This study observed the pharmacological effects of Feilike Mixture(FLKM) in stopping cough, eliminating phlegm, and relieving asthma through animal experiments, and explored its mechanism using network pharmacology. The antitussive effect was detected by citric acid-induced guinea pig cough model, the expectorant effect by mouse phenol red excretion experiment and lipopolysaccharide-induced mucus hypersecretion rat model, and the antiasthmatic effect by histamine phosphate-induced guinea pig asthma model. The chemical components of FLKM were collected by TCMSP, TCMID, TCMIP, and BATMAN-TCM databases and literature search, and the potential active components were screened through ADMETlab 2.0. The targets of FLKM were obtained by STITCH, SwissTargetPrediction, and TCMSP, and the symptom targets of cough, phlegm, and asthma were acquired through SymMap database. After taking the intersection of FLKM targets and symptom targets, this study used the OECloud tool to perform Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analysis. RESULTS:: demonstrated that FLKM 0.43-1.74 g·kg~(-1) reduced the number of coughs in guinea pigs within 3 min(P<0.05, P<0.01), and FLKM 6-12 g·kg~(-1) increased the tracheal phenol red excretion in mice(P<0.01). Moreover, FLKM 2-8 g·kg~(-1) inhibited the number of goblet cells(P<0.05, P<0.01), and FLKM 7-11.2 g·kg~(-1) prolonged the incubation period of asthma(P<0.05). A total of 115 potential active components and 910 targets of FLKM were obtained through network pharmacological analysis. FLKM had 27, 12, and 7 targets for stopping cough, eliminating phlegm, and relieving asthma, respectively. The GO and KEGG enrichment analysis found that there were commonalities and characteristics, among which cytokine-cytokine receptor interaction and infectious disease-related signaling pathway were shared. FLKM has a good effect of stopping cough, eliminating phlegm, and relieving asthma through animal experiments and network pharmacology.
