Panchakarma is derived from two Sanskrit words Pancha meaning five and Karma meaning Treatment. The five main procedures that are termed as panchakarma are Vaman, Virechan, two types of Vastis- Anuvasana Vasti & Nirooha Vasti and Nasya. These procedures aim at eliminating the vitiated doshas from the body or detoxifying the body hence these procedures are also regarded as Panchshodhana.
Before carrying out theses Panchakarma procedures, it is important to purify the body with Snehana (Oleation) and Swedana (fomentation). Snehana means to lubricate the body internally and externally either by administrating the medicated ghrits orally or by the application of the medicated oils over the body. With this process the fatty substance reach the deeper tissues and loosen up the toxins stuck in the cells. Swedana is done after Snehana process where in the doshas are liquefied and brought into the koshtha in order to eliminate them by inducing either Vaman or Virechan.
