Colorectal cancer is one of the common malignant tumors of the digestive tract, with high morbidity and mortality.The main treatment methods are comprehensive therapies such as surgery, radiotherapy, chemotherapy, and targeted therapy. However, current surgery is not ideal. Although targeted drugs , radiotherapy and chemotherapy drugs can inhibit tumor growth, they also have strong side effects, seriously affecting the daily life of patients. Common symptoms of colorectal cancer include abdominal pain, fatigue, anorexia, mucus, pus and bloody stools, abdominal distension and pain, loose stools, soreness of waist and knees, thirst, tenesmus, etc. The more common syndrome types in traditional Chinese medicine include: blood stasis and internal obstruction type, spleen and kidney yang deficiency type, damp and heat accumulation type, liver and kidney yin deficiency type, and qi and blood deficiency type. The physical signs of each syndrome type are obviously different. At present, Western medicine is the main treatment for colorectal cancer, but if combined with traditional Chinese medicine to support healthy qi, regulate the spleen and stomach, and dispel evil and detoxification, a significant improvement can be achieved.
