Mango and poison ivy are members of the same family. They both contain a substance called urushiol (yu-roosh'-ee-all) which causes those annoying blisters and itches in some people.
Mangoes contain much less urushiol. However, you could get a rash from a mango if you are very sensitive to poison ivy.
Don't stop eating mangoes and don't be afraid to try one - they are really good! If you have a weird rash on your mouth, though, be aware that like blogger Silent Rant you may be be able to say, "Hooray! It's not herpes!"
