What are the advantages of medicinal herbs over acupuncture and what are the disadvantages?

In general, the Chinese idea is that you move body energy with acupuncture; not more. You remove obstacles, add more where there is too little and substract where there is too much. So far, so good: But what happens when someone no longer has enough energy, or simply has a fundamental deficiency?

Then acupuncture - in general - alone does not seem to be sufficient. Simply put: when the tank is empty, the car does not move: nothing happens. So the question arises where to get this fuel. The aim of giving medicinal herbs is to replenish used energy and restore reserves. renew so that the body can work with it. So much for the theoretical explanation.
