Castor oil is obtained from the beans or the seeds of the castor oil plant or Ricinus communis. It is a thick, colorless or pale yellow-colored oil. This oil has been in use for centuries in many parts of the world like India, China and Egypt for alleviating a number of health conditions.
It is a triglyceride of fatty acids, out of which ricinoleic acid, oleic acid and linoleic acid are the main components, which account for most of the medicinal properties of this oil.
