My wife 32 patient of ra since 9 years , uses methotraxate etc. suggest complete cure.

Not cure but helpful: Some RA patients are helped (not cured) with dietary changes. Trying eliminating all sugar, dairy (casein) and gluten. Not just most, but since this is immune-system related, all. You may also want to try a completely vegan diet. Be strict for 2 months and see if there is improvement. If so, then work with your doctor to see if tapering medications is possible. It's simple, but not easy.
