Patients with tumor chemotherapy can follow the doctor’s instructions to take Chinese medicine to regulate. Chemotherapy is a commonly used treatment for various types of malignant tumors. However, patients undergoing chemotherapy for tumors often suffer from a series of uncomfortable symptoms such as itchy skin, hair loss, numbness of hands and feet, loss of appetite, diarrhea, nausea and vomiting, and so on. From the perspective of traditional Chinese medicine, it is because the tumor depletes the body’s positive qi, resulting in imbalance of yin and yang in the body and dysfunction of internal organs. Traditional Chinese medicine can be prescribed according to the symptoms of each patient and his/her constitution to regulate the balance of yin and yang and the function of internal organs, which is helpful for alleviating the uncomfortable symptoms and improving the quality of patients’ survival after chemotherapy. Patients with tumors should regulate the treatment according to the treatment plan formulated by doctors. If taking traditional Chinese medicine, it is recommended that the preparation and use of traditional Chinese medicine should be carried out under the guidance of professional physicians, and should not be used by oneself to prevent adverse consequences.
