Udwarthanam (also called Udvarthana or Udgharshana) is a vigorous Ayurvedic full-body powder massage performed in an upward direction against the hair growth, using warm, medicated herbal powders—optionally blended with oil or ghee based on individual constitution (Snigdha/Utsadana vs Rooksha). After warming the powders, the therapist applies them with firm strokes across the body for 30–60 minutes, typically over 7–14 days. It’s preceded by mild oleation and followed by a warm bath and rest. The technique emphasizes deep friction and increased tissue heat to stimulate circulation, lymphatic drainage, exfoliation, and metabolic activation.
