Aloe vera is a medicinal plant that grows in hot climates such as California, New Mexico, and the Caribbean. It contains more than 75 active ingredients, including enzymes, amino acids, vitamins, and minerals, some of which could make it useful for treating diseases.
Some people use aloe vera gel as a home remedy to treat burns and other skin conditions and heal wounds. Aloe juice is also promoted as a natural remedy for diabetes, heartburn, and inflammatory bowel syndrome (IBS). There is some research suggesting that it works for these and other conditions, but more research and higher-quality studies are needed to confirm these benefits.
 
Aloe vera comes as a gel that you can apply to your skin and as a juice or gel that you can drink. The leaf also contains a yellow liquid called aloe latex.
This plant-based remedy contains chemicals that reduce swelling in the skin, relieve redness and scaling, soothe itchy skin, and promote the growth of new skin cells. These properties make aloe vera useful for treating skin conditions such as:
Acne
Cold sores (herpes)
Cuts and scrapes
Insect bites and stings
Minor burns and sunburn
Psoriasis
