I thought it was important to start this thread so there will be a compilation of the scientific studies and information that point to the effectiveness of microcurrent threapies, such as zappers, blood electrifiers, etc. MicroCurrent Research Clinical Studies The effects of a small, pulsed DC electric field on ATP and cAMP levels in in vitro and in vivo systems Specific Zapper Study That is just a start...many many more are available, so It can not be said that there is no evidence...we are being flooded with new evidence everyday.
