A man is being persecuted in China for questioning traditional Chinese medicine:

Mr. Zhang, a professor at Central South University in Hunan province who has been studying medical history for more than 30 years, is urging the government to stop promoting traditional medicine. He has launched an online petition to seek its removal from the constitution and the official medical system. And he wants China’s traditional-medicine practitioners to get mainstream medical training.

“From the viewpoint of science, Chinese traditional medicine has neither an empirical nor a rational foundation,” he wrote in an article that ignited a furor when it found its way onto China’s Internet. “It is a threat to biodiversity. And it often uses poisons and waste as remedies. So we have enough reasons to bid farewell to it.”
