Dry cupping is performed by throwing a piece of paper dipped into
spirit of wine, and ignited, into a wineglass, and placing it over the
part, such as the neck, temples, &c. It thus draws the flesh into the
glass, and causes a determination of blood to the part, which is
useful in headache, and many other complaints. This is an excellent
method of extracting the poison from wounds made by adders, mad dogs,
fish, &c.
