Synopsis

Source of validity: Traditional
Rating (out of 5): 3

Peony (Paeonia lactiflora) has a long history of use in traditional Chinese medicine (TCM), particularly for women’s health and gynecological concerns. In TCM, peony root (often white peony, or Bai Shao) is commonly used to "nourish the blood" and "regulate menstruation," with its use frequently paired with other herbs such as licorice in the classic formula "Shaoyao Gancao Tang" for menstrual cramps and hormonal balance. Peony is believed to help relieve symptoms associated with irregular menstruation, dysmenorrhea (painful periods), and polycystic ovary syndrome (PCOS). Modern herbalists sometimes recommend peony (often combined with licorice) for similar indications. Scientific research on peony’s effects on the ovaries is limited but growing. Some studies, particularly those on the combination of peony and licorice, indicate potential benefits in managing PCOS symptoms, possibly through effects on hormone regulation, anti-inflammatory activity, and improvement of insulin sensitivity. However, most of this research is preliminary, involves small sample sizes, or is based on animal models. There is not yet robust, high-quality clinical evidence to fully validate these traditional uses, but the consistency of traditional usage and some promising early research support a moderate evidence rating. Further studies are needed to clarify peony’s mechanisms and effectiveness for ovarian health.
