Ricinus communis The poison in castor seeds is a protein called ricin (RYE-sin), which is one of the deadliest natural poisons. It is 6,000 times more poisonous than cyanide and 12,000 times more poisonous than rattlesnake venom. One millionth of an ounce (0.035 milligram, or 4 seeds) can kill an adult male. Castor oil is produced by cold pressing the seeds followed by heat. Since ricin is water soluble, the oil contains very small amounts and heating ensures it is removed. Almost all of the ricin remains in the leftover dried castor bean cake. The botanical name of the castor bean or castor oil plant is Ricinus communis. It is a perennial in the Euphorbia Family (spurge) which are known to contain latex-like sap but the sap of the castor bean is more water-like.
