Dong Quai for Menstrual Health

Research suggests that Angelica sinensis (dong quai) has a long history of use in traditional Chinese medicine for menstrual and gynecological health, and the available evidence — drawn largely from reviews, laboratory studies, and animal research rather than large-scale human clinical trials — indicates that its bioactive compounds, including ferulic acid, ligustilide, and polysaccharides, may contribute to anti-inflammatory, antispasmodic, and antioxidant effects relevant to menstrual conditions. Studies indicate it is among the most frequently cited plant remedies for menstrual disorders across multiple world regions, and a meta-analysis of TCM formulas for antipsychotic-induced amenorrhea found high rates of menstrual restoration in studies where dong quai was commonly included, though the authors of that analysis acknowledged the need for more rigorous investigation into mechanisms and study quality. The evidence is mixed in important respects: findings come predominantly from traditional use documentation, in vitro research, and animal models rather than well-controlled human trials, and a 2016 review highlighted the absence of standardized quality control criteria for dong quai products, meaning potency and purity can vary considerably across commercially available supplements. Safety concerns also appear in the literature, including a documented case of a clinically significant interaction with warfarin and cautions about increased photosensitivity, underscoring that while the research direction is generally supportive of its traditional applications, meaningful gaps remain and independent evaluation of the evidence is warranted before drawing firm conclusions.
