I was taking Lufenuron (as a chitin inhibitor to destroy fungus) at the same time so there is a small chance that maybe that could have done it, but I'm about 80-90% sure that it was the Rutin that fixed me up due to the timing, and also the tummy pains that coincided with using Rutin and the end of the daily reflux symptoms.
Note that I don't need to keep taking Rutin (or Lufenuron) regularly as the pathogen living in my stomach, and causing reflux, is now gone. In other words it was a proper cure. I expect my reflux to eventually return, but I will now know how to get rid of it next time :-)

***** Rutin (or possibly Lufenuron). Rutin must not be taken when pregnant.
**** Licorice root tea with meals. Worked quite nicely.
*** ACV. Apple Cider Vinegar, 1 x tbsp 2x daily with juice.
??? Spinach seems to help

*** Animal fats, including butter and dairy (except yoghurt)
