Lots of "remedies" have been shown in the medical books over time. A few of them remain in use after testing. Review "The Barefoot Doctor" for lots of useful ideas or the Wilderness Medical Society practice handbook for those that have shown clinical usefulness. One that is used regularly by the medical profession (especially dentists) is a tea bag for reducing bleeding. Open wounds like those from oral surgery can be helped by a tea bag. I carry one in all my first aid kits, for a warm drink and to stop bleeding (or for ME when waiting for transport -- with the honey I carry also). Well vetted by clinical practice, it is one I highly recommend.

Respectfully,
