Homeopathy has three principals or tenets. These principals are the rock bed of homeopathy. They have remained unchanged over the centuries, their truth continually re-demonstrated through successful treatment of the sick.

The first principal or tenet is similia similibus curentur which is a Latin phrase meaning likes should cure likes. Each person shows symptoms of his body, mind, and spirit, when he is sick. Some of these symptoms are common to the particular sicknesses and some of them are unique to that person in his sickness. The Homeopathic physician matches the symptom picture of the homeopathic remedy to the symptom picture of the person, with particular attention paid to those symptoms which are unique to that individual. Thus, for the homeopathic remedy to be curative, the symptom picture of the remedy must be like that picture which the sick person shows.
The second principal of homeopathy is the single remedy. It would be quite impossible for one to know which ingredient was doing what to a sick person if that sick person were given a medicine which was a combination of ingredients. Therefore, the homeopathic doctor only gives one medicine at a time to a sick person. The doctor allows sufficient time to pass to observe the effects of that medicine on the ill person.

The third principal of homeopathy is the minimum dose. Drugs given to people in material doses are frequently found to cause side effects or adverse reactions. To minimize this problem, the homeopathic doctor gives the smallest possible dose so as to maximize the beneficial effects and minimize the effects of the medicine.
