Aloe for External Ulcerations: Scientific Evidence Overview

Aloe vera has a longstanding history of use for wound healing, including the treatment of external ulcerations such as pressure sores, diabetic ulcers, and other chronic wounds. The gel extracted from Aloe vera leaves is rich in compounds like polysaccharides (notably acemannan), glycoproteins, vitamins, and amino acids, which are thought to contribute to its potential wound healing effects.

Scientific studies have explored Aloe vera's efficacy in promoting healing of external ulcerations. Several randomized controlled trials and systematic reviews suggest that topical Aloe vera gel may accelerate wound contraction, enhance re-epithelialization, and reduce inflammation. For example, a 2012 Cochrane review concluded that Aloe vera might improve healing rates for first- and second-degree burns, and some studies indicate potential benefits for chronic wounds or ulcers. Proposed mechanisms include anti-inflammatory, antimicrobial, and collagen-stimulating effects.

However, the overall quality of clinical evidence is moderate, with some studies showing positive effects and others finding no significant benefit compared to standard treatments. The variability in Aloe preparations, wound types, and study designs limits the strength of recommendations. Still, Aloe vera is widely used as an adjunct in wound care, and adverse effects are rare when applied topically.

In summary, there is scientific support for the use of Aloe vera in the management of external ulcerations, though the evidence is not uniformly strong. Aloe vera may be considered as a complementary option, especially for minor ulcerations, but more rigorous studies are needed.
