Homeopathy is a system of medical therapy that uses very small doses of remedies. These remedies are prepared from substances found in nature. The classical homeopath chooses the proper remedy by following a special rule of nature. This rule is called the Law of Similars. This law states “like cure like”, or that a medicine can cure a sick person if it can cause similar sickness in a healthy person. For instance, if you peel an onion, your eyes burn, itch and water. You might also have a runny nose and begin to sneeze. If you had similar symptoms during a cold or allergy attack, such as a runny nose, watery eyes and sneezing, a homeopathic micro-dose of remedy Allium cepa (red onion) would help your body heal itself.
