The drug (Yinzhihuang) was being used to treat neonatal jaundice (in the U.S., the frontline treatment for this problem is phototherapy using fluorescent lighting, a very safe procedure).

Seeing that yinzhihuang (typically a mixture of herbs including Artemisia capillaris) is sold over the Internet for liver problems, potential buyers researching it might want to consider the risks involved in buying a product made in China or which has ingredients of unknown origin.

Remember you'd better research all medical procedures and medicines from traditional western as well as herbal medication you take. The life you save may be your own. I would'nt listen to any medical persons advice on this forum. They are nothing more than spammers trying to push a failed health system down your throats.
Chantix is of course not being taken off the market by Pfizer. And of course the FDA ALLOWED the chinese drug Heparen in the USA.

I would like to be able to buy pure and effective supplements; unfortunately our laws and their enforcement are severely lacking, so we have to depend on warnings once contaminated herbal drugs and supplements reach the market.

It's still a good idea to be extremely wary of any Chinese-manufactured drug or supplement, given the lack of ethics and oversight involved in their sale and "regulation".
