Queen of the Thrones® made this ancient self-care practice easy with the original heatless, less-mess, reusable Castor Oil Pack. Designed by a naturopathic doctor, the Liver Pack is made with an inner 100% organic cotton layer that touches the skin, an outer less-mess layer of polypropylene, and stretchy, adjustable straps made from nylon. No uncomfortable buckles, buttons or itchy velcro, your Castor Oil Pack for Liver is comfortable enough to sleep in and wraps around your body like a nice warm hug. Castor Oil Packs worn on the liver area are thought to support less stress, deeper sleep, inflammation balance, liver detox, lymphatic drainage, colon cleansing, hormone balance and more.
