For six centuries, Avicenna's Canon of Medicine was the most studied medical text in the world—the authoritative guide for physicians from Persia to Paris. Written around 1025 CE by the great philosopher-physician Ibn Sina, it organized all of ancient and medieval medicine into a single, luminous system: the four elements and temperaments, the humors that shape health and illness, the art of diagnosis by pulse and urine, the discipline of diet and regimen, and a vast pharmacopeia of natural remedies. This modern-English edition makes the Canon's essential teachings accessible to today's readers for the first time in clear, inviting prose. Faithful to the original's meaning and spirit, it distills the five books of the Canon into a readable journey through the foundations of medicine, the care of the body, and the physician's art. Whether you come as a student of history, a seeker of holistic wisdom, or a reader curious about how an age of genius understood the human body, this edition offers a timeless vision of health as balance.
