The process involves saturating a piece of flannel in castor oil and applying it to the skin, typically on the abdomen. A heat source, such as a hot water bottle or heating pad, is then placed on top of the flannel-covered area. This allows the oil to deeply penetrate the skin. Preparation includes gathering the necessary materials: castor oil, flannel, plastic wrap, a hot water bottle or heating pad, and an old towel.
Historically, the application of this method has been associated with promoting circulation and supporting the body’s natural detoxification processes. Proponents suggest that it may contribute to improved lymphatic drainage and reduce inflammation. The practice has been used in various traditional medicine systems for its potential therapeutic effects.
