Vasti—also known as Basti—is a central Panchakarma purification therapy in Ayurveda. Deriving from Sanskrit kā bāsti (“bladder/enema”), it involves the administration of medicated substances (herbal decoctions, oils, ghee, milk, or other therapeutic fluids) via the rectal (or sometimes urethral/vaginal) route. Originally preceded by preparatory Abhyanga (oil massage) and Swedana (steam or fomentation), Basti aims to balance Vata dosha by cleansing the colon (its primary seat), mobilizing toxins (ama), and simultaneously nourishing tissues. Treatments utilize different Basti types—Anuvasana (oil/ghee), Niruha (decoction), Matra (small-dose oil), Karma/Kala/Yapana (varied schedules and volumes), and Uttara Basti (for urinary/reproductive tracts). Sessions are tailored in duration and frequency according to condition, typically for digestive, musculoskeletal, neurological, metabolic, gynecologic, and dermatologic imbalances. Qualified practitioners perform the procedure as self-administration is not advised.
