Ayurveda is an ancient Indian system of medicine that views health as a balance between the mind, body, and spirit. It is based on five fundamental elements - space, air, fire, water, and earth - that combine to form three biological energies or doshas (vata, pitta, kapha), seven tissues (dhatus), and three waste products (malas) in the body. Ayurveda aims to achieve physical, mental, and spiritual well-being through lifestyle practices, herbal remedies, yoga, and meditation.
