• one or more medicine-containers consisting of a number of storage units for storing different sorts of Chinese medicines,
• a fetching means for fetching a certain quantity of medicine bags from the storage unit,
• a transmitting and guiding means for putting medicine bags from the fetching means onto a conveyer belt,
• a warning means for identifying and warning if certain medicine bags run down or are misplaced,
• a control device for controlling said fetching, transmitting and guiding, and warning means according to a prescription for blended Chinese herbal medicines,
• wherein said medicine fetching means comprises a first valve, a second valve, and a control system, said control system controlling said first and second valves such that said first valve will open and deliver the certain quantity of medicine bags and then close, whereby in the end, the second valve will open and the drugs are fetched.
