Can we use l-carnitine or vitamin e or selenium or milk thistle as a treatment for idiopathic chronic liver hepatitis of unknown origin?

Hepatologist: Instead of trying to manage your condition yourself, go and see a liver specialist and follow their directions.

Yes, also...: All of those are perfectly safe & reasonable to try, but i would make sure the e is natural with mixed tocopherols, as the evidence suggests that synthetic vit e is toxic! selenium often helps with viral infections, as does vit. C. Consider seeing a homeopath & acupuncturist, since conventional medicine has little to offer in this situation. See a holistic doc: http://www.Abihm.Org/search-doctors.
