The authors of this study examined cyclic perimenstrual pain and discomfort and alternative medicine (1). Data on endometriosis, PMS, irregular periods, heavy periods, and period pain were collected over 7 years. The results showed prevalence rates of PMS and heavy periods increased, while prevalence rates of endometriosis, irregular periods, and severe period pain remained stable. The most common use of CAM longitudinally associated with the perimenstrual symptoms was use of vitamins/minerals, yoga/meditation, massage therapy, herbal medicine, and aromatherapy. The authors conclude that only the prevalence of PMS and heavy periods increased with aging in this sample of women. While overall use of CAM practitioner and self-prescribed products/therapies increased over time, CAM was chosen by women mainly to treat endometriosis and PMS.
