TV dramas, especially palace fighting dramas, often see such a scene. The old or seriously ill emperor is designed by the concubine of the harem to use ginseng, codonopsis and other great tonic medicinal materials. After a while, the emperor noticed that he took too much medicine, why not only did the body not get better, but gradually got worse? Generally, the plot here would be the emperor will go die, and the audience knows that the play is over. At this time, the audience wondered, what is the situation, the medicine is not poisonous, why does the emperor dead? This is about a little knowledge in traditional Chinese medicine, the weakness of body cannot be tonified too fast.

The weakness of body cannot be tonified too fast means that the physical state of body is not good, resulting in the inability to eat foods or medicines that are nutritious or too effective. To put it in another way, for example, after an earthquake or some natural disaster, when the rescue team rescues the wounded from the rubble, the medical team usually does not give a large amount of water to the wounded who have been short of water for a long time. To help them drink slowly, because at this time, the human organs cannot work properly, and fast replenishment will increase the burden on the organs. 

Commonly used tonic herbs, such as ginseng, codonopsis, warm herbs such as atractylodes, etc. have strong medicinal effects. If the body is too weak, you can choose the herbs that are used for supplementation, such as American ginseng, magnolia officinalis, asparagus and so on. A story, the Empress Dowager Cixi was weak in the spleen and stomach, and the imperial doctor used American ginseng instead of ginseng to get good results, and also lead to the popular selling of American ginseng in the common people.
