Castor oil

Castor oil is a thick, dense oil rich in ricinoleic acid, which has strong anti-inflammatory and antimicrobial properties. When applied to skin, it deeply penetrates and helps lock in moisture, making it useful for very dry areas like heels or elbows. It is also widely used in hair care because it supports scalp circulation, which may encourage healthier hair growth. Its thick texture makes it ideal for targeted treatment rather than full-body application. It is also used traditionally for soothing joint discomfort when massaged into affected areas.
