Black castor oil is a thick, dark-colored oil that is derived from the seeds of the Ricinus communis plant. It has been used for centuries in traditional medicine to treat a variety of ailments, including hair loss, skin conditions, and digestive problems.
Black castor oil is rich in ricinoleic acid, a fatty acid that has anti-inflammatory and antibacterial properties. It is also a good source of antioxidants, which can help to protect the skin and hair from damage.
