Ricin is extractracted from castor seeds, which come from the ricin plant RICINUS communis.
A typical castor bean plant has an average of 1,300 seeds. On average one cup contains 500 seeds, weighs 130 grams, and may yeild up to 3 grams of pure ricin within the crude product.
Ricin toxin can be in the form of liquid or a "white powder." The "white powder" more commonly associated with the toxin is indicative of a pure product. Crude ricin powder may have discoloration due to impurities, but the particle size may still be within the respirable range.
Has anyone one had any emergencies runs with castor beans?
