Herbal medicine is an old method of treatment that makes use of herbs or substances obtained from them. For thousands of years, dozens of herbs have been used to treat minor health conditions. Today, many of the drugs that are prescribed or used by doctors are also derived from herbs. However, herbalists prefer to use these herbs in their natural, unrefined state because they believe that the side effects are equalized. For every bodily disorder, herbalists believe there is a corresponding natural remedy.
