Is Tea-Tree Oil supposed to sting? A LOT?!?!?

no tea tree oil does not sting, i've had experiences that it itches a bit after i put it on. you should only put on a drop or two no more. also you should always check first to see that you are not allergic to the oil. it should help with the rash, that's what it does, and if you are going to apply it again, make sure you only put on a drop or two on the rash.
