This guide is educational information about herbs and dietary supplements — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor or pharmacist. It does not diagnose, treat, cure, or prevent any condition. Dietary supplements are not evaluated by the FDA the way medicines are, quality varies between brands, and some herbs and supplements can interact with medications or be unsafe in certain conditions. Talk to your doctor or pharmacist before starting any supplement — especially if you are pregnant or nursing, take prescription medication, have a health condition, or are due for surgery. Individual results vary. Seek urgent care for any severe reaction, and in an emergency call 911.
