Consumer protection police on Tuesday raided premises where medicines and beauty products were being illegally produced in Nakhon Pathom province.
They seized a large quantity of unregistered goods worth an estimated 500,000 baht.
Pol Col Chanannat Santhawalpaet, commander of the Consumer Protection Police Division (CPPD), said the raid followed information from the Food and Drugs Administration (FDA), which had monitored sales of these products by the website www.auraslimbeauty.com.
An investigation led to a court warrant to search the premises in Nakhon Pathom. He did not disclose the location.
He said goods seized from the premises included about 200,000 capsules of unnamed and unregistered medicines, 1.2 million blank capsules, filler substances, weight-reduction supplements and substances affecting the nervous system, valued around 500,000 baht in total.
A woman who said she was the owner was present. Pakthita Ploykaew said she alone produced the seized products.She said she was once an assistant to a pharmacist, from whom she learned about various kinds of medicines, Pol Col Chanannat said.
The woman said she began her business by ordering the ingredients, then mixing them and filling blank capsules. She sold the goods on the website.
Pol Col Neti Wongkularb, who led the CPPD raid, said all the seized goods would be sent to the Medical Science Department for examination.
FDA deputy secretary-general Supatra Boonserm said illegal sales of unregistered medicines, particularly for weight reduction, were of great concern.
Ms Supatra said the weight reduction products usually contained sibutramine, an appetite suppressant which could cause nerve disorders and even death.
Pol Col Chananan said production and sale of unregistered medicines violated many laws, including the Medicine Act of 1967, Medical Equipment Act of 2008 and Food Act of 1979.
