During the Golden Age of Arabic Medicine and the translation movement, many advancements were made in regard to medicine and pharmacy. These developments stemmed from the mindset that for every ailment that is inflicted on man, God creates a cure in nature. This thought process was termed pharmacognosy. Books were one of the main ways people studied different drugs. Most books on pharmacology were not originally Arabic, but were Greek. Some of the books that impacted the field were Tarkib-Al-Advieh about mixtures of drugs, Al-Advieh Al-Mofradeh which was written about single drugs, Ghova-Al-Aghzieh which concerned the potency of food for medicine, Al-Advieh Ao Al-dava, Al-Oram which concerned swellings of the body, and Al-Teriagh or The Book of Theriac. Through readings, Islamic doctors were able to find drugs that they could use to help treat patients.
