The current situation of TCM external treatment method Nowadays, TCM external treatment method is increasingly combined with modern technology, such as laser, far infrared, electromagnetic, ultrasonic nebulization and penetration, ion introduction therapy machine, etc.; constantly absorbing the achievements of modern medicine, reforming external treatment dosage form, such as drawing on hard ointment, film, chemical hot ironing agent, tolbu agent, new skin penetration promoter, etc., to promote the full absorption of drugs, which is also the modern research of TCM external treatment method This is also an important issue in modern research on TCM external treatment. The transdermal drug delivery system and transdermal treatment system originated from the West have collided with the topical preparations of Chinese medicine which have a history of more than 2,000 years, however, the research on transdermal drug delivery system of Chinese medicine is still in the primary stage. Research on single herbs with clear efficacy for topical application and dosage form reform of traditional herbal topical preparations will inject new vitality and vigor into transdermal drug delivery research. The development of matrices, excipients, and transdermal absorption enhancers from traditional Chinese medicine will also bring new ideas to transdermal drug delivery. Some Western medical experts do not recognize external treatment as a science, but they cannot deny the efficacy and the need for its existence. It is worth mentioning that the external treatment theories and formulas of Chinese medicine have become “foreign Chinese medicine” in the international arena, and “foreign Chinese medicine” has taken on a new look to occupy the international market, and even returned to the Chinese market. In the United States, TCM has infiltrated into universities, large companies, and large enterprises, such as the establishment of the School of Chinese Medicine at Miami University, the establishment of a Chinese medicine pharmacy at the University of California at Berkeley, and the investment in screening Chinese herbal medicine at Cornell University; more actively, internationally renowned pharmaceutical companies, such as Glaxo, Pfizer, Schweppes, Johnson & Johnson, and Roche, have invested considerable funds and manpower in the development of new herbal products. Unfortunately, in recent years, we have seen a downward trend in the investment and output of TCM external therapies. The severe form requires us, the technical backbone of TCM, to spare no effort in further tapping and passing on the essence of TCM.
