Abstract

A method for treating living tissues and/or cells consisting essentially of electromagnetically inducing in the tissues and/or cells alternating pulsating electrical signals having a wave form which comprises a positive portion with a duration of between 1 and 3 milliseconds, and a negative portion having a peak value less than that of the positive portion, followed by a region of exponential extension tending to the reference value zero.
