Castor oil is a vegetable oil derived from the seeds of the castor bean plant, scientifically known as Ricinus communis. It is known for its thick consistency and pale yellow color. The oil is rich in ricinoleic acid, which is believed to have various health benefits, including anti-inflammatory and moisturizing properties. In addition to its use in cosmetics and skincare, castor oil is often used as a natural laxative. It can also be found in some industrial applications, such as lubricants and biodiesel production. However, it is important to use it cautiously, as the seeds contain a toxic compound called ricin.
