I urge you to keep aloe around - if you can't have or don't want the plants, then buy some aloe gel to keep around. It's not as good as the real thing, but it's better than nothing.
I've also read that putting frozen french green beans on a burn helps a lot too! Just put the beans on the burn. Pour the juice of it on and wrap in a towel for 15 minutes. Repeat again for another 15 minutes.
