Enhanced antibacterial performance of chitosan nanoparticles loaded with gongying powder extract: A novel approach for bovine mastitis therapy

Gongying powder (GP) is a traditional herb used for treating bovine mastitis, but its therapeutic effectiveness is limited by adverse gastrointestinal effects and poor solubility. This study aimed to prepare hydroxypropyltrimethyl ammonium chloride chitosan (HACC) nanoparticles loaded with GP extract (GP/HACC-NPs)
