MAT52, What I suggest is that you consider treating the RA and immune condition with a whole foods plant diet. This will treat the source of the problem instead of the symptoms. You would eat relatively-whole vegetables and fruits, organic if you can afford it, eliminating processed foods such as refined oils, refined sugars, flour, and preservatives. I would also suggest adding exercise and a stress-management technique such as meditation. You might look to John Bergman on youtube for more info and read my other posts, where I list many other resources for healing yourself naturally.
