Those, who have stated returns of this pain, before them ought both by a strict regimen to take care to prevent the redundancy of hurtful matter in the body, and to use frequent vomiting, and if there is reason to apprehend a present plethora, either clysters, or purging by milk. Which Erasistratus declared against, when the feet were gouty; lest the course of the humours downward should occasion a redundancy in the feet: though it is evident in every purgation, that not only the superior parts, but the inferior also are emptied. CHAP. XXV. OF THE TREATMENT OF PATIENTS RECOVERING. From whatever distemper a person is recovering, if he gathers strength slowly, he ought to awake at day-light, nevertheless to lie still in bed; about the third hour to rub his body gently with his hands anointed. Then to amuse himself by walking as long as he finds it agreeable, laying aside all attention to business; then to use gestation for a long time, much friction; to change often his situation, air, and food. When he has drunk wine for three or four days, for one or even two to interpose water. For by these methods he shall both escape those distempers, that bring on a consumption, and may quickly recover his strength. But when he is entirely recovered, it will be dangerous for him to change his course suddenly, and turn irregular. Therefore he ought by slow degrees to lay aside these restraints, and change to the way of life most agreeable to his humour(38). A. CORNELIUS CELSUS OF MEDICINE. _BOOK V._ PREFACE.
