This study aimed to detail the pattern of complementary and alternative medicine (CAM) used by women with cyclic perimenstrual pain and discomfort (1). The study used a survey of over 7000 women with various female health conditions and looked at how frequently they saw their CAM practitioners. The results showed that endometriosis was 3.7%, PMS was at 41.2%, irregular bleeding was at 22.2%, heavy periods at 29.8% and severe period pain at 24.1%. Women with endometriosis were more likely to consult a massage therapist or acupuncturist and to have used vitamins, yoga, or Chinese medicine. PMS were more likely to consult osteopaths, massage therapists, naturopathic doctors or herbalists. The authors conclude that there's a high prevalence of perimenstrual pain among women in the mid-thirties age group. Women used CAM differentially when they had specific symptoms. Use of CAM needs to be properly assessed to ensure safe and effective use.
