I take the Oregano Juice and Oil at the advice of my holistic dentist to boost my immune system. My experience is that it made me feel really good, and almost completely diminished the metallic taste and burning I have been experiencing in my mouth, but after several weeks of using it, I started getting some symptoms similar to yours. Gas, stomach pain, etc. so I stopped taking it for a little while and those symptoms were gone. I did attribute this to "die off", as I know you get worse before you get better. It's a natural antiseptic, etc. and I just figure that I am "SO" toxic, that the pain is from it trying to clean my gut out. So, now I take it for awhile or when I feel like I need an immune boost, and then I take a break from it. My husband still takes it most of the time, and it's great when you need a good night of sleep, it's really relaxing. On the nights that I take it before bed, I don't wake up in the night, I actually SLEEP.
