This study has been bought to my attention and I thought I'd share it with everyone.
The test sample were all women and given the incidence of RA in women, the study organisers were going to get a pool of subjects more easily.
"The phytonutrient and dietary supplement quercetin has been shown to lower disease activity and reduce clinical symptoms in women with rheumatoid arthritis."
Might be worth a go perhaps...
It's a double blind randomised trial with a link off to PubMed to the original study.
