Lysozyme (LYSO), as an alkalescent protein micromolecule in living organisms, exhibits important pharmacological actions such as antibiosis, anti-inflammatory, antivirus and enhancing immunity. LYSO can combine with many exogenous and endogenous substances and carry many drugs. This essay summarizes interaction between different kinds of active components of natural medicines and lysozymes, which is significant to comprehensively understand pharmacological mechanism of natural drugs and their transfer and metabolic process in organisms, optimize molecule structures of drugs and increase bioavailability and biological effects of natural drugs.
