What plant when exposed to causes loss of taste and smell?

Question

.

Answer 1

I am only finding causes such as sinusitis, allergies and certain medications. I am not seeing those symptoms listed for plants. Toxic reactions to plants are often vomiting and diarrhea. Of course the allergen plant ragweed causes allergy symptoms that if bad enough or becomes sinusitus could result in loss of taste and smell.
I looked at all the reactions to plants on poison.org and some other sites, but came up empty. You might try checking more sites that list poisonous plants such as the ASPCA.
