All excesses are inimical to Nature. It is safer to proceed a little at a time, especially when changing from one regimen to another.
HippocratesAnd he will manage the cure best who has foreseen what is to happen from the present state of matters.
HippocratesThere are some arts which to those that possess them are painful, but to those that use them are helpful, a common good to laymen, but to those that practise them grievous. Of such arts there is one which the Greeks call medicine. For the medical man sees terrible sights, touches unpleasant things, and the misfortunes of others bring a harvest of sorrows that are peculiarly his; but the sick by means of the art rid themselves of the worst of evils, disease, suffering, pain and death.
