This Littlepixie just popped in to say thank you for the invite to this thread.
I have a few suggestions:

For burns:

aloe-vera gel straight from the plant(that's the gooey almost clear stuff found inside its plump frond/leaves).
Here is a link that supports my above suggestion:

Please preppers, learn about the edible weeds that grow in many places.

The flowers from both with and red clover are edible, the red clover is better tasting IMHO.

Within the link that follows I hope you will find many wild edible/healing plant surprises:
