Homeopathic medicines are prescribed based not on the disease the person is diagnosed with but on the unique ways in which the individual experiences his disease. In other words, homeopathic medicines, not a single symptom or label of disease, are prescribed based on the SYNDROME of various physical and psychological symptoms. Although the selection of the right homeopathic prescription is more complex than the use of standard drugs, or even many herbal preparations, the system of prescription which is customizable to the whole person is intellectually sound...
The premise behind homoeopathy is that disease symptoms are not just incorrect for the individual, but that their body's effort is actually to fight infection and/or to handle stress. Instead of using large doses of drugs inhibiting or suppressing the symptoms, a person is individually prescribed very small and specially prepared doses of medicines for the unique ability to cause similar overdose symptoms in the sick person. The medicine can support and improve your body's defenses by finding a medicine that matches the symptoms of the sick person.
