Castor oil packs & wraps

Castor oil packs are reusable cotton, flannel, or wool wraps that hold oil against the skin, usually worn over the abdomen or joints for an hour or overnight. They are a traditional practice that has recently gone viral, and much of the marketing around them — claims about the liver, hormones, fibroids, or cysts — is not supported by evidence. What you are actually buying is fabric, ties, and sometimes a starter bottle of oil, so compare on materials and what the kit includes.

Because packs are sold as items rather than by volume, this table ranks listings by price per item instead of per fluid ounce. Check whether oil is included, what the pack is made of (organic cotton and wool cost more than polyester blends), and how it fastens. Oil-soaked packs can stain clothes and bedding, and the same skin cautions apply: patch-test, and keep oil off broken skin.
