Researchers at the University of Wisconsin-Madison compared two stress reduction techniques and the effect on inflammation.
Apparently stress plays a major part in chronic inflammatory conditions like rheumatoid arthritis and asthma.

While both techniques reduced stress and inflammation, the mindfulness meditation were found to be more effective.
The size of the study and the specifics were not discussed in the article here:
