Homeopathy, which was developed in Germany by Dr. Samuel Hahnemann (1755-1834), uses extreme dilutions of elements which, when taken by a healthy person, cause similar symptoms to the ailment being treated. Such heavily diluted preparations are obviously very low in toxicity, with scarce side effects. Modern homeopathy uses a combination of remedies to stimulate organ function, induce drainage and detoxification, and provide cellular support. Classical homeopathy is built upon three principles: the above-described law of similars, the single remedy, and the minimum dose. An important part of prescribing a homeopathic medicine is a detailed patient interview to determine all symptoms being experienced. The physician then determines which medicine best matches those symptoms and prescribes a single medicine that covers all the symptoms, instead of a different one for each. This is the law of the single remedy. There are two parts to the principle of the minimum dose: first, the homeopathic physician prescribes only a very small number of doses and waits to see what effect it has; and second, the medicine is given only in infinitesimal doses.
