Even the shavings (if they are just stood on) can kill a horse. I sugest doing to reseach on this, as there are a lot of poisonous plants.

Since your horse can't tell you in words you will have to pay close attention to non-verbal symptoms. If he has eaten something that has caused a reaction you may see swelling around the face, jowls and/or throatlatch area. He may drool, look lethargic or may be off his feed. If the irratent is external look for localized swelling, hives, itching, ect. If you are worried call your vet and ask for advice. Better safe than sorry.
