I used the Oreganol P73 by dropping it under my tongue 2-3 times a day and didn’t notice a difference in my health… at least not a significant difference. I purchased 2 bottles of the Oreganol and I plan to return the one that is unopened. I’m not sure if I will ever finish using the opened bottle, which is unfortunate because it wasn’t cheap. There are a lot of people on this forum who feel they have had success with the P73… it just didn’t work as well for me.
I had heard that the doTERRA oregano was a lot stronger but I figured I could use it the same way as the Oreganol. I was wrong! The first time I tried to put the doTERRA oregano under my tongue, it burned my lip pretty bad. BAD IDEA! I should have read up on how to use it first. So after learning my lesson the hard way, I started rubbing it on my feet. If you want to take it internally, you can put it into empty gel caps. I plan to do that once I have a chance to buy some gel or veggie capsules.
