The Canon of Medicine (original title in Arabic: القانون في الطب "Al-Qanun fi al-Tibb") is a 14-volume medical encyclopedia by the Persian Muslim scientist and physician Ibn Sīnā (Avicenna) in the 1020s. Written in Arabic, the book was based on a combination of his own personal experience, medieval Islamic medicine, the writings of Galen, the Indian physicians Sushruta and Charaka, and ancient Arabian and Persian medicine.[1] The Canon is considered one of the most famous books in the history of medicine.
Also known as the Qanun, which means "law" in Arabic and Persian, the Canon of Medicine remained a medical authority up until the 18th century[2] and early 19th century.[3] It set the standards for medicine in Europe and the Islamic world, and is Avicenna's most well-renowned written work. The principles of medicine described by him ten centuries ago in this book, are still taught at UCLA and Yale University, among others, as part of the history of medicine. Among other things, the book is known for the introduction of systematic experimentation and quantification into the study of physiology,[4] the discovery of the contagious nature of infectious diseases,[5] the introduction of quarantine to limit the spread of contagious diseases, the introduction of experimental medicine, evidence-based medicine, clinical trials,[6] randomized controlled trials,[7][8] efficacy tests,[9][10] clinical pharmacology,[11] and risk factor analysis, and the idea of a syndrome in the diagnosis of specific diseases.[12]
