I have recently become interested in oil of oregano for its touted anti-parasitic and possible healing properties. The only negative is that there are no double blind, placebo-controlled human studies that have been performed on its uses. However, there is still some research out there that may help guide us in the right direction.
I figured that since it is just oregano and olive oil (as the carrier oil), I would try it out 
(Disclaimer: Speak with your doctor before supplementing).
I haven’t done any testing on myself to see if I have any parasitic infections, H. pylori, or other bacterial infections. But, I have a sneaking suspicion that one of these three that is triggering my Hashimoto’s. I have done everything to heal so far except eliminate possible bacteria/parasite/fungi and I haven’t 100% eliminated dairy yet either. I figured it would be a more affordable method to try the oil of oregano, vitamin C, and a few other natural remedies before doing expensive testing.
- There is a decent study that came out in 2000 about 14 patients (with parasitic infections) that were healed with 600 mg after 6 weeks of use.
- There is preliminary research that came out in 2002 that showed oregano oil to kill fungal toxins, but it was not done in the human body.
- Then, in 2003, research compared 5 strong essential oils, and determine oregano oil to be the most effective bactericidal oil. It killed E. coli within 1 minute! Again, this was not done in humans, so more research is needed.
More Reseach Needed
Overall, more research is needed, but results are promising. The question is: what happens when we ingest the oregano oil? Does it stay intact and ready to kill bacteria, or does our stomach acid destroy it? Not sure. But, it would be more likely to kill H. pylori than other bacteria since it lives in the stomach. Any oregano oil or probiotics will survive better when taken with a higher fat food.
So, I am experimenting on myself–which I never recommend. But, of course, I am willing to do on myself.
The interesting thing is that if you read what hundreds of other people have to say about their experiments using oregano oil, they have great things to say about it. Unfortunately, you can not trust everything you read out there.
So was your conclusion the oregano oil was NOT good for thyroid?
I do not believe that it is NOT good for the thyroid, but I was questioning if it provides enough benefit to recommend it. I think it just depends on the person’s medical history to see if they may benefit (what their gut health and stomach health is like).
What’s the longest I can oregano and then how long do I need to be off of it before starting it again?
I’ve been taking oregano oil .on and off for my Underative Thyroid for about 2 years now ….and I have very severe pain….and it works brilliantly …I certainly recommend it
