Daxie has a cooling blood to stop bleeding, detoxification swelling effect, after the charcoal to enhance the role of hemostasis. It can be seen that the efficacy changes before and after processing. In order to search for the essence of the changes, this experiment determined the contents of Cu, Fe, Mn, Zn, Ca, P, Si and other seven elements in the giant salamander. 1 The experimental material, Cirsium japonicum pc, is a dry plant of the Asteraceae plant. It was collected in Heilongjiang Provincial Academy of Forestry in September 1992. 2 Experimental methods Barley processing and determination methods: Samples were rinsed with deionized water, dried in an oven at 80°C (about 2 hours), and pulverized over 38 mesh.
