Synopsis

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

Dong quai (Angelica sinensis) is a traditional Chinese herbal remedy that has historically been used to support women’s reproductive health, including symptoms associated with premenstrual syndrome (PMS). Specifically for PMS Type S, which is characterized by symptoms of swelling and bloating (often attributed to excess estrogen or estrogen dominance), dong quai has been included in traditional formulas to help "move blood" and alleviate stagnation. In traditional Chinese medicine (TCM), dong quai is valued for its supposed ability to regulate menstrual cycles, relieve menstrual cramps, and reduce symptoms associated with hormonal imbalances. However, the evidence for its effectiveness in treating PMS Type S is primarily based on anecdotal and traditional use rather than robust clinical trials.

From a scientific perspective, there are only a few small studies and some laboratory data suggesting dong quai may have mild estrogenic or antispasmodic effects, but these findings are inconsistent and not specific to PMS Type S. Most well-designed human studies have not confirmed significant benefits for PMS. The evidence rating of 2 reflects that while there is a strong tradition of use, scientific validation is weak and not specific to the subtype of PMS marked by swelling. Most modern clinical guidelines do not recommend dong quai as a primary therapy for PMS, though it is still used in herbal medicine practice, particularly within the context of multi-herb formulas in TCM.
