Formulation of traditional Chinese medicine and its application on intestinal flora of constipated ratsOriginal paper
Karen Pendergrass is a microbiome researcher specializing in microbiome-targeted interventions (MBTIs). She systematically analyzes scientific literature to identify microbial patterns, develop hypotheses, and validate interventions. As the founder of the Microbiome Signatures Database, she bridges microbiome research with clinical practice. In 2012, based on her own investigative research, she became the first documented case of FMT for Celiac Disease, four years before the first published case study.

This study examined a self-extracted traditional Chinese medicine formulation developed to treat constipation. The researchers used 16S rRNA sequencing and qRT-PCR to characterize how this treatment altered the intestinal flora of constipated rats. The goal was to explore the mechanism and role of the Chinese medicine in relieving constipation through its effects on gut microbiota.
Who was studied?
The subjects were rats with experimentally induced constipation, treated with a certain dose of the traditional Chinese medicine extract. The abstract does not specify the exact number of animals, strain, sex, or age used in the experiment. This was an animal model study rather than a human cohort.
What were the most important findings?
Before treatment, constipated rats showed a significantly elevated relative abundance of Firmicutes, accounting for 86.7% of the flora. After treatment with the Chinese medicine, the gut microbiota changed significantly, with Lactobacillus abundance rising to 23.1% and its symbiotic relationships with other intestinal flora becoming enhanced. The total copies of intestinal bacteria in the constipated rats decreased following treatment.
What are the greatest implications of this study?
The findings provide a theoretical basis for understanding how this traditional Chinese medicine formulation acts on the gut microbiome to relieve constipation. The shift toward increased Lactobacillus and reduced overall bacterial load suggests a microbiota-mediated mechanism of action for the treatment. This supports further investigation into traditional Chinese medicine as a microbiome-targeted approach to constipation management.
