Ricin is a poison found naturally in castor beans, the same substance used to make castor oil.

The deadly substance is found in the outer covering, hull, of the bean which is native to tropical east Africa around Ethiopia.

Castor beans are not dangerous on their own because they are surrounded by an indigestible capsule.  

It can be found as a powder, mist or pellet or it can be dissolved in water or weak acid. It is very difficult to trace.

The pulp of around eight beans can kill an adult and a dose of purified rich powder, the size of a few grains of table salt, can cause death. 

Ricin works by getting inside the body’s cells and preventing them from making the proteins they need – and without them, cells die.

Eventually this is harmful to the whole body and can cause death. But the effects of ricin poisoning depend on whether it was inhaled, ingested or injected.

It can take up to a day after exposure for symptoms to show up but it can kill you within three days.   

When inhaled, symptoms include difficulty in breathing, fever, cough, nausea, sweating and tightness in the chest. Death occurs after blood pressure plummets and breathing stops.

Metropolitan Police arrested six suspects on January 5 2003 with another arrested two days later. 

The Biological Weapon Identification Group in Wiltshire identified there was no trace of ricin. 

However Kamal Bourgass was sentenced to 17 years imprisonment on the basis of five pages of handwritten notes in Arabic of how to make ricin, cyanide and botulinum and a list of chemicals used in explosives. 

Iraq admitted to the United Nations Special Commission that it manufactured ricin and tested it in artillery shells before the Gulf War which took place between 1990 and 1991.
