Oils play an important role in Ayurvedic healthcare by balancing vata dosha. They are used both internally and externally. Internally, oils are used as part of foods, oral medications like snehapanam, and procedures like nasya. Externally, oils are used for massages like abhyanga, procedures like sirodhara and parisheka, and filling body areas like karna puranam. Oil massage is especially important for relaxation and treating various musculoskeletal and neurological conditions. Daily oil massage is recommended as part of a healthy routine.
