The external treatment method of Chinese herbal medicine has local therapeutic and systemic regulating effects through local skin or meridian system absorption, penetration and stimulation, or direct action on the affected area of the body. A small amount of Chinese medicine can produce significant therapeutic effects, the mechanism of which, in addition to traditional Chinese medicine theory, may be due to the biological activity of the external treatment Chinese medicine and the external sensitivity and amplification effect of the meridian points themselves. On the one hand, the acupuncture points selected for external treatment are externally sensitive, which makes it easy for drug information to penetrate into the organism; on the other hand, since the meridian system is a multi-level, multi-functional and multi-morphic regulatory system, the biological activity of herbal medicines may produce obvious physiological effects by affecting the receptors; at the same time, the sensory transmission process of external treatment drugs through meridians may produce mutual excitation, synergistic effects and superposition between them, resulting in physiological amplification effects, and thus extremely small amounts of herbs can produce significant therapeutic effects. Among these methods, moxibustion therapy is the first and foremost, which has significant local and systemic effects on anti-cancer. The author has verified its view through the clinical efficacy of various external treatment methods. This therapy has the advantages of low dosage of drugs, low side effects, clear efficacy, and easy acceptance by patients.
