When processing raw and sun-dried ginseng, only the reed and body of the American ginseng and the middle and upper parts of the branch root which has uniform thickness should be retained, and all others are pinched off. The truncation part of the large root should be cut properly, and it should not be left too long. The thin fibrous roots in the middle and upper part and the thick part of the main body should be removed, and the other parts should be retained.
Wash away the dirt and scar residues on the roots. Before washing, soak or wet the roots of fresh ginseng with water, and then rinse it with a washing machine or high-pressure water pump, or manually wash and rinse with water.
