This is a prospective randomized-controlled trial looking at the safety and acceptability of using Chinese herbal medicine in patients with primary dysmenorrhea. The research team hopes to enroll 100 patients, 50 of whom will be randomized to receive the herbal tincture and 50 who will receive a placebo tincture.
