Conclusions
Camellia sinensis cream demonstrated significant protective and reparative effects on burn-induced skin damage, suggesting its potential as a natural, effective, and safe alternative for burn management.
Methods
Thirty-two male Sprague-Dawley rats were randomized into four groups: control, Burn only, Burn + Camellia sinensis extract, and Burn + Camellia sinensis cream. Skin biopsies were evaluated using histopathological, immunohistochemical, and biochemical methods. Malondialdehyde (MDA) and glutathione (GSH) levels were measured to assess oxidative stress, while histological damage and immunoreactivity for collagen I, collagen III, NF-kβ/p65, TNF-alfa, 8-OhDG, and caspase-3 were analyzed.
Objective
Burn injuries are among the most common causes of trauma globally, affecting millions annually. Current treatments often rely on topical agents, but alternatives to synthetic formulations are increasingly sought due to safety and efficacy concerns. This study aimed to evaluate the therapeutic effects of a cream containing Camellia sinensis (white tea) extract on third-degree burn-induced skin lesions in a rat model.
Results
The Camellia sinensis cream significantly reduced MDA levels and increased GSH levels compared to the burn-only group (p < 0.001). Histological analysis revealed enhanced epidermal regeneration and reduced dermal damage. The immunohistochemical findings demonstrated reduced NF-kβ/p65, TNF-alfa, 8-OhDG, caspase-3, collagen I, and collagen III immunopositivity in the cream-treated group (p < 0.001). Conclusions: Camellia sinensis cream demonstrated significant protective and reparative effects on burn-induced skin damage, suggesting its potential as a natural, effective, and safe alternative for burn management.
