Avicenna was one of the most influential and renowned philosophers and scientists of the Islamic Golden Age. Often referred to as the "Father of Modern Medicine," he conducted pioneering research in various medical fields, including pharmacology and the use of herbal remedies, though not specifically aromatherapy as modernly understood. He is celebrated for his Aristotelian philosophy and contributions to medicine. Avicenna’s work spanned numerous subjects, including philosophy, astronomy, alchemy, geology, psychology, Islamic theology, logic, mathematics, physics, and poetry. He authored over 450 works during his lifetime, of which only about 240 survive. His most famous works include the Kitāb al-Shifāʾ (The Book of Healing), a comprehensive philosophical and scientific encyclopedia, and Al-Qanun fi al-Tibb (The Canon of Medicine), which became one of the most famous books in the history of medicine. The latter was used as a textbook in many medieval universities, including those in Montpellier and Leuven.
