Durable, reusable and highly absorbent, Heritage Store Wool Flannel holds the right amount of oil to create a soothing castor oil pack wrap. Recommended by alternative healthcare practitioners to support overall health and wellness, castor oil packs are among the most popular alternative medicine products around and can be used for a variety of reputed health benefits. To use a castor oil pack, simply fold Wool Flannel fabric into the appropriate size for the area you are treating, then saturate the flannel cloth with Heritage Store Organic Castor Oil (not included). Apply flannel to abdomen, joints or other desired areas, cover with plastic wrap, then apply mild heat by placing a heating pad on top.** Rest for an hour or longer to let this nutrient-rich oil be absorbed by your skin and use this down time to meditate, read or just relax. Our Wool Flannel is reusable, comfortable, and made without causing harm to animals.
