Herbal medicines are medicines that contain active ingredients made from plant parts such as leaves, roots, and flowers. However, just because something is “natural” does not necessarily mean it is safe to consume. Like traditional medicine, herbal medicine can affect the body and can be potentially harmful if not used correctly. Therefore, they should be used with the same care and respect as conventional medicines. If you need to talk to your doctor or pharmacist about a health problem or surgery, be sure to tell your doctor that you are taking herbal medicine.
