Researchers created a wound-healing film that combines licorice root extract with zinc oxide nanoparticles. When licorice was added to the formula, it boosted antibacterial and antioxidant activity, improved skin cell survival by 20-40%, and released the licorice slowly over time rather than all at once—meaning the benefits lasted longer.
Scientists mixed sodium alginate and xanthan gum (natural film-forming ingredients) with tiny halloysite tubes loaded with zinc oxide and licorice extract, then tested how well the resulting films performed in lab conditions for wound healing.
