In one of the earliest reported uses of bioterrorism, Rye Ergot (sclerotia) was used.  This happened as early as the 6th century BCE by the Assyrians against the Israelites.  This is generally regarded as the first case of bioterrorism.

 

The poisoning from ergot is called ergotism. The plant is infected with Claviceps purpurea which cause the health problems.

 

There can be either conclusive or gangrenous ergotism when poisoning has occurred.  In a conclusive case the body has convulsions, muscle spasms, hallucinations, and other symptoms.  In a gangrenous case, the victim may lose parts of their toes or fingers from gangrene.
