Why ayurvedic stopped working in hpylori

I was h pylori positive ! I had taken avipattikar churna, yasthimadhu churna,kamdudha Ras,giloy satva,sankha bhasma ! It worked pretty great and after I got better doc advised me to just take plain avipattikar churna ! Now once I stopped taking avipattikar churna mix h pylori again kicked in and to my surprise it didn't even work even after taking the same medicine as before ! It worked but not as good as before ! So after taking it for like 3 months my doctor switched my medicine to avipattikar churna,praval pishti , sutshekhar ras, kamdudha Ras! And the same story repeated !! It worked really well but after I stopped taking medicine h pylori again started troubling me! And now the Medicine again does not work as before and now I have erosive antral gastritics!! Any solutions ???
