Just been reading the info on the Canadian PBC website and came across some advice one of their newsletters (Vol 1 2014). It reinforces the article Peridot posted a year ago. A small paragraph in an article titled 'Fibrosis in PBC' by Dr Angela Cheung says in answer to the question 'Is there anything else I can do to help my liver?'
'Believe it or not, drinking two to three cups of caffeinated coffee a day has been
shown to help decrease or stabilize liver fibrosis. Milk thistle, on the other hand, has not been shown to be helpful.'
I realise I'm probably finding this out after everyone else has known about it for ages but if there's anyone else who's only recently started digging for PBC information, it might interest them. The slightly annoying thing is that it took me years to wean myself off coffee and now .... maybe I'll try it & see how it affects my insomnia ....
