Ayurveda is the oldest system of traditional medicine in India. It is based on the concept of five elements (ether, air, fire, water, earth) and three doshas (Vata, Pitta, Kapha), which represent biological humors. Health depends on balancing these elements and doshas. Ayurvedic treatment aims to restore balance through herbs, diet, yoga, and lifestyle changes. Diagnosis examines the pulse, tongue, skin, and symptoms to determine which dosha is aggravated.
