If you’re taking herbal dietary supplements such as echinacea, ginkgo, garlic, St. John’s wort and others, or even Vitamin E supplements, and you’ll be undergoing a medical procedure that will require the administration of anesthetics, be sure to let your doctor know what supplements you are taking. A lot of herbal supplements have side effects and drug interactions.
