spp. Nevertheless, poor solubility and limited bioavailability still hinder their clinical translation. Strategies such as nano delivery systems and β-cyclodextrin complexes are discussed to improve bioavailability. Although andrographolide itself has not received regulatory approval as a stand-alone drug, several andrographolide-containing preparations have been clinically used in certain countries. Overall, this review brings together evidence on antiviral, antibacterial, antifungal, and antiparasitic activities, linking them with structure-activity trends and pharmacokinetic insights, thereby providing a consolidated foundation for future development and clinical translation.
