Research on Antibacterial Activity in Vitro of the Houttuynia cordata Thunb Injection

Antibacterial activity in vitro of the Houttuynia cordata Thunb injection was studied in 2004~2005.Vapor distillation was used to produce Houttuynia cordata Thunb,a Chinese traditional medicine in injection.Antibacterial activity in vitro of the Houttuynia cordata Thunb injection was researched by viable count method and ampicillin sodium assistant method using staphylococcus.Result showed that Houttuynia cordata Thunb injection had certain antibacterial activity in vitro,which was evidently stronger than normal saline.It was concluded that the viable count method and ampicillin sodium assistant method were feasible and credible to measure antibacterial activity in vitro of Chinese traditional medicine.
