I started using Oil of oregano back in 1992, and that's when I discovered that when taking the pure oil, it needs to be mixed with another oil - a healthy one of course like Olive oil. It really helps cut the burning time down!
If you are considering taking oil of oregano, there's nothing like it being encapsulated!!! So look for the pills, much easier to take and no burning!
I've used Oil of oregano for bronchitis that wasn't responding to abx and my doc at the time told me it was quickly turning to pneumonia and that I had "3 days to show improvement or else you will be admitted to the hospital"
What he never found out was that I wouldn't have gone into the hospital, because I started taking my trusty oil of oregano and using another herb that
opens up the bronchial air ways. Three days later when I went back to the office, he was just happy to see that the abx were working! LOL! Oh well.
