This study tested licorice root extract mixed into a special wound-dressing film made with nanotubes and zinc oxide. The films showed better strength, moisture control, and antibacterial properties—and the licorice extract released slowly over time, staying active longer than it normally would.
Researchers created experimental wound-dressing films by combining sodium alginate, xanthan gum, and zinc oxide-filled nanotubes with licorice root extract. They tested the films' physical properties, antibacterial activity, and how the licorice extract released over time.
