Granny - I'm not a physician, so take this FWIW..
Milk Thistle is the herb you're wondering about. It is reported to have "theraputic" and protective effects on the liver.
Dandelion is also reported to be excellent, as is Artichoke.
Of course, it's impossible to know if either of these would have any net positive effect on a particular medical condition, but I figured I'd pass along the info as I have a family member into "herbology" (or whatever in the heck it's called) and I just happen to know a lot of this stuff as a result.
Take care..
Thank you, those were the ones I was looking for.
