(5) Inhibit the solidifying of blood platelet caused by adrenaline and ATP, prevent the symptom of thrombus and arteriosclerosis;
(6) Inhibit the activation of collagenase, strengthen collagen;
(7) Activation to anti-ulcer, inhibit the activation of Enz of carcinoma cell and restrict the breeding;
(8) Cure pathological changes omentum hemorrhagic disorders, and prevent cataract;
(9) Adjust the value of blood glucose for diabetics, reduce the injection quantity of insulin;
(10) Powerful effect to anti-oxidant and clearing free radical.
