Ricin

Ricin is a highly toxic substance derived from the seeds of the castor oil plant, Ricinus communis. It disrupts protein production in cells, leading to cell death. Even a small amount can be lethal if ingested, inhaled, or injected. Ricin has been studied for its potential use in chemical warfare and bioterrorism, but it also has medical research applications. Symptoms of poisoning can include nausea, vomiting, abdominal pain, and organ failure. Due to its toxicity, ricin is considered a dangerous substance, and handling it requires strict safety precautions.
