The deadly poison, Ricin, is produced from which plant?
Ricin Ricin Ricin ( ), a lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant, "Ricinus communis", is a highly potent toxin. A dose of purified ricin powder the size of a few grains of table salt can kill an adult human. The median lethal dose (LD) of ricin is around 22 micrograms per kilogram of body weight if the exposure is from injection or inhalation (1.78 milligrams for an average adult). Oral exposure to ricin is far less toxic as some of the poison is inactivated in the stomach. An estimated lethal oral dose in humans
Wood Green ricin plot There was no UK poison cell linked to al Qaida or Muhamad al Zarqawi. There was no ricin with which to poison London, only notes and 22 castor seeds . There was no one who even knew how to purify ricin. On 17 August 2006, Craig Murray summed up on "CounterPunch": I spoke at the annual Stop the War conference a couple of months ago [and] referred to the famous ricin plot... It was alleged that a flat in North London inhabited by Muslims was a "Ricin" factory, manufacturing the deadly toxin which could kill "hundreds of thousands of people".
