A rapid rise in the use of herbal medications has prompted the American Society of Anesthesiologists (ASA) to warn that these products should be discontinued prior to surgery.
"Just because a medicine is called ‘natural' or ‘herbal' does not mean it is harmless or completely safe," said ASA President John B. Neeld, Jr, MD, last month. Neeld noted that a number of anesthesiologists have anecdotally reported observing substantial changes in heart rate or blood pressure in some patients who were taking herbal medications, notably St John's wort, gingko biloba, and ginseng.
