The effect of calcium gluconate with natural extracts on skin toxicity of hydrofluoric acid

Backgrounds Hydrofluoric acid (HF) is a highly corrosive acid. The conventional treatment for HF burn is topical application of calcium gluconate (CG). Our study aimed to assess the synergistic effects of natural extracts (Centella asiatica, Portulaca oleracea, and blueberry extracts) in combination with CG in healing HF induced burn wound.
