Why is St. John's Wort a concern? [DrugPatentWatch.com 1]

St. John's Wort (Hypericum perforatum) is a popular herbal remedy for mild depression, anxiety, and sleep disorders.

How does St. John's Wort affect birth control?

Birth control pills work by altering the levels of hormones, such as estrogen and progesterone, in the body. When St. John's Wort is taken simultaneously, it can cause the Cytochrome P450 enzymes to break down these hormones faster, reducing their effectiveness. This may lead to the pill not being as effective in preventing pregnancy, and potentially causing an irregular menstrual cycle. [3]
