As I drove him home, a guy threw his large and very full knapsack on the floor of my car, atop a just-bought bottle of rather expensive, pure horticultural vinegar. This organic formula was or is to take the place of the highly toxic "Roundup" product. I wasn't aware that the weight and impact of his bag had broken off the screw-top of the bottle till I was driving home, and the edges of my lips were burning. Half the vinegar had leaked into the floor mat, which of course I removed at home, washed and aired. However, after 3 days, the edge of my lips are still painful and too dry to absorb anything. Lip balms, even the "natural" ones, seem to burn it more, as would butter on a burn, the old wives' tale cure that doesn't work either. I've thought of aloe for it heals burns on regular skin but burns mucous membranes further, so I'm searching for another option. If you've used aloe on your lips and it's worked, I'd like to be proven wrong. Right now, I don't want to risk it.
I doubt that there are many out there who've experienced this particular involuntary poisoning by an organic product, but there may be a few among you with the healing instinct!
Strongest vinegar legal for sale retail in Colorado is 5% canning vinegar - mostly because the stronger agricultural vinegar is so caustic. I guess you have to be licensed/certified to buy and use it here.
