No doubt, official medicine has reached great success in treating health problems and rescuing people from the claws of death. However, folk remedies on which nutritional supplements and vitamin() intake are modelled, must not be dismissed out of hands. Furthermore, today official medicine tends toward employing traditional folk methods of treatment in many situations. That is why nutritional supplements are so ingrained in an Eastern health regime, and why it is becoming increasingly popular to take vitamins in the West.

There was hardly a country in the world, the inhabitants of which did not use herbs and nutritional supplements() with medical aim and in everyday life: Greeks and Europeans, people of Ancient Rome and especially the inhabitants of China. Phytotherapy is the crucial constituent of folk medicine. It has a long history and broad experience. Hippocrates, whom we often call "the father of medicine", used more than 200 herbs and other natural nutritional supplements for treating different diseases. Not only health herbalists, but even ordinary people knew about the curative forces of many vitamin containing herbs and used them for keeping and restoring the normal body functions, for improving health to feel better and live longer.
