Since it is an anti-inflammatory and, from the study, seems to work on the same population as Prednisone. Perhaps it is a substitute for Pred. One would think that there is some sort of problem with it. Else, it would have become popular over the past 8 years since. Maybe it is more expensive to produce than Pred?
