In terms of potentially beneficial bacteria, the abundance of Roseburia, Phascolarctobacterium, and Parabacteroides showed an increasing trend in the MPH group. Although the changes in abundance of these genera did not reach statistical significance (P > 0.05) in this study, their upward trend is consistent with the enhanced trend of the "butyrate metabolism pathway" observed in functional predictions (see 4.2.4). This suggests that even minor adjustments in microbial structure may have cumulative effects at the metabolic function level. Parabacteroides has direct anti-inflammatory and immune-regulatory capabilities and can inhibit key pro-inflammatory factors. Phascolarctobacterium produces acetate and propionate, which are involved in host energy metabolism regulation. The increasing trends of these genera suggest that Bu Xu Ping Chuan膏 (a traditional Chinese medicine) may improve the gut microenvironment by promoting the proliferation of beneficial bacteria.
