LAS41008 (DMF) effective in the treatment of psoriasis

[Turnedlight]

I've just been reading Caroline's thread explaining dmf, I found it very interesting, I remember studying the Krebs cycle as they called it at school. I was wondering, is the citric acid cycle pretty much what they are referring to when talking about your metabolism?
Also, there's a mention of purines, but I don't quite understand the context - would it be good to cut purine intake down at all?

I guess these questions are pretty much for Caroline if she knows the answers..
