Premenstrual Syndrome and St. John’s Wort

ChiroACCESS

August 17, 2010

St. John’s Wort (Hypericum perforatum) shows promise in aiding those suffering from premenstrual syndrome.  In a recent study from the University of Leeds researchers found that St John’s Wort was “statistically superior to placebo in improving physical and behavioral symptoms of PMS (p<0.05).”  Other outcomes of the study including hormonal assessments, anxiety, depression, and other variables did not improve significantly.  Another study of PMS-like symptoms among perimenopausal women found significant reduction in anxiety and hydration along with other outcomes using a combination of St. John’s Wort and chaste tree/berry (Vitex agnus-castus).  These additional studies from the last year will help pave the way for future research to isolate issues like dose, clinical prediction variables and underlying mechanisms for action.
