For women suffering from pelvic and back pain associated with endometriosis (uterus growth), garlic may help. In an Iranian study published in the journal Evidence-Based Alternative and Complementary Medicine, half of a group of 60 women with the disorder were given 400 milligrams of garlic in tablets daily, and the others received a placebo. Over a span of three months, researchers found that the women taking the garlic tablets had significantly less pelvic and back pain, as well as significant reductions in discomfort during menstruation and sexual intercourse.
