Theophrast (371-287 BC) founded botanical science with his books “De Causis Plantarium”— Plant Etiology and “De Historia Plantarium”—Plant History. In the books, he generated a classification of more than 500 medicinal plants known at the time.[ 12, 13] Among others, he referred to cinnamon, iris rhizome, false hellebore, mint, pomegranate, cardamom, fragrant hellebore, monkshood, and so forth. In the description of the plant toxic action, Theophrast underscored the important feature for humans to become accustomed to them by a gradual increase of the doses. Owing to his consideration of the said topics, he gained the epithet of “the father of botany,” given that he has great merits for the classification and description of medicinal plants.[ 14, 15]
