BRIEF: Are mimosa trees toxic to horses?

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.


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.
