The concept of tridosha, or the three doshas, is an ancient system of medicine that has been used to diagnose and treat illness for thousands of years. It is based on the theory that humans are made up of three fundamental elements: physical body, intelligence, and soul. The doshas are the bodily fluids that regulate our physical and mental states, and are believed to be influenced by our diet and lifestyle. The three doshas are vata, pitta, and kapha.
