Persian Medicine is a traditional system of healing that has roots in ancient Persia, now modern-day Iran. It combines elements of herbal medicine, dietary practices, and holistic approaches to health. This system emphasizes the balance of the body's four humors: blood, phlegm, yellow bile, and black bile, which are believed to influence physical and mental well-being. Practitioners of Persian Medicine often use natural remedies derived from plants, minerals, and animal products. Notable figures in this field include Avicenna, a Persian polymath whose influential work, the Canon of Medicine, laid the foundation for medical practices in both the East and West.
