Chinese medicine is very dialectical, for example, external application depends on the therapeutic purpose of external application of Chinese medicine. For example, for phlebitis caused by various drugs, when the blood vessels become red, swollen, hot and painful during infusion, the best effect is achieved by using Juju San, basically the efficiency is over 90%. The efficacy is slightly less than 50%-60%, such as cancerous pleural fluid, cancerous ascites, pericardial effusion, cancerous pain, including deep vein thrombosis, including cysts in the body cavity, etc. The efficacy is slightly less. The most difficult and time-consuming treatment for solid masses is external application. Solid masses are also divided into superficial masses, such as lymph nodes on the body surface and metastatic tumors on the skin, which are more effective, but the efficacy of external application for deep solid masses in the body cavity is poor. However, if the patient has no other treatment options, external application is also necessary, but it takes a long time to fight. There is a clinical patient with small intestine mesenchymal tumor liver metastasis, external application of Chinese medicine for six months, the mass on the liver shrunk from 9.8cm to 5.5cm, indicating that external application of Chinese medicine for complete intracorporeal tumor is not necessarily ineffective, but just needs time.
