Adaptogenic flower buds exert cancer preventive effects by enhancing the SCFA-producers, strengthening the epithelial tight junction complex and immune responses.

Abstract Microbiome therapy has attracted a keen interest from both research and business sectors. Our lab has been applying this “second genome” platform to assess the functionality of herbal medicines with fulfilling results.
