Castor oil is a non-volatile fatty oil that is derived
from the seeds of the castor bean (Ricinus communis)
plant, aka castor
seeds. The castor oil plant belongs to the flowering
spurge family called Euphorbiaceae and is mainly
cultivated in Africa, South America and India (India
accounts for over 90% of castor oil exports globally).
Castor is one of the oldest cultivated crops, but
interestingly it contributes to only 0.15 percent of
the vegetable oil produced in the world each year. This
oil is also sometimes called ricinus oil. It’s very
thick with a color that ranges from clear to amber or
somewhat green. It’s both used topically on the skin
and taken by mouth (it has a mild scent and
taste).
