Designed for the Swedish Military, adopted by mountaineers and adventurers, Hudsalve is hearty, no-frills skin protection for lips, face, hands, elbows, and feet. A staple of many European armies, and necessity being the mother of invention, its uses have now grown to near mythical status. It has been used to grease weapons, and condition boots. Swedish tank commanders use it to combat mosquitoes. Some say it is edible, that is a line we have not crossed... but in a pinch, when no one's looking, it just might be suitable to grease your cast iron.
