Other than Oregano Oil about the only successful Essential Oil formula that sales for us is a formula I call Professional Animal De-Wormer. Basically is something I blended 15+ years ago for our cows. It is extremely super hot and meant to just ad to cow water or basically any mammal/bird, what ever...
An amishman 2 years ago tried it and decided to resell it. He sells so much that I must wonder who he is selling it to. He does have stories of how they cured their cows, etc.....but in general, farmers are not going to buy 2 ounce bottles of anything as their animal treatments. So I wonder if he is not actually selling it for humans.
ALL the same type herbs are used for any of the adult de-wormer formulas, just how hot or how strong, etc. determines how it can be used.
