The body is extenuated by going into warm water(23), and especially if it be salt, the bath with an empty stomach, a scorching sun, and all heat, care, watching, either too short or too long sleep; lying upon the ground in the summer time, and upon a hard couch in the winter; running, much walking, and all violent exercise, vomiting, purging, acid and austere things, and a single meal in the day, also a custom of drinking wine, that’s not very cold, upon an empty stomach. Since I have classed vomiting and purging amongst the methods for extenuating, I must say something in particular about them. I observe, that vomiting is rejected by Asclepiades in that book, which he composed upon the preservation of health; nor do I blame him, if he was offended with the custom of those, who by such daily evacuation endeavour to procure a voracious appetite. But he has gone something farther. He has also in the same book forbid purging. And indeed this is hurtful, if it be procured by too strong medicines. It can be no universal maxim however, that these should be laid aside entirely; because it is possible, that the nature of constitutions and particular junctures may make them necessary, provided they be used with moderation, and not without necessity; and even he himself has granted, that if any thing be corrupted, it ought to be expelled. So that this method is not to be altogether condemned, but there may be many occasions for it, and it requires a more particular and nice observation. [Sidenote: _Of vomits._]
