Methods Coptidis Rhizoma was extracted by water, and then selected some indicators to evaluate the toxic effects of Coptidis Rhizoma by using C. elegans as model organism. The effects of different concentrations of water extracts of Coptidis Rhizoma on lethality, maximum lifespan and median lethal time, individual development, spawning number and locomotion behavior were measured to evaluate the toxic effects on C. elegans. Results Compared with the control group, the lethality of C. elegans was significantly increased by water extract
