What is the potential effect of ingesting ricin?

The ingestion of ricin can lead to severe internal bleeding, which is a significant and critical effect of this potent toxin. Ricin is derived from castor beans and works by inhibiting protein synthesis within cells, leading to cell death and severe damage to the gastrointestinal tract and other internal organs. This process can result in intestinal hemorrhaging, which manifests as internal bleeding.

The toxic action of ricin primarily targets the liver, spleen, kidneys, and intestines, causing significant cellular injury and a resulting systemic inflammatory response, which contributes to the risk of bleeding. The symptoms can be extremely serious and may lead to shock and even death if not treated promptly.

Other potential effects such as skin irritation or intestinal blockage do not encompass the severe nature of the threat posed by ricin, while immediate healing is unrealistic given the highly toxic nature of the substance. Understanding ricin's mechanism of action is crucial for recognizing why internal bleeding is a primary concern in cases of exposure.
