I searched at google under 'st. john's wort and pregnancy'.....It has a lot of info. From the little I read I would never take it when pg!! It causes increased uterine muscle tone (contractions), it interferes with anesthesia during childbirth, and it inhibits the body's ability to absorb iron. Iron is very important to mother and child during pregnancy. There are plenty of other, safe drugs your sister in law can take for depression during pregnacy. She is also playing russian roulette as to whether or not her baby/babies will have birth defects. Ask her if it is worth the risk?
