Transdermal Administration of Volatile Oil from <i>Citrus aurantium</i>‐<i>Rhizoma Atractylodis Macrocephalae</i> Alleviates Constipation in Rats by Altering Host Metabolome and Intestinal Microbiota Composition

Abstract

These findings suggest that ZBVO can alleviate STC symptoms by promoting intestinal peristalsis, increasing fecal water content, regulating gastrointestinal hormone level, reducing the inflammatory response, and regulating brain and intestinal peptides after transdermal administration. And structural changes in the intestinal microbiota are closely related to host metabolism and intestinal microbiota destroyed in STC modeling could be significantly improved by the ZBVO, which provides a reference for the development of aromatic drug macrohealth products.
