it will be stopped in this way. If a thrombus be formed in the opening,
it will inflame and suppurate. Venesection is to be practiced when
the person has dined more or less freely and drunk, and when somewhat
heated, and rather in hot weather than in cold.
When in cupping, the blood continues to flow after the cupping-instrument
has been removed, and if the flow of blood, or serum be copious, the
instrument is to be applied again before the part is healed up, so
as to abstract what is left behind. Otherwise coagula of blood will
be retained in the incisions and inflammatory ulcers will arise from
them. In all such cases the parts are to be bathed with vinegar, after
which they are not to be wetted; neither must the person lie upon
the scarifications, but they are to be anointed with some of the medicines
for bloody wounds. When the cupping instrument is to be applied below
the knee, or at the knee, it should be done, if possible, while the
man stands erect.
