There are two ways of treating the sick individual. One is by the law of opposites and the other is by the law of similars. Homeopathy works on the law of similars. Simply put, this means that a medicine, which can produce sleeplessness in a healthy individual can cure the complaint of sleeplessness in a sick individual. And a medicine that can produce diarrhea in a healthy individual can cure a person suffering from diarrhea. Taking the medicine stimulates and enhances the body’s own mechanism to fight the disease. It corrects the body’s immunity, which in turn fights the disease.
