Thakradhara (from Sanskrit takra = buttermilk, dhara = flow) is a Panchakarma sudation therapy involving the continuous, rhythmic pouring of medicated buttermilk—often infused with cooling herbs—over the forehead (or entire body) using a dhara pot. Typically preceded or combined with Abhyanga (oil massage), the treatment lasts 30–60 minutes per session over a course of 7–14 days (occasionally up to 21 days), as prescribed by an Ayurvedic physician. Buttermilk is prepared traditionally by boiling milk with herbs (like Musta), fermenting into curd, churning with herbal decoctions (e.g., Amalaki kwatha), and removing butter before application. During the session, the flow is maintained about 4–10 cm above the forehead, with eyes and ears protected and the patient resting supine on a droni. Post-therapy includes rest equal to treatment time, cleansing, and scalp care (e.g., Rasanadi choornam).
