A method for removing aflatoxins from Chinese herbal medicines comprises the steps of grinding a predetermined Chinese herbal medicine and submerging it into an amount of alcohol solvent twice as much as the dry weight of the medicine and using water to flush away the alcohol solvent from the medicine after a being submerged for a predetermined period of time.
