The traditional Chinese concept is that traditional Chinese medicine is a vague concept. The quality of medicinal materials varies depending on the conditions under which the herbs are planted. But in fact, certain parameters of traditional Chinese medicine can be considered controllable. Taking German gingko yellow as an example, although the raw materials Ginkgo is also collected from all over China, and there are differences in the raw materials themselves, but after extraction through German technology, the product quality is eventually uniform. This also means that the post-production processing process has a certain buffering effect on the differences in the raw materials themselves. What does this text say? ['Chinese medicine can be controlled by technology to a certain extent due to the difference in the quality of raw materials.', 'Chinese herbal medicines are not as good as foreign ones.', 'There is a big difference in the quality of Chinese medicine.', 'The quality of the medicinal materials after the German technical extraction is better.']
