Evidence Summary
Aloe vera is a versatile botanical used topically and orally, with significant research focused on wound healing, skin health, and radiation-induced skin toxicity. While evidence strongly supports its use for burns and radiation-induced skin reactions, some studies suggest potential delays in certain types of dermal wound healing.
Evidence by Condition
A meta-analysis supports the use of Aloe vera for the prevention and treatment of infusion phlebitis.
Systematic reviews support its efficacy for burn wound healing and skin graft donor sites, though one study noted a potential delay in certain dermal wound healing.
Multiple RCTs and systematic reviews indicate its effectiveness as a prophylactic agent for radiation-induced skin reactions.
RCTs demonstrate that Aloe sterol supplementation can improve skin moisture, collagen scores, and elasticity.
Evidence is limited to a single clinical trial investigating its remineralizing effects on deep carious lesions.
Effective Doses
Low-dose Aloe sterol supplementation has been studied for skin moisture and collagen benefits.
Key Findings
- Meta-analysis supports Aloe vera for the prevention and treatment of infusion phlebitis (PMID: 24895299).
- Systematic reviews support the efficacy of Aloe vera for burn wound healing (PMID: 17499928, PMID: 34550291).
- Aloe sterol supplementation improves skin moisture, collagen score, and objective/subjective symptoms (PMID: 32515040).
- Aloe vera gel is an effective prophylactic agent for radiation-induced skin toxicity (PMID: 8892458).
Limitations
Research is inconsistent regarding wound healing, as some studies suggest Aloe vera dermal wound gel may be associated with delayed healing (PMID: 2047051).
