chewing oregano leaves

It all started when I noticed that I had eaten pizza several times with very little heartburn.  Somehow I made a connection with oregano and decided one night when I was ready to pop something for reflux to try about 1/2 tsp of oregano leaves and chewed them slowly and swallowed.  It was not an especially pleasant experience - kinda burns - but it was as effective as Pepcid, etc. - with no kickback or unpleasant feeling the next day.  It made my stomach actually feel good - a rare experience when you've got GERD. 
 
Like everything else I've taken, it seemed to lose its effectiveness after awhile, but I still keep a bottle by my bed and use it occasionally - always with results.  Anyone have any experience with this or care to try and get back to me?
 
 
I haven't but it is always interesting to hear the experiences of others. If we don't do it, who will? Thanks for posting your experience with oregano!
