Thanks, all. Zuliekaa is right, I would have done a poll if I'd thought about it. But the impression I'd gotten from the Big OoO Thread is that everyone else is like me...we don't want to give it up.

I've been researching this issue, found this:

"according to the book Beyond Antibiotics: Healthier Options for Families, is that bacteria do not develop resistance to oregano oil."

and this!:

"Oregano had 3 to 20 times higher antioxidant activity than the other herbs studied."

You can read the whole thing, here:

I think I'll keep going and see what happens, maybe taper off the doses when I stop seeing changes...which hasn't happened yet. This is my second day with the OoO in my shampoo, and a friend said my hair looks "softer and fluffier."

Egads! This stuff is so cool!
