“…There were many other examples highlighting the microbial change during the treatment of obesity, diabetes and metabolic syndromes (Table 1). These examples include Daesiho-Tang (DSHT) that attenuated obesity and significantly increased the relative abundance of Bacteroidetes, B/F ratio, Akkermansia, Bifidobacterium, Lactobacillus, and decreased the level of Firmicutes (Hussain et al, 2016), Gegen Qinlian Decoction (GQD) alleviated Type 2 diabetes and significantly increased Faecalibacterium prausnitzii (Xu et al, 2015), while Qushi Huayu Decoction (QHD) reduced HFD-induced non-alcoholic fatty liver disease (NAFLD), and significantly increased the abundance of Parabacteroides and decreased the abundance of Odoribacter, Rikenella, Tyzzerella, Intestinibacter, Romboutsia and 2 members in Lachnospiraceae (Leng et al, 2020). Other examples related to gut microbiota changes included (Table 1): 20% Folium Mori amelioration of diabetes (Zhang et al, 2019a), Xiexin Tang-mediated improvement of type 2 diabetes (Wei et al, 2018), amelioration of human type 2 diabetes by metformin and a traditional Chinese herbal formula, AMC (Tong et al, 2018), Huang-Lian-Jie-Du decoction-mediated treatment of hyperglycemia and insulin resistance (Chen et al, 2018b), improvement of type 2 diabetes by treatment with Qijian (Gao et al, 2018), Banxia Xiexin decoction on diabetic gastroparesis rats (Xu et al, 2018), Houttuynia cordata facilitation of metformin on reducing insulin resistance (Wang et al, 2017b), berberine, the main bioactive alkaloid of Coptis chinensis, on glucolipid metabolism and insulin resistance in diabetic mice (Han et al, 2016;Liu et al, 2018a), and rhein's role in antidiabetic effects (Wang et al, 2018b).…”
