When I lived in Az my Mexican friends turned me on to the medicinal qualities of Aloe Vera. I found it to be one of the best healing agents available and it's free. For many yrs I had Aloe plants in my yard and used it often on skin wounds, abrasions and burns. It worked better than most prescription salves. I only used fresh cuttings so can't speak to the commercial salves that contain Aloe. I had a little Jack Russel Terrier that was plagued with severe allergies during spring pollen season. Aloe Vera helped him when everything the vet prescribed did nothing to help. I was even talked into drinking an Aloe "shake" for some internal problem that I don't recall if it worked or not. That was pretty vile tasting so don't want to do that again. Was my leg being pulled about drinking it or has anybody else tried it? I now live where the winters are below freezing will Aloe plants survive cold winters, I doubt it? I really miss having it available.
