I'm alergic to Cocobolo, ebony, bocote, cedar, yew, and I'm sure I'll find others. Just the dust when I'm sanding/grinding; I have dust collection, / resipatory protection, the good rubber jobs with the changable carts... but...
Ebony, pretty much shuts off my windpipe like easy off oven cleaner does to me. I hate the stuff.
Cedar, gives me severe nasal itching, sneezing, but I like the smell so much I use it, it's worth it.
Cocobolo gives me etreme excess nasal mucus production to the point I nearly drown in it. But it's pretty and cutting it really greases up the wheels of my band saws.
Bocote same as cocobolo,
Yew, dust makes me sneeze uncontrolably, make my eyes well up (not because it smells so good it brings tears to my eye either) and makes my skin itch.
Bolivian rose wood almost like cocobolo just not as bad.
Weird stuff, I'm telling you.
