Ayurveda (meaning 'science of life' in Sanskrit) is the ancient Indian system of medicine and health. While it's technically an Upaveda (supplementary text) derived from Atharvaveda rather than one of the four main Vedas, it's the only option directly focused on health and cure. The four Vedas are Rigveda, Yajurveda, Samaveda, and Atharvaveda.
