A method for extraction of Chinese herbal medicines using a small molecule micro-shear technology, including: pretreating, jet milling, grinding, pulverizing, cell-wall breaking, and extraction of Chinese herbal medicines, so that the raw material can be fully utilized. Herbs are cut into small molecule substances, which is easy to be absorbed by the means of a superfine grinding technology and a cell-wall breaking technology. By means of a supercritical carbon dioxide extraction technology, active ingredients in Chinese herbal medicines can be efficiently and singly extracted, and organic solvent residues in the raw herbs can be removed.
