Salviae miltiorrhizae(SM) Radix extract increased $[^3H]-thymidine$ incorporation into rat hepatocytes at the concentration ranging from $5{ imes}10^{-5};to;5{ imes}10^{-1}mg/ml$. It decreased the activities of s-GOT and s-GPT in cirrhotic rats induced by $CCl_4$, TAA and D-GalN, respectively and reduced the sleeping time induced by hexobarbital in $CCl_4$,TAA and D-GalN intoxicated mice, respectively. SM extract shortened the half-life of sulfobromophthalein in $CCl_4$ intoxicated rats.
