How to preserve aloe vera?
How can aloe vera be processed and preserved for use as a skin cream? Something you could put in a tub, keep in the fridge, and slather on when needed.
I know that it should not be heated, because that destroys some of the active ingredients. I think some of the commercial brands use vitamin C: how would this be done at home?
I wonder if it could be pickled. I have some recipes for pickling vegetables using lacto-fermentation (whey, actually). This is a very old (pre-vinegar) system that is said to boost the nutritional content of the vegetables--although I wouldn't be eating it, just applying it to the skin.
Has anyone tried to do this at home?
