There are a lot of woods that cause allergic reactions ,here is an article and list : http://www.wood-database.com/wood-ar...-and-toxicity/
I had an allergic reaction last winter,with the rash and itchy skin,my face swelled up to where I could hardly see.Went to the doctor,went through allergy testing and they could not determine what caused it.I always thought it was from wood,so stayed out of the shop for a month and it all cleared up.But since I have noticed when i work with western cedar and walnut,I get itchy.I now own a Trend Airshield Helmet and a turners smock that covers me right up to my neck.
