Chinese man has been charged with illegally producing and selling herbal medicine for more than a decade, including in his home province of Liaoning.

The man, surnamed Wang, has been living in the northern province of Inner Mongolia for more 20 years and has been accused of selling more than 30,000 capsules containing a synthetic compound that is also found in some herbal remedies.

His wife is also charged with helping him to make the pills.

Authorities have said they believe the pills were made by Wang’s wife, Li, and that they had not been tested for contaminants.

Li’s husband has been a suspect in several other drug cases and is currently in prison awaiting trial.
