Pre-Chemistry Concepts and Medical Therapy among the Ancient Physicians through the Pre-Socratic Philosophers

Chemistry as experimental science it began only in the seventeenth century, when it began to analyze the matter and its transformations with scientific method, moving away from being one of the alchemy doctrines. Previously the ancient pre-Socratic philosophy through observation for nature is concerned with the laws that govern it and the property of matter. Later the Hellenistic Alexandrian culture took possession of the Hermetic doctrines of the Egyptians, mixing them, with the pre-Socratic thought and Gnosticism. In this historical moment, therefore, there would have been a fusion between the Greek philosophical patrimony and the influences on medicine. The Hermetic gnosis evolved over time to become later in alchemy and then in the birth of chemical science. Many doctors are wandering philosophers who deal with cosmogony to understand the body and the diseases and discover new healing drug for treatment and thus they were the first chemist therapists.
