A peculiar Chinese issue

To the extent that traditional Chinese medicine ideas encourage the rapacious use of animal parts for no good reason at all, I wish it would go away.   But I didn't realise the Chinese government has a protective attitude towards it:

A Chinese doctor who was arrested after he criticized a best-selling traditional Chinese remedy has been released, after more than three months in detention. Tan Qindong had been held at the Liangcheng county detention centre since January, when police said a post Tan had made on social media damaged the reputation of the traditional medicine and the company that makes it.

On 17 April, a provincial court found the police evidence for the case insufficient. Tan, a former anaesthesiologist who has founded several biomedical companies, was released on bail on that day. Tan, who lives in Guangzhou in southern China, is now awaiting trial. Lawyers familiar with Chinese criminal law told Nature that police have a year to collect more evidence or the case will be dismissed. They say the trial is unlikely to go ahead.

The episode highlights the sensitivities over traditional Chinese medicines (TCMs) in China. Although most of these therapies have not been tested for efficacy in randomized clinical trials — and serious side effects have been reported in some¹ — TCM has support from the highest levels of government. Criticism of remedies is often blocked on the Internet in China. Some lawyers and physicians worry that Tan’s arrest will make people even more hesitant to criticize traditional therapies. 

 He was arrested under something like a defamation law (spreading false information) when he criticised a company's popular health liquor.  You can read about it at Nature.
