Herbal medicines are extracted from plants, have been used for generations, and have traditional and scientific evidence supporting their usefulness. They are effective in supporting the body’s innate capacity to heal itself and are often employed by naturopaths as part of a treatment strategy. Because they work on multiple levels for the body and mind, herbs can be an effective treatment for many illnesses and don’t have the usual harmful side effects, such as nausea, headaches, dizziness, depression and insomnia, that can accompany pharmaceutical drugs.
