Pseudoaspidin is a natural compound derived from ferns, primarily studied for its broad antimicrobial properties, including activity against drug-resistant bacterial strains, Gram-positive bacteria, fungi, and potentially viruses. It has demonstrated efficacy in inhibiting bacterial growth, interfering with biofilm formation to enhance conventional antimicrobial treatments, and exhibiting antifungal effects. Additionally, research indicates anti-inflammatory properties, suggesting applications in treating inflammatory skin conditions, wound healing, and as a lead compound in pharmaceuticals, topical antiseptics, cosmetics, and health products aimed at reducing microbial infections.
