Grr.

Anyone happen to know whether or not shea butter is counted as an allergen under the category "tree nuts"? Wonderful Husband is highly allergic to tree nuts (as in, they will land him in the hospital or kill him) and I bought some soap (which, granted, only I would use) with shea butter in it. It doesn't have a warning on it (though, granted, it's not a food product) and NOTHING I can find on the internet will give me a solid yes/no as to whether it's an allergen in that class or not... but I would rather be sure.
