In 1963, Blitz etal. first suggested that aloe may expedite wound healing by serving as a protective barrier due to its occlusive properties (Blitz etal., 1963). The occlusive cover-like qualities of the gel were later attributed to mucilage, which acts as a storage container inside the leaf. It also acts like a sealant or 'bandage' when a plant leaf is injured. It has been shown that dry wounds prevent the migration of cells and disrupt the effects of wound-healing growth factors (Thomas etal., 1998). Aloe gel, acting as a cover, has been shown to keep the wound moist, allowing excellent migration of epidermal and fibroblast cells (Shelton, 1991). In addition, the occlusive cover-like properties of mucilage allow it to serve as an organic bandage or dressing.
