Topical irritation isn't indicative of a systemic reaction to an
allergen, which is what anaphylaxis is. I have a pretty severe skin
reaction to morado (the aforementioned "bolivian rosewood") but it
causes no other allergic reactions whatsoever, and I am an asthmatic.
AAMOF, the only thing I've ever turned that gave me any breathing
difficulties was some bone-dry birch, which actually just made my
throat sore.

It's been a while since professional school, but I seem to recall that skin
sensitivity testing is predictive of the potential for systemic
hypersensitivity. Your experience, while encouraging, may not be
conclusive. I'd use caution around those substances to which you react.
