Acemannan is the principal bioactive polysaccharide from Aloe vera gel, responsible for much of its wound-healing activity in burns. Preclinical studies show acemannan activates macrophages, accelerates wound contraction, and promotes re-epithelialization in burn wound models. It is specifically identified as a key constituent mediating aloe vera's documented burn-healing effects in clinical research.

A clinical study in 64 patients (31 experimental, 33 control) at Ataturk University Hospital found that an ointment of A. tinctoria, beeswax, and olive oil applied to second-degree burns accelerated epithelialization, reduced pain during dressing changes, and shortened hospital stays. The active naphthoquinones alkannin and shikonin are recognized as key wound-healing constituents. A 2002 rabbit model study also confirmed burn wound healing benefit.

Allantoin has documented clinical and preclinical use in burn wound management, particularly in combination formulations. Silver-zinc-allantoinate cream was studied in a clinical series of 264 patients with chronic cutaneous ulcers including burn-related wounds, achieving healing in 339 of 400 lesions. Tissue engineering research has also incorporated allantoin into wound scaffolds specifically designed for severe burns.

Multiple systematic reviews and controlled clinical trials support topical aloe vera gel for partial-thickness burns, showing statistically significantly faster healing times and higher rates of complete healing compared to silver sulfadiazine and other comparators. A meta-analysis (Burns, 2022) found the mean time to wound healing significantly favored aloe vera (RR: -1.34, 95% CI: -1.8 to 0.9, p<0.001). Level 1 evidence also indicates pain relief in partial-thickness burn wounds.

Topical bee pollen ointment has been tested in pig burn wound models, demonstrating reduced healing time, improved tissue histopathology, and antimicrobial efficacy. A Chinese clinical trial specifically evaluated bee pollen-based preparations for burn wound treatment in humans.

Bromelain is the active constituent of the EMA-approved debridement agent NexoBrid® for deep burns. Multiple RCTs and systematic reviews demonstrate bromelain-based enzymatic debridement reduces time to complete debridement, lowers surgical excision rates, and improves spontaneous healing and cosmetic outcomes compared to standard care. A 2025 meta-analysis found faster debridement (MD -3.92; p<0.00001) and higher spontaneous healing rates with bromelain.

Calendula officinalis has a long traditional history as a burn and skin inflammation remedy in European herbal medicine.
