Aloe is derived from the gel of the cactus-like Aloe plant. This plant is native to Africa and commonly referred to as aloe vera. It survives by retaining more than 95-percent water in its thick leaves. This is why the Aloe Vera plant can survive in very dry, hot climates where most other plants perish.
For centuries, Aloe gel has been used to heal skin lesions, skin irritation and dryness. Its success has also made it a common additive to cough syrups. Aloe works most effectively when applied directly from the plant. Therefore, it's a common first aid staple found in houses around the world. Skin care products containing natural aloe vera, are thought to be the most trustworthy defense against skin dryness and sunburn.
