We can distill the tiny chunks he needs to know. He does not need to know all the science behind allergic responses.

He needs to know:
-------------------------
-- This is not a fluke: you will react to further mango exposure.
-- You must be kept safe from further exposure.
-------------------------
-- The allergen in mango peel, called urushiol, rapidly contaminates materials it touches.
-- It is unsafe for you to have *any* exposure to mangos as well as surfaces, cloth, skin (his), that might have touched them even momentarily.
-------------------------
-- He can decontaminate exposed materials by immediately washing them with soap and water.
-- Skin is only decontaminated by 50%, at most.
-------------------------

That should be enough to put him on the right track.

Do you think he can "tolerate" that amount of text?

Next question, would he have a problem "believing" this stuff without viewing the references? If need be, we could give references but it's hard to find references that aren't text.

=============

I looked for diagrams but kept finding things on the allergic immune response; none covered progressive sensitization over time. One article expressed this concept with numerical data but within the text. Also, it was not a formal study and the number of people involved was small.
