Electro homeopathy, Electro homoeopathy, or Mattei cancer cure is a derivative of homeopathy invented in the 19th century by Count Cesare Mattei. The name is derived from a combination of electro (referring to an electric bio-energy content supposedly extracted from plants and of therapeutic value, rather than electricity in its conventional sense) and homeopathy (referring to an alternative medicinal philosophy developed by Samuel Hahnemann in the 18th century). Electro homeopathy has been defined as the combination of electrical devices and homeopathy.
