Traditional Chinese medicine fermentation refers to the biological transformation of active ingredients in whole medicinal materials, after cleaning or other processing, under specific environmental conditions, utilizing microbial life activities. Traditional Chinese medicine fermentation can lead to detoxification, increased efficacy, improved taste, and other advantages. Probiotics can balance intestinal flora, enhance immune function, and improve animal health.
