This will be posted in the Library soon, but I thought it might be appropriate to put it here. I believe this list originated in American Woodturner Magazine.
Good site and info. Just abit more info and not sure if it can be included or just for random use, a very good link was provided in an earlier thread that went astray. It was posted by Alfred of Canada and it is a worthwhile site if interested. http://www.wood-database.com/wood-articles/wood-allergies-and-toxicity/
