Low dose medicine is a new therapeutic approach aimed at restoring physiology through communicating and signaling molecules such as cytokines, interleukins, growth factors, neuropeptides, neurotransmitters and hormones prepared in low dose-active homeopathic dilutions and therefore without any side-effects. Part one of the book covers in details each signaling molecule and its therapeutic application in low dose medicine, whereas part two offers a list of general treatment protocols for a variety of health conditions. The aim of this book is be at the same time a manual and also a compendium to my other books in describing possible different ways to restore a healthy condition without any side effects.
