Satratoxin-H

Satratoxin-H, a trichothecene mycotoxin, is a naturally occurring toxin produced by the ascomycetes "Stachybotrys chartarum" and "Podostroma cornu-damae" which is toxic to humans and animals. The clinical condition it causes is known as "Stachybotrotoxicosis". It is related to the mycotoxin T-2, but unlike T-2 has not been reported to have been used as a chemical weapon.
Properties.
Satratoxin-H is almost completely insoluble in water, but is easily soluble in lower alcohols and polar solvents such as ethanol, methanol, 2-propanol, acetone and chloroform.
Satratoxin-H is not officially classified as a chemical weapon. 
Effects.
Satratoxin-H is extremely versatile. Contact with the solution through ingestion, inhalation, or even physical contact produces symptoms similar to those listed below.
However, if consumed in large quantities, it can be lethal. Satratoxin-H has little effect on bare skin, and does not blister it in the way many chemical weapons do. However, upon contact with sensitive surfaces (eyes, interior of mouth or nose), inflammation will occur.
Satratoxin-H has an for mice of 1.0-1.4 mg/kg, upon injection. Otherwise it is reported to be about five times as toxic as T-2.
