What type of poison is derived from the castor bean?

Ricin is the correct answer because it is a highly toxic compound that is extracted from the seeds of the castor bean plant, scientifically known as Ricinus communis. This protein toxin interferes with cellular protein synthesis, leading to severe biological effects and potentially death, depending on the dose and route of exposure. The production of ricin involves the extraction of the beans, where it is found as a byproduct during the processing of castor oil.

Understanding the unique characteristics of ricin is important, especially in relation to its lethality, because it can be fatal if ingested, inhaled, or injected, even in very small quantities. The presence of ricin in the castor bean highlights its potential as both a natural poison and a biochemical weapon.
