The decoction of Houttuynia cordata leaves has a significant inhibitory effect on Bacillus anthracis and Corynebacterium diphtheriae in test tubes, and also has a certain antibacterial effect on Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Salmonella typhi, and Shigella dysenteriae. Water and ethanol extracts of Houttuynia cordata from Nepal can counteract histamine on isolated guinea pig ileum, acetylcholine and carbachol on isolated frog rectus abdominis muscle. Using dog blood pressure as an indicator, water extracts of Houttuynia cordata from Nepal can counteract the effects of histamine, cholinomimetic drugs, and bradykinin on blood pressure, while ethanol extracts can only counteract the effects of histamine and cholinomimetic drugs on blood pressure, indicating that both have anti-histamine and anti-cholinergic effects. In addition, water extracts can weaken the contractile force of isolated rabbit hearts, slow down heart rate, and reduce coronary blood flow. Related discussions.
