Lucas Papaw ointment. Made from the fermented fruit of the papaw plant. Can be used for everything: boils, burns, chaffing, cuts, cracked skin, gravel rash, insect bites, nappy rash the list just goes on.
Its that safe and natural, you can eat it without any problems not that i would but a freind of mine has for some aliment and he swears by the stuff.
It 's really cheap, can be purchased in any supermarket or health food shop, smells fine and has good staying power. Something similiar in the States could exist as its made in Australia. For Australian readers give it a go.
