Who knew? If emergency occurs... While the blood is gushing - hold pressure and crack open an egg. Peel that membrane off and put it on the wound (continue holding pressure) The membrane will harden and keep the wound closed until you can get to the ER for stitches. Repin just in case, you never know what will happen!
I made a poultice with activated charcoal and immediately applied it when my son was bitten by a brown recluse spider. I saved his arm from necrosis. He still needed antibiotics, but he will make a full recovery without any physical scarring!
