>I always give myself an overnight patch test to determine sensitivity to any suspected wood. I did this with the Amboyna burl shown in a recent picture post.
I make a saw cut somewhere on the waste part of the wood to get under any surface coating or oxidation, then create some sanding dust, put the dust on a bandaid, and then stick it to the soft skin on the underside of my upper arm and leave it there overnight. If there is a blister or a red spot the next morning, I can't use the wood. If there is nothing under the bandaid, I am good to go. For me, a red spot is an indication of respiratory sensitivity, and a blister is obviously skin sensitivity.
