Hi I had gone through your query. Patients of ankylosing spondylitis respond very well to the Ayurveda treatment but these treatments are not focussed to killing anything.... rather it works on their own principles like vatanuloman etc. The good thing for you is that you must get relief in your conditions by Ayurveda medications (telling you by my experience on innumerable patients ). If you elaborate your symptoms I may suggest some medications but direct interaction with a qualified Ayurveda physician would be more fruitful. Hope I have answered your query. If you have any further query I will be happy to help.
