Following is a fantastic article showing that high dose vitamin C greatly improves the efficacy of antibiotics. Similarly, since Wild Oregano Oil is also an antibiotic, it too should be potentized if taken with high doses of vitamin C.
Shortly after the birth of my third child, Hugo, I had to go to the hospital and receive IV antibiotics for seven different bacterial infections, including pneumonia – even my blood was infected with 2 different kinds of pathogenic bacteria.
In case you’re wondering why/how this happened – no one really knows for sure. But, I had a cough/cold infection for the last 2 months of my pregnancy, but stupidly just assumed there was nothing I could take for it, since I was pregnant – I learned later that I could have taken intravenous hydrogen peroxide and inhaled glutathione. The other huge contributing factor was that I was absolutely petrified of having another child – Hugo was our “surprise!” baby as both Ian and I had decided we couldn’t physically handle the work load and sleep deprivation of another child – and then here we were having one. So I was VERY emotionally affected by this event. I didn’t know much about EFT (Emotional Freedom Technique) at that time, but if I had, I would have immediately booked with Annabel Fisher to address all these emotions before giving birth – and that would likely have prevented the infectious outburst.
Anyway, upon completing the IV antibiotics in the hospital, I then embarked upon a course of 10 IV treatments of hydrogen peroxide alternating with ten treatments of 10,000 – 15,000 mg of IV vitamin C at my naturopathic doctor’s clinic. By doing this, I:
a) healed much of the damage done by the antibiotics (I also took high dose Natren probiotics during and after and drank only Absorb Plus whilst in the hospital – to protect myself from toxic hospital food!)
b) prevented secondary or opportunistic infections from occurring (very common following IV antibiotic use)
c) cleared up the remaining pneumonia and fluid in my lungs (I also used inhaled glutathione, Infrared heat on my lungs and acupuncture)
Another “must-take” supplement that I recommend – vitamin D (but must be cholecalciferol – D3) is also recommended by this article as an immune system regulator. I recommend 3,000-4,000 IU per day in the winter if you live in a low-sunlight area. See my blog post for lots more info on vitamin D supplementation.
Also, remember that people with IBD or IBS need to take their vitamin C in mineral ascorbate form to prevent it triggering diarrhea.
And now, here’s the article:
ANTIBIOTICS AND VITAMINS WORK TOGETHER
(OMNS Dec 3, 2007) The benefits of using vitamin C together with antibiotics are considerable. In a controlled trial with dairy cows with infected udders, high dose vitamin C has been shown to have synergistic effects when used with antibiotics.  The cows were divided into two groups. One group was treated with antibiotics alone, and the other group was treated with antibiotics and the human equivalent of 10,000 mg/day injections of vitamin C. The vitamin C group got well much sooner: in just over half the time.
In humans, an astoundingly high 120,000 mg/day (nearly 2,000 times the RDA) of vitamin C delivered intravenously has been demonstrated to accelerate healing of burned skin in a blinded clinical trial.  1,000 to 3,000 mg/day (100 times the RDA) of niacin is a standard treatment for controlling cholesterol.  Similar doses of niacin have been demonstrated to reduce inflammation  and to reduce injury to the brain after strokes. 
Extensive evidence shows that vitamin D serves as an important regulator of immune system responses.  Many of these regulatory pathways are optimized when vitamin D is present in the bloodstream at levels considerably higher than average values in the American population. Regu
