  • Interesting fact: Ricin is a protein produced by the castor oil plant, Ricinus communis, which is highly toxic (the minimal lethal dose is around 1 µg / kg body weight, that means 1/15th of a milligram could kill a 150 lb. person). Ricin can be a dangerous contaminant, making the production of castor oil a precisely controlled process.
