Small doses of ginger have no effect on the small intestine of guinea pigs, while high doses have an inhibitory effect. Both small doses of ginger and ginger have partial antagonistic effects on rat intestinal tension and tonic contractions caused by acetylcholine and barium chloride. Ginger decoction has varying degrees of inhibitory effect on experimental gastric ulcers in pyloric ligation, stress, and reserpine type rats by gavage, but its effect on indomethacin (indomethacin) type gastric ulcers is not significant. In vitro experiments showed that the minimum inhibitory concentration (MIC) of ginger decoction against Yersinia coli and Proteus morganii was 1/160 (with moderate antibacterial activity), the minimum bactericidal concentration (MBC) was 1/80 (with low bactericidal activity), and its inhibitory and bactericidal effects on Shigella flexneri were 1/40 and 1/10, respectively, indicating low efficacy. It did not exhibit inhibitory or bactericidal effects on enterotoxic Escherichia coli.
