The Short Version
Chitosan's use in wound healing and drug delivery is well-documented across peer-reviewed literature, with FDA-cleared wound dressings and a multi-billion-dollar market supporting the claim's core assertion. Multiple high-authority reviews explicitly link chitosan's antimicrobial and biocompatible properties to these applications. However, the claim slightly overstates the picture by omitting known limitations — low solubility at neutral pH and poor mechanical properties — that constrain some clinical applications and blur the line between extensive research activity and universal clinical deployment.
