Antibacterial effect

The whole herb decoction has a significant inhibitory effect on human catarrhalis, Staphylococcus aureus, Shigella flexneri, Geranium, Group B Streptococcus, Pneumococcus, etc. in test tube. The tannin contained in it has a certain influence on its antibacterial effect. It has a significant inhibitory effect on Asian influenza A virus Jingke 68-1 strain and parainfluenza virus type I Sendai strain. The MIC of geraniol contained in this product against Trichophyton mentagrophytes and Microsporum audouinii is 0.39ml/ml.

Antiviral effect

The decoction of the whole herb has a significant inhibitory effect on Asian influenza A virus Jingke 68-1 strain and parainfluenza virus type I Sendai strain (tested by chicken embryo, hemagglutination test); its leaves and stems have a stronger effect on the former, while the root has a weaker effect; the tannic acid it contains has little effect on its antiviral effect. Through the screening test of chicken embryo inhibition of influenza virus, geranium has a certain inhibitory effect.

Antidiarrheal effect

The water-soluble extract of Japanese geranium has a certain antidiarrheal effect on rabbits. When rabbits take its decoction or dry extract on an empty stomach, it can inhibit the activity of the duodenum and small intestine and promote the reverse peristalsis of the cecum, thus producing an antidiarrheal effect; but if the dosage is too large, it can promote the peristalsis of the large intestine and produce a laxative effect.
