Which complementary therapies can help patients with PMS?

Abstract

Chasteberry tree and calcium have demonstrated efficacy and safety in treating symptoms of premenstrual syndrome (PMS) (strength of recommendation [SOR]: A, randomized controlled trials [RCTs]). Pyridoxine and saffron may be effective, but high doses of pyridoxine can cause neuropathy (SOR: B, RCT and meta-analysis of lower-quality studies). Insufficient evidence exists to recommend magnesium. St. John's wort and evening primrose oil aren't effective for managing PMS (SOR: B, inconsistent or limited quality patient- oriented evidence). No evidence was found to support black cohosh or vitamin E.
