section 31


And know ye, for all that, that it is good to let much blood often, in these sicknesses caused by plethora, in the fever caused by red blood, called synocha, and others of that ilk. It is good at times to let a vein often without drawing much blood from it, so as to maintain health;701 for Avicenna says it is better to increase the number of times rather than the quantity of blood; and at times it is good to let much seldom; as in the case of sicknesses accompanied by violent pain, such as quinsy and its like; it is good not to let much blood, neither to let it often, but in dropsy only a little and seldom.
