I had a EO blend from Soap Naturally that my son uses for a rash he gets every summer. It was lavender, patchouli & tea tree. I just went to find it and there's a picture but no recipe. I haven't made this in about 2 years and he's almost out, I'm sure I have it written down somewhere but we moved last year and I'm the most unorganized person I konw. Could anyone help me out?
