Buckwheat
(Fagoypyrum esculentum)

Poisonous to Horses

Toxic parts and chemical: all parts of dry or
fresh buckwheat contain fagopyrin.

Symptoms of Poisoning: photosensitive
dermatitis results from fagopyrin in the
bloodstream that interacts with ultraviolet
rays of the sun. Skin will slough off in severe
cases. White skinned horses can have more
severe cases.

If given antihistamines and anti-inflammatory
medications as soon as symptoms appear
the progression will be less severe.
