Abstract:Mice were employed to study sedative and anticonvulsion effects of Rhizoma Typhon processed by different methods. The results showed that processed and raw Rhizoma Typhon had marked sedative effect and delayed convulsion time, caused by cardiazole and strychnine. Processed and raw Rhizoma Typhon had similar action. With the new processing method, similar sedative and anticonvulsion effects were obtained compared with the old processing mothod.
