Su Jok is one of the systems of correspondence of the body to the palms and feet. I am wondering is zapper actually stimulating acupuncture points according to Su Jok? All the time I suspect that the zapper actually doesn't eliminate any parasites, but is working more as immunostimulator... The success ratio to eliminate bacteria "in-vitro" is so low, that I really can not explain the good performance of zapper to some people (and of course complete failure to the others).
