The recent studies show that the most of the human somatic and mental disorders are caused by the imbalance of the folic acid in the organism. Most of the patients suffering from different illnesses (from the stomach ulcer to autism) lack folacine or folic acid, known as the pteroil-glutamic acid. It is an essential vitamin which is referred to the vitamin group B. Its other names are Bc or B9 vitamin and the Lactobacillus casei factor, but these terms became obsolete today. The modern term folic acid received from the Latin word “folium” which means “a leaf” because first it was extracted from the green leaves of plants in 1941. It is contained in all the organs and tissues of animals, plants, microorganisms and human bodies, which are however unable to produce it themselves. That’s why a human must consume it with food. In addition to that the folic acid doesn’t tend to be accumulated in the tissues of the body and its stock is to be supplied daily.
