Thanks to Nell Heard and Wendall Dean for this contribution. Wendall is a wood-carver and scroller. His carving buddies always keep a packet of black pepper on hand for times when they cut themselves on sharp tools.
Nell, her sister, and brother-in-law Wendall were traveling through Yellowstone in an RV. One evening a mug fell out of a cupboard and gashed Wendall's head. The cut was long but not deep, and Wendall asked Nell to put pepper on it. The bleeding stopped almost instantly, and the cut healed with barely a scar.
You may want to keep some black pepper handy in the kitchen and take a packet of pepper on your next camping trip. Not only does the bleeding stop quickly, the wound heals cleanly with little scarring.
