The preparation of a compress using castor oil involves saturating a piece of flannel with the oil and applying it to the skin. This is typically covered with a layer of plastic and a heat source, such as a hot water bottle, to enhance absorption. The process aims to facilitate the therapeutic properties of the oil through topical application and heat-induced penetration.
Throughout history, topical applications of castor oil have been employed for various wellness purposes. Proponents suggest benefits including support for detoxification processes, soothing inflammation, and promoting circulation. While anecdotal evidence exists, scientific validation of these benefits remains an ongoing area of investigation.
