Borax for Sinus Infections: Restore Smell and Taste Naturally

Using 1/2 teaspoon borax + 1/4 teaspoon sea salt in 8 oz filtered h2o, in neti pot for each nostril, twice daily, for chronic sinus issues (presumably mold triggered) which have plagued me for 5 years, and it's amazing after 1 month have recovered severely compromised olfactory function: I can smell w/80% efficiency, compared with say 10% previously. The borax really works well in neti pots!
