Jamaican black castor oil

Jamaican black castor oil (JBCO) is made by roasting the castor beans before pressing, which carries roasted ash into the oil and gives it a dark color and smoky scent. It is commonly used the same ways as regular castor oil — on skin, scalp, and hair — with buyers choosing it mostly for tradition and texture preference. Claims that the ash makes it work better are marketing, not established fact; the honest differences are color, scent, and price.

Listings below are ranked by price per fluid ounce from current Amazon data. JBCO often costs more per ounce than plain cold-pressed oil, and bottle sizes skew small, so the per-ounce column matters here. Check labels for whether a product is pure JBCO or a blend, patch-test before use, and avoid applying to broken or irritated skin.
