Are there any herbal supplements that cause post-surgical bleeding?
This is the most important group of supplements that need to be discontinued prior to surgery. The herbs that cause that are the herbs that act as anticoagulants, which need to be discontinued so that there is not excessive intraoperative and, as important, postoperative haemorrhage. The herbs that begin with the letter “g” classically have anticoagulant properties. Those would be garlic, ginseng, gingko, and goldenseal. Another herb that has anticoagulant properties is feverfew. In addition, vitamin E is well known to have anticoagulant properties and should be discontinued prior to surgery.
