The word homeopahy comes from the Greek homoios (similar) and pathos (suffering or disease), and its basic idea is that “like cures like”, which means that an ill person can be treated using a substance that can produce, in a healthy person, symptoms similar to those of the illness. Homeopathy developed by the end of the 18th century in Germany, where it is still being practised. Homeopathy sees a patient as a whole on three levels: the mental one, the emotional one and the physical one. The therapy is based on an analysis of subjective symptoms. This means that it is the sum of all symptoms that makes up the patient’s disease and each case should be treated individually. The different substances used are to stimulate the body’s ability to cure itself.
