Rating (out of 5): 2

Peony (Paeonia lactiflora), particularly its root, has a long-standing history of use in Traditional Chinese Medicine (TCM) for gynecological disorders, including endometriosis. In TCM, peony is known as "Bai Shao" and is often included in formulas intended to "nourish the blood" and "regulate menstruation." One of the most famous formulas, Toki-shakuyaku-san (Dang Gui Shao Yao San), combines peony with other herbs and has traditionally been used for symptoms such as pelvic pain, dysmenorrhea, and irregular menstruation—symptoms commonly experienced by women with endometriosis.

Preliminary laboratory studies suggest that compounds found in peony, such as paeoniflorin, may have anti-inflammatory and immunomodulatory effects, which could theoretically benefit endometriosis. However, robust clinical trials specifically evaluating the efficacy of peony or peony-containing formulas for endometriosis in humans are limited, and most evidence is anecdotal or based on small observational studies.

Overall, the use of peony for endometriosis is primarily justified by traditional use rather than strong scientific evidence. While some mechanistic and preclinical data are promising, more rigorous human studies are needed to confirm its safety and efficacy for this particular condition.
