When I was about 10 years old my mom discovered that she is allergic
to mangos. Mangos and poison ivy are in the same family, and both
contain urushiols that irritate some people. My mom broke out in a
poison ivy-like rash around her lips and on her hands from cutting
fresh mango. I've never had a problem with it, and never even reacted
to poison ivy until last summer (I think this might be in part
because I learned very early from my mom how to identify poison ivy
and thus avoid it because she's quite allergic to that too). I also
hardly ever eat mangos since they aren't local and are often expensive.
On Saturday morning I ate half of an enormous mango for breakfast. It
was delicious. On Monday morning, I felt a tingling on my upper lip
and by mid day I had bumps forming all across my upper lip. I thought
it was a cold sore, because I get those, but I don't get them on my
upper lip and usually I don't get them on my lip unless I sunburn my
face (it took me years to figure this out). I was diligently not
picking at it and I treated it intensively with that Abreva sore sore
stuff. Today I've noticed a few spots on my nose (fresh mango is messy).
Last night I bought a small, perfectly ripe mango for about 25 cents,
and I ate it this morning for breakfast. It wasn't until after I'd
eaten it that it occurred to me that I might not have cold sores at
all, but mango rash on my lip instead. So, I suppose I'll see what
happens over the next few days. I think I can still eat mangos as
long as I make sure to wash my hands and around mouth right afterwards.
