主题：到底湿不湿，中医大师们又要打起来了 -- 胡一刀

The gut microbiota is hypothesized to have a critical role in metabolic diseases, including type 2 diabetes (T2D). A traditional Chinese herbal formula, Gegen Qinlian Decoction (GQD), can alleviate T2D.

In conclusion, our study suggests that structural alterations of gut microbiota, induced by Chinese herbal formula GQD, are associated with the anti-diabetic effects of GQD. In particular, this treatment enriched the number of beneficial bacteria, such as Faecalibacterium spp. in the gut. Although it is still unclear whether changes of gut microbiota by GQD directly contribute to the improvement of glucose homeostasis, our clinical study provides circumstantial evidence that gut microbiota might be involved.
