There are two reasons why chemotherapy drugs cannot kill all tumor cells at one time: First, chemotherapy drugs only work on tumor cells in the proliferation phase, but not on tumor cells in the dormant phase. Some tumor cells are growing, dividing and proliferating, while some are dormant, not eating, drinking or moving. When we kill certain tumor cells, the dormant tumor cells will enter the proliferation phase to replenish the tumor cells we have eliminated, which is why we designed multiple chemotherapy treatments. Secondly, chemotherapy drug kills tumor cells in logarithmic steps, that is, it only destroys a certain percentage of tumor cells each time, just like taking a glass of water with sugar and only allowing half of it to be poured out each time, do you think you can completely pour out the sugar? However, when the number of tumor cells is reduced below a certain level, they can be removed by our body’s immune system. This is why we use Chinese medicine to restore the immune function as soon as possible while chemotherapy. In the view of TCM, chemotherapy drugs are also a kind of poison. Chemotherapy is actually attacking poison with poison. While destroying tumor cells, chemotherapy drugs also damage the human body, firstly, the spleen and stomach are damaged, followed by the weakness of qi and blood. In recent years, many physicians have found that the use of Chinese herbal medicine in conjunction with chemotherapy is helpful to prevent the side effects of chemotherapy, improve the efficacy and enhance the body’s resistance to disease. The stomach is the sea of water and grain, and its nature likes to moisten but hates dryness, and its qi is descending to be smooth. In the treatment of chemotherapy drug-induced gastrointestinal reactions, TCM can play a certain role in reducing or controlling them. It is worth noting that although antiemetic western drugs have a strong antiemetic effect, they all have different degrees of side effects, especially constipation, which affects the quality of survival of patients. Chinese medicine can reduce the toxic side effects of antiemetic drugs on the one hand, and adjust the function of the spleen and stomach on the other hand, so that patients can increase their appetite and improve their quality of life.
