Can bloodletting help someone with hepatic encephalopathy?

No. (?): "Bloodletting" refers to the ancient and long-discredited practice of bleeding someone to remove "evil humors" (another long-outdated concept). "Therapeutic phlebotomy" is used to treat diseases that cause overproduction of red blood cells or their constituents eg hemochromatosis, polycythemia vera, porphyria cutanea tarda. It is NOT indicated for hepatic encephalopathy.
