[Research progress on the effects of proanthochanidins in reshaping microbiota and suppressing inflammation]

Proanthocyanidins (PCs) are a class of polyphenols that are composed of flavanate monomers and their polymers, which have antibacterial and anti-inflammatory properties with very few side effects. This article reviews the mechanism by which PCs differentially regulate microbiota, reshape microflora diversity and play a role in suppressing inflammation, providing a reference for the basic research of PCs in improving female vaginal health, and is expected to provide a new idea and breakthrough for the combined use of PCs with other antibacterial drugs in the treatment of vaginitis.
