A surgeon's guide to herbal supplements.

The use of herbal supplements has steadily increased in the United States over the last decade. Despite the increased awareness of alternative therapies by the government and lay public, many physicians do not ask their patients about their use of these alternative medications. In addition, many physicians are unaware of the possible side effects that may occur when a patient consumes these substances. Considering a number of these supplements have been associated with adverse reactions in the perioperative period, it is important for a surgeon to understand all of the herbs a patient may be taking. The purpose of this article is to discuss the growing trend of herbal use among surgical patients and give the reader some background on the most commonly used herbs.
