The natural treatment for E coli urinary infection is based on oats. It is a very simple recipe and has no other harmful side effects.
Boil a handful of oats in 2 lliter/0.5 Gal until only one liter/0.25 Gal is left. Drink it in the morning, noon and evening, before meals for 30 days. The oat must boil until it pops.
This natural recipe has been passed down by a monk from Mount Athos and it can substitute antibiotic treatments for other kinds of infections.
