Aloe is great! Topically applied, the gel from the cut stem of the plant dries to form a protective layer on the skin's surface, preventing any dirt or bacteria from entering. Aloe contains a concentrated mix of enzymes, anti-inflammatory fatty acids, and compounds that boost the immune system and speed healing.

I find fresh aloe to be an amazing cure-all for burns and cuts. I recently discovered its fast healing power for a deep scratch I had on my hands from cutting roses in the garden. After applying antiseptic, I dabbed the gel from a fresh piece of my aloe plant and wow! it healed remarkably fast. The scratch turned a deep crimson color in the process.
