There are also reports that 0.6-0.9g/kg of Stemona decoction administered orally has no antitussive effect on cough induced by 1% iodine solution injected into the right pleural cavity of cats; 10ml/kg of Stemona alkaloid extract injected intraperitoneally has no antitussive effect on cough induced by sulfur dioxide in mice. 2ml/kg of 100% Stemona alkaloid extract administered orally to rabbits has no expectorant effect.

Effect on anti-pathogenic microorganisms: In vitro tests show that the decoction and alcohol extract of Stemona have different degrees of inhibitory effects on pneumococcus, beta-hemolytic streptococcus, meningococcus, Staphylococcus aureus, Staphylococcus albus, Shigella dysenteriae, Salmonella typhi, Salmonella paratyphi, Escherichia coli, Proteus, Diphtheria bacillus, pneumonia bacillus, plague bacillus, anthrax bacillus, Bacillus subtilis, Vibrio cholerae, and human tuberculosis bacillus. The water extract of Stemona ramosus has a certain inhibitory effect on certain pathogenic fungi in vitro. The decoction of Stemona ramosus can reduce the pathogenicity of Asian influenza A virus to mice, and also has a therapeutic effect on infected mice. The Newcastle virus test using chicken embryos showed that Stemona ramosus can extend the life of chicken embryos by 36 hours.

Insecticide: The water and ethanol extracts of Stemona ramosus and other varieties of Stemona ramosus can kill mosquito and fly larvae, head lice, clothing lice and bed bugs, etc. The alcohol extract is more effective than the water extract. A 50% distilled water suspension of Stemona ramosus ethanol extract can kill pubic lice in a few minutes, while the water extract is ineffective.
