Aloe vera for treating acute and chronic wounds

Area of Science:

• Dermatology
• Wound Healing Research
• Natural Product Therapeutics

Background:

• Aloe vera, a succulent plant, is traditionally used in tropical climates.
• Animal studies suggest Aloe vera may accelerate wound healing.
• Its potential therapeutic effects on human wounds require rigorous investigation.

Purpose of the Study:

• To evaluate the efficacy of Aloe vera products (dressings, gels) in healing acute and chronic wounds.
• Assessing Aloe vera's impact on lacerations, surgical incisions, burns, and ulcers.
• Determining if Aloe vera accelerates or impedes the wound healing process.

Main Methods:

• Systematic review of randomized controlled trials (RCTs) evaluating Aloe vera for wound treatment.
• Searched multiple databases including Cochrane, MEDLINE, EMBASE, AMED, and CINAHL.
• Included RCTs assessing Aloe vera, its derivatives, or combined therapies, with wound healing as the primary endpoint.

Main Results:

• Seven trials (347 participants) were included; five focused on acute wounds (burns, hemorrhoidectomy, skin biopsies).
• Aloe vera showed no significant benefit for burns or skin biopsies; it reduced healing time for hemorrhoidectomy wounds.
• For chronic wounds, Aloe vera did not improve pressure ulcer healing and delayed surgical wound healing.
• High risk of bias in included trials necessitates cautious interpretation of results.

Conclusions:

• Lack of high-quality clinical evidence supports Aloe vera for wound treatment.
• Further rigorous research is essential to validate Aloe vera's role in wound care.
• Current findings suggest caution when using Aloe vera topical agents or dressings for wounds.
