Electrohomeopathy-

also called Mattei cancer cure, is a 19th century invention of Count Cesare Mattei (1809-1896)  based on homeopathy developed by Hahnemann in the 18th century with the addition of the concept of "bio-energy content extracted from plants".  To contrast,  homeopathy uses extracts of plants, animals, and minerals.  It was popular in the late 19th century.  Mattei believed there was "electricity" in botanical extracts and made bold, unsupported claims for the efficacy of his treatments including treatment of cancer.  Mattei believed different biological extracts contained red, yellow, blue, green, and white electricity.  There were three journals of electrohomeopathy at the beginning of the 20th century but interest in this system has waned. According to electrohomeopathy, all diseases were due to changes of the blood or lymphatic system, and therefore remedies were broadly divided into two categories to be used in response to either blood or lymphatic disease.  Electrohomeopaths believe diseased organisms are far more sensitive than healthy organisms and changing the condition of the bodily fluids will work on the cause of the disease.  Mattei would select the plant extract that was extremely diluted, that contained the kind of "vegetable electricity" needed to cure.  Now electrohomeopathy is practiced predominately in Pakistan and India, but some immigrants bring it with them to the US. Interestingly, the electrohomeopaths believe a complex mixture is needed to cure disease contrasted to Hahnemann (the originator of homeopathy) who believed only one agent should be employed.   LEVEL OF EVIDENCE: There are no scientific articles in the National Library of Medicine regarding electrohomeopathy therefore its use is purely speculative, based on hope rather than on any proof of safety or efficacy.
