White Peony Root for Menstrual Health

Research suggests that white peony root (Paeonia lactiflora) and its key compounds, particularly paeoniflorin and albiflorin, have demonstrated analgesic and anti-dysmenorrhea effects across a range of preclinical studies, including multiple animal models of primary dysmenorrhea, and the evidence is consistently supportive in direction across all twelve reviewed sources. Studies indicate that these effects are most frequently observed when white peony is used as part of traditional Chinese medicine multi-herb formulas such as Guizhi Fuling capsule, Taohong Siwu decoction, and others, making it difficult to isolate the specific contribution of white peony root alone. The body of evidence draws primarily from experimental animal studies, ethnopharmacological surveys, and traditional use documentation, with only one randomized controlled trial identified, which examined a combination formula rather than white peony in isolation, meaning the clinical evidence in humans remains limited. Comprehensive reviews published in 2021 and 2024 corroborate the long history of use for gynecological complaints including dysmenorrhea and amenorrhea, but more rigorous human clinical trials focused specifically on white peony root would be needed to draw firmer conclusions about its standalone effectiveness.
