ColoradoDove, I thought this was the most aggressive form of impetigo I'd ever seen, and treated it for WEEKS with tea tree essential oil. Slow healing, with more outbreaks. Once I added Wild Mediterranean Oregano to the mix (a few drops in the oil mixture applied topically, plus giving the children the oregano internally), we began to make progress. When my husband contracted it, he refused to wait for treatment and went to the doctor, where he discovered that it wasn't impetigo, but rather MRSA! Later, when I told our pediatrician about the experience, she couldn't believe I'd treated it successfully at home. I did put some of the prescription antibiotic cream on the sores that remained at that point (some had them in their noses). If you Google MRSA, you will find that it can be deadly, and for that reason, I think that if I had it to do over, I probably would've taken them to the doctor.
