Objective: To investigate the effects of processing and compatibility of ginger for the treatment of cold asthma rats at the metabolomics level by gas chromatography-mass spectrometry (GC-MS). Methods: The rats of cold asthma were established by ovalbumin (OVA) + ice water bath. The rats divided randomly into the control group, model group, Linggan Wuwei (fresh/dry/stir- frying) Jiangxin Decoction group and the positive drug Guilong Kechuanning group. The pathological changes of lung tissue were observed by HE staining; The inflammatory cell count in BALF and the content of IgE, IL-4 and IFN-γ in serum were determined. GC-MS was used to conduct the non-targeted metabolomics study to search the serum and urine related differential metabolites in rats with cold asthma, and MetaboAnalyst was used to construct related metabolic pathways. Results: The results showed that Linggan Wuwei (fresh/dry/stir-frying) Jiangxin Decoction improved the pathological changes of rat lung tissue, significantly reduced the BALF inflammatory cell count in BALF and IgE and IL-4 levels in serum, and increased IFN-γ levels. Compared with the control group, 37 differential metabolites (15 in serum and 22 in urine) were screened in cold asthma rats. And seven metabolic pathways involving energy metabolism, oxidative stress may be associated with cold asthma by Metaboanalysis pathway analysis. The overall metabolic profile of the cold asthma rats with the intervention of Linggan Wuwei (fresh/dry/stir-frying) Jiangxin Decoction tended to normal levels. The effect of Linggan Wuwei (dry) Jiangxin Decoction on cold asthma was better than Linggan Wuwei (fresh/stir-frying) Jiangxin Decoction. Conclusion: It is more reasonable to process ginger into dried ginger in Linggan Wuwei Jiangxin Decoction against cold asthma. Ginger processing-compatibility may play a therapeutic role in cold asthma rats by regulating energy metabolism and oxidative stress.
