BRIEF: Are mimosa trees toxic to horses?


QUESTION:
I am trying to find out if mimosa trees (especially the leaves, flowers and beans) are toxic to horses. I have just moved to Arkansas from the northeast and remember hearing somewhere that they were and these trees are everywhere around here! In and surrounding the pastures.

ANSWER:
If horses eat enough mimosa, their hair may fall out due to mimosine intake, and there are other toxic effects at other doses, I believe...Their seeds contain djenkolic acid that can lead to kidney damge in humans, not sure about horses.
