Isopathy  is a type of alternative treatment that is closely related to homeopathy. The difference between isopathy and homeopathy is that isopathy uses remedies that are made up from the cause of the disease. It is common in isopathy to give a product of a disease in an attenuated form (nosode) for the disease itself. For example, homeopathic preparation of Borrelia burgdorferi (microbe that causes Lyme disease) may be used to treat patients with complications of Lyme disease or Post-Lyme disease syndrome; homeopathic preparation of Herpes virus may be used to treat postherpetic neuralgia; homeopathic preparations of MMR or DPT vaccines may be used to treat conditions that followed vaccinations with these vaccines.
