Taking herbs on your own increases your risk, so it is important to consult with your doctor or pharmacist before taking herbal medicines.
Used correctly, herbs can help treat a variety of conditions, and in some cases, may have fewer side effects than some conventional medications. Never assume that because herbs are "natural," they are safe. Some herbs may be inappropriate for people with certain medical conditions. Because they are unregulated, herbal products are often mislabeled and may contain additives and contaminants that are not listed on the label. Some herbs may cause allergic reactions or interact with conventional drugs, and some are toxic if used improperly or at high doses. Taking herbs on your own increases your risk, so it is important to consult with your doctor or pharmacist before taking herbal medicines.
