Aloe vera gel is one of nature's great healers. It can be used to treat sunburn, moisturize skin and soothe irritation. To make your own, all you need is a healthy aloe plant. If you have a lot of gel and you want it to keep for a month or two, mix in 500mg powdered Vitamin C or 400 IU vitamin E for every 1/4 cup of gel you have. Place the ingredients together in a blender and blend well. The gel will look foamy at first.
