RESULTCalcium oxalate crystals isolated from above three rau rhizome typhonium rhizome showed strong irritation effects on rabbits' eyes. Under the condition of same content of calcium oxalate crystals, there were no difference in irritation effect between the suspensions of raw medicinal materials and pure calcium oxalate crystals.
