I have tried it and it does an okay job. But it tastes terrible! And it lingers.

I use it for sinus infections - just a couple drops in nasal wash and it seems to help. But again...it tastes horrid!! AND...it burns.

I have to be really sick and miserable to take it. I've had much better luck with colloidal silver - which has no taste...and doesn't burn.

I never noticed the Oreganol doing anything to help my fibro. Just sinuses.
