Synopsis

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

Puerarin is an isoflavone compound extracted primarily from the root of Pueraria lobata (Kudzu), a plant widely used in Traditional Chinese Medicine (TCM). Its use for menopausal symptoms is mainly rooted in tradition, as Kudzu root has been historically prescribed to manage a variety of conditions, including those associated with female hormonal changes. The traditional rationale is based on the phytoestrogenic properties of isoflavones like puerarin, which are thought to exert mild estrogen-like effects in the body and help alleviate symptoms such as hot flashes and mood swings.

Scientific studies on puerarin for menopause are limited and generally of low methodological quality. Some preclinical and small-scale human studies suggest that puerarin may mimic some actions of estrogen, potentially offering relief from vasomotor symptoms. However, robust clinical trials are lacking, and systematic reviews often highlight insufficient evidence to recommend puerarin as an effective or safe treatment for menopause. Most authoritative guidelines do not endorse its use for this indication.

In summary, puerarin’s use for menopause is primarily traditional, with its application based on historical practices and theoretical estrogenic activity. The scientific evidence supporting its efficacy and safety remains weak and inconclusive.
