    Yes, Ricinin is a deadly poison to human being. It is found naturally in castor beans. It has also been reported that a dose the size of a few grains of table salt can kill an adult human.

    Ricin is a protein that is naturally found in castor beans (Ricinus communis). It is so powerful a poison that the US Centers for Disease Control (CDC) estimate the lethal dose in humans is about the size of a grain of salt (500 micrograms injected or inhaled).Ricin inactivates the ribosomes in cells making them unable to produce proteins. Cells need these proteins to survive and reproduce, so when ribosomes are inactivated, cells die.
