A herbal tea shop in Dongguan City, Guangdong Province, has been fined and its owner has been sentenced to seven months in prison for illegally adding chlorpheniramine maleate, ibuprofen, and chlorpheniramine to homemade herbal teas. The addition of western medicines to food is illegal and can pose food safety risks. The "Food Safety Law" prohibits the addition of drugs to food, but allows substances that are both food and Chinese herbal medicines. Consumers have the right to demand ten times the compensation from the producer and seller if substances not of the same origin are added to food. The case highlights the importance of food safety and the need for continued supervision and crackdown on the addition of western medicines to food.
