Scientific practice has proved that appropriate intensity of the electric field has a favourable impact on human body cells. Based on this biomedical theory, high potential thepeutic equipment place people in the high voltage low frequency alternative electric field, then the body cells, body fluid, nerves would discharge silently affected by the electric field; the combined effect of air ion flow and ozone put the body zwitterion and electric doublet in a right order according their nornal valu.
