Remedy for Torpid Liver
One of the best and simplest remedies for torpid liver or biliousness is a glass of hot water with the juice of half a lemon squeezed into it, but no sugar, night and morning. A person to whom this was recommended tried it, and found himself better almost immediately. His daily headaches, which medicine had failed to cure, left him, his appetite improved, and he gained several pounds within a few weeks. This is so simple a remedy that any person thus afflicted will do well to give it a trial, as it cannot possibly do any harm.
