The castor plant, also known as the castor oil plant, is the source pf castor oil, a vitamin supplement and lubricant. It is also the source of ricin, a poison.
The poisonous substance in castor oil is ricin, a protein that causes death at cellular level, and can be fatal. See the link below.
Ricin is a proteinic cytotoxin derived from the common castor bean, Ricinis communis. Recovered from the meal of castor beans in the castor oil making process, ricin toxin is perhaps 1,000 fold less toxin that botulinum toxin. Ricin is most toxic if inhaled and least toxic if swallowed. It has the potential to be used as a chemical warfare agent.

Ricin is a poison derived from castor beans. It can be made from the waste material after processing (mashing) castor beans into castor oil. Although not as lethal as anthrax, ricin prevents cells from producing protein and can lead to death within 36 to 72 hours. In 2013, a Mississippi man, Paul Kevin Curtis, was arrested for sending ricin-contaminated letters to a Mississippi senator and President Obama.
