How long is the patent period of Japanese traditional Chinese medicine?

First of all, after thousands of years of clinical practice, the classic prescriptions of traditional Chinese medicine have undoubtedly proved their inherent rationality. But what about China? But it is considered unscientific and needs to be tested by the standards of western medicine. As we all know, the clinical practice of a new drug is not something that ordinary enterprises can do, which not only has a long cycle, but also has a high cost, which seriously restricts the play of the value of traditional Chinese medicine prescriptions and makes the production and research of classical prescriptions seriously lag behind.

Japan, on the other hand, opened the production of classical Chinese medicine a long time ago. The Japanese summarized the clinical experience of China for thousands of years, and made some clinical verification by scientific means, so as to select some classic prescriptions for mass production. In this way, China's classic prescription shines brilliantly in Japan, earning a lot of money for Japanese pharmaceutical companies. For example, China's ancient prescription "Liushen Pill" was developed after Japanese transformation. Once popular all over the world, it was known as a "life-saving medicine" with annual sales exceeding $6,543.8 billion. Japanese traditional Chinese medicine "Lu Zheng Pill" has also been sold back to China. Among the countries applying for patents of traditional Chinese medicine in China, Japan, South Korea, the United States and Germany are the most enthusiastic.
