The only book explaining the scientific reasons for effective use of electrotherapy. It fills a gap in the popular health-related book selections by presenting clear interpretations of the latest research, backed up with easy-to-read charts and graphs. As the pharmaceutical choices for health care become more and more limited, treating only the symptom, the general bolstering of the immune system with electrotherapy is proving to have a well-spring of therapeutic benefits. There are many bioelectromagnetic (BEM) devices re-emerging in the 21st century, based on high voltage Tesla coils, that apparently bring beneficial health improvements to human organisms. The Tesla coil class of therapy devices constitute pulsed electromagnetic fields (PEMF) that deliver broadband, wide spectrum, nonthermal photons and antioxidant electrons deep into biological tissue. The results of this type of therapy are explained in the book with lots of references for further information.
