When my son gets bit by mosquitoes and ants, he gets really big, angry red welts--every time. He got bit my a mosquito in the middle of his forehead (prime spot for scratching) and I immediately applied this comfrey salve. He only ever had a tiny red bump and it went away quickly. We've also used this on my burn (crazy toaster oven has it out for me) and my younger son's nasty I-was-running-at-the-public-pool-even-though-I-know-I-shouldn't elbow scrape. Now my kids ask for this salve whenever they have a boo-boo.
