That’s the difference between the number of years that Traditional Chinese Medicine has been in practice versus the number of years that conventional Western medicine has been in practice.
I liked this quote I pulled from an article:
‘”To Westerners, scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses,” says Chuang Shih-ming, a Chinese medicine doctor based in Taipei City.
“Chinese medicine also takes the same approach,” he argues. “The only difference lies in the fact that Western medicine uses about 200 years of such ‘scientific’ methods of observation and testing of hypotheses to prove its effectiveness, while the Chinese version uses several thousands of years.”‘
