How long has electro therapy been in use?
In the 18th century, Benjamin Franklin started to use electro therapy in Europe where it was very popular; but at that time there were no theories supporting it. Through modern technology, scientists today have verified the benefit of electro therapy and have brought it to the rest of the world. Today in Japan, Korea, Europe, the United States, China, Taiwan, Hong Kong and other countries, electro therapy with its negative charge is currently in use in many hospitals and homes to prevent diseases and improve health.
