CM and CG were used to establish a spleen deficiency constipation mouse model. After the model was finished, CG was infused with 0.15 g\/mL Massa Medicata Fermentata water infusion at a dose of 4 g\/(kg\u00b7day), twice a day, at 0.4 mL. An equal amount of distilled water was infused in CC and CM for 7 days. The body weight and fecal water content of the mice were monitored during the modeling. Following the intervention, 16S rRNA amplicon sequencing was used to analyze changes in the microflora in the intestinal contents, and serum substance P (SP), vasoactive intestinal peptide (VIP), and calcitonin gene-related peptide (CGRP) levels were determined via ELISA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The modeling had no significant effect on the weight of the mice, the water content of the mice\u2019s feces was greatly reduced, and the feces were dry and hard. Constipation caused by spleen deficiency can lead to a decrease in serum SP and an increase in VIP and CGRP. After treatment with Massa Medicata Fermentata, SP, VIP, and CGRP all changed. Intestinal microbiota diversity of mice with spleen deficiency constipation, and the dominant microbiota and characteristic microbiota changed, indicating that the intestinal microbiota was unbalanced. After the intervention of Massa Medicata Fermentata, the intestinal microbiota diversity of spleen deficiency constipation mice increased; the dominant microbiota became <jats:italic>Candidatus<\/jats:italic> Arthromitus, <jats:italic>Lactobacillus<\/jats:italic>, unclassified Bacilli, <jats:italic>Bacillus<\/jats:italic>, <jats:italic>Ligilactobacillus<\/jats:italic>, <jats:italic>Muribaculaceae<\/jats:italic>, <jats:italic>Bacteroides<\/jats:italic>, and <jats:italic>Enterorhabdus<\/jats:italic>; and the characteristic microbiota became <jats:italic>Candidatus<\/jats:italic> Arthromitus.
