Took milk thistle. stomach upset so stopped. same time had flu (not stomach flu) but lost appetite & nauseous esp after food. feels like when my gallbladder was inflamed. have i caused damage?

Probably not: But if the symptoms persists for more than a week or gets worse, you need to see a doctor since the problem may not be related to milk thistle at all.

Not sure it helps...: The medical literature is quite mixed as to the potential value of milk thistle in treating the liver. Lots of things of course cause elevated liver enzymes, ; milk thistle certainly may be of little use for many liver diseases. Regarding your present symptoms, they may have little to do with recent use of milk thistle ; should be independently evaluated (esp. If underlying liver/biliary disease).

NO, however...: Milk thistle has been the subject of many research studies. While the results are mixed re: benefits, the studies have found it is quite safe. However, it can cause nausea, but this should stop as soon as you stop taking it. It does not cause gallbladder inflammation but gallbladder problems are common whether you have taken milk thistle or not. See http://bit.Ly/16m9ire ; http://bit.Ly/1jlxytu.
