About gall stones

I had gallbladder sludge, fatty infiltration of the liver (both dx
from an u/s) and elevated liver enzymes (the blood test that led to
the u/s being ordered.) After doing a few flushes, the ultrasound was
repeated and I still have the fatty liver but my gallbladder is clean.
My liver enzymes remain high.
I read that the herbal remedy milk thistle can help heal the liver,
and I’m wondering if anybody here has taken it. I bought a bottle of
milk thistle capsules. How often should I be taking it, at what
dosages, and how long should I continue? Should I skip the herb on a
day I do a flush?
If I do a liver/gb flush about once a month, when in my menstrual
cycle would work best? Any ladies have any input on this?
