusive. Safety is also a concern, as prolonged use can cause side effects such as hypertension and low potassium. Larger, well-designed clinical trials are needed to confirm any efficacy for hot flashes.
