>>798253If you have nothing else with you, try to see if you can find some plantain leaves while /out/. They're basically cosmopolitan at this point, and seem to grow anywhere where there's been a significant human presence.
The leaves themselves can be used as a decent salve for sunburns, bugbites, & cuts. You can chew on them and use the cud as a compress, which has saved my ass from infections dozens of times. While modern medicine is obviously preferable, plantains have always been a good last-ditch alternative.
