Premenstrual syndrome-commonly known as PMS-is a physical condition characterized by a variety of symptoms that typically recur during a particular phase of the menstrual cycle. Particularly every woman experiences at least one PMS symptom sometime in her life. Specific symptoms vary from woman to woman. Although some adolescents suffer from PMS, most women first develop the symptoms during their twenties.

Women most often affected by PMS are those who have experienced a major hormonal change, as may happen after childbirth, miscarriage, abortion, or tubal ligation. Women who stop birth-control pills may also notice an increase in PMS untill their hormone balance returns.

From traditional Chinese point of view, PMS suggests patient's "Qi," (pronounced "chee") and Blood were both week and stagnant.
