Purvakarma is the first set of actions that are taken ahead of the Panchakarma therapy and may last for three to seven days. At this stage, the body is prepared for eliminative treatment by loosening the toxins and increased doshas in the body.
The cause of diseases is amam, or undigested toxins that get formed in the system due to external factors, and spread to different parts of the body. Through Purvakarma these toxins are channelized and collected for easy removal at the Pradhanakarma stage.
Important Purvakarma techniques regularly used across the Pentads of Panchakarma are Pachana (digestion), Snehana (oleation), and Swedana (sudation). They prepare the body for detoxification and revitalization. Panchakarma treatment is impossible without Purvakarma.
