To simplify information search in the sphere of phytotherapy literature sources are divided into five groups in accordance with their value decrease: scientific and traditional (professional) phytotherapy, quackery, folk, pseudofolk and pseudoquackery practice. It is proposed to divide the traditional phytotherapy sources into three groups: 1) survived schools (Chinese); 2) lost schools (Mesopothamian, Old Greek, Old Egyptian, Old Indian); 3) mixed schools (Roman, French, Swiss, Arabic, Tibetian).
