Histopathological examination of skin treated with propolis-EXTR and propolis-NLCs after 14 days. The left panel shows representative H&E images for the control wounds treated with Carbopol gel (control), propolis-EXTR, and propolis-NLCs loaded on Carbopol gel. The images reveal scab formation (black round tip arrow) and epithelium formation (white round tip arrow) under the scab. Scale bar = 400 µm. The right panel shows representative images for Masson Trichrome staining for the control wounds treated with Carbopol gel (control), propolis-EXTR, and propolis-NLCs loaded on Carbopol gel. Scale bar = 50 µm
