The Second Medicine, also called Ortho-Molecular Medicine, came into being with the invention of microscopes, especially the discovery of bacteria in the middle 18th Century. At that time, people discovered surprisingly that many diseases originally were caused by some microorganism and began to wonder how to prevent the germina entering human body.
