These Brown Recluse bites can sometimes look like third degree burns. Skin sluffs off. Oderiferous. And can leave one crippled to some degree.
Potato is well known for its drawing properties. The poultice formula I have heard of for recluse bites has Plantain (not the kind that makes banana type fruit) used for its drawing properties and it has enzymes that neutralize the venom. Earlier I said activated charcoal was part of it but I looked up the formula and it is steamed bituminous coal powder. That soaks up the exudate from the wound and neutralizes the bacteria. It also has Comfrey to stimulate cell proliferation, Echinacea to stimulate immune response and Lobelia which I can’t think offhand the purpose of.
