And it is cured by warm baths and drinking more fluid. So this is a case of driving out bad fluid by good fluid, not of a therapy that would cause coughing in healthy people. Similarly too much food can cause intestinal trouble for a weakened person, in those cases food is still the best cure. The doctor should judge in each case separately whether to treat diarrhea with fasting or with food. In all cases the physician must know the deeper cause of the disease.
Some people think that 'homoios' and 'autos' merely means 'fitting', 'of the same kind'.
So the first quote above merely says that cause and remedy belong to the same class. This man was treated with hellebore, in combination with lentil water and washing of his underbody. Then he recovered. So Hahnemann thinks that this unfortunate Athenian was cured by the hellebore rather than in spite of it. Part of the recommended treatment is letting the patient drink still more of the same water, to upset his intestines and cause 'evacuation from below'.
