It is applied 13.56 MHZ high frequency oscillating current, a pair of external capacitive flat-plates are used to act on the human bodies, thus producing an 'accumulative' electromagnetic field, where has both AC electric and magnetic fields. The energy of the electromagnetic field will be absorbed by the tissue and converted into heat to enhance the blood circulation, improve the local tissue metabolism, reduces the stress in the muscles and connective tissues, increase leucocytic phagosytizing capability, regulate the bodies' immunity, so as to cure the sub-acute, chronic inflammation and tumors in the bodies.
