Chang Hsien-che, a professor at China Medical College, says that before there was a prohibition on tiger bones, DNA analysis would have revealed that less than five percent of what was being marketed as tiger bones in the cities was the real McCoy, and virtually none of it in the countryside was.
中國醫藥學院教授張賢哲表示，尚未禁用虎骨以前，若以 DNA 來化驗，都市的中藥房裡，真正的虎骨，恐怕五％都不到，鄉下則幾乎沒有。
