castor oiln.

/ˈkɑːstərɔɪl//ˈkastərɔɪl/

Etymology: Origin of name uncertain: it has been suggested that this oil actually took the place of the drug castor , or perhaps of oil of castor (see castor n.¹ 5), in use in midwifery, etc., and thus popularly assumed its name.

A pale yellow oil obtained from the seeds of Ricinus communis or Palma Christi (family Euphorbiaceæ), having a nauseous slightly acrid taste; used in medicine as a purgative, and in some parts of the world in lamps.
