This doesn't sound like anything that normally happens with oxalis, unless 
he has an extreme allergy to it.  Of course the same thing could happen with 
peanuts or shrimp in someone else.  What it *does* sound like is something 
that would happen if he got a piece of some aroid - do you have any arums, 
callas, caladiums, arisaemas, or other related plants in the area?  Those 
plants have calcium oxylate crystals throughout their tissues which when 
eaten uncooked, produce exactly the kind of symptoms you describe.   Almost 
immediate stinging pain and swelling.  Taro will do it if you try and eat it 
raw, too.
