External treatment is an important part of the traditional treatment method of Chinese medicine. In the treatment of tumors, the ancients also developed rich external treatment methods in addition to internal medicine. For example, for the treatment of breast rocks, Sun Simiao used Chi Long Tang and Tian Ma to wash it, and put on the cream of Fei Wu and Fei Wu San. It is also suggested that “if the patient starts to suffer, apply Scutellaria baicalensis and Huang Lian Hu Fan San. In the Song Dynasty, the word “cancer” was first mentioned by Dongxuan Jushi in his book “Weiji Baoshu”, and “cancer” was listed as one of the five types of carbuncles and gangrene, and the external treatment of “cancer” was recorded by applying musk paste. In Ming Dynasty, Chen Shigong used moxibustion and toadstool cakes for the treatment of callus lip. <> said: “One is to pluck and the other is to cut. Where the disease is agglomerated, the plucking of the disease will come out from the disease, no deep internal trap; where the disease passes through, the cutting of the evil will be cut off from the danger of delusion and transmission.” The function of ointment is eloquently summarized. At present, plasters are widely used in the external treatment of tumors and have achieved certain curative effects. The clinical application of plaster should also be treated with evidence, for skin allergy, more local exudation or ulcers are cautiously used or prohibited. Zhang Jinyue said: “Where the treatment of accumulation, but four methods, said attack, said elimination, said dispersal, said tonic. The treatment of accumulation is to know the suitability of attacking and replenishing, when in which is slow and which is urgent to identify. Where the hard accumulation, must be outside the intestines and stomach, between the collection of the original, the original non-medicinal force can be sudden to, it is appropriate to use ferula cream, amber cream, or water safflower cream, three sage cream, such as to attack its outside; then use the long Sangjun needle method, to attack its inside”. This method of using both inside and outside, acupuncture, medicine and cream is in line with the special situation of tumor treatment. In clinical practice, according to the clinical characteristics of tumor, we have developed a cancer suppressing and analgesic ointment, which is used externally to relieve cancer pain and has achieved very good clinical effects. Clinical observation shows that: it has good analgesic effect on cancer pain, and its effective rate is 83.3%. At the same time, the experimental research shows that the cancer suppressing and analgesic cream formula has good tumor suppressing effect.
