Use aloe vera gel or sap to treat burns on skin. It works to heal all kinds of burns, including hot water burns, sunburn and chemical burns. Many people drink aloe vera 
to treat asthma and even to boost their immune systems.
There are compounds in aloe vera such as mannans, lectins and anthroquinones that help to reduce inflammation. You can purchase pre-mixed aloe juice or you can make your own by mixing two ounces of aloe vera sap (or gel) with four ounces of water for a homemade tincture.
The naturally occurring proteins in aloe combined with the plant compounds mentioned above are what give aloe vera its’ uniques healing potential. If taken internally, drink in moderation. For topical application, there is no limit as to how much to rub onto your skin. There are no negative side effects.
