A widely used traditional Chinese medicine, Sanjin Watermelon Frost Insufflations, has been recalled from retail shelves in Singapore after it was found to contain berberine—an undeclared substance that may pose safety concerns.
According to an official announcement from the Health Sciences Authority (HSA), the recall affects batch number XJP24101 of the product, which carries an expiry date of 20 October 2027. The recall, classified as a Class 2 recall, is being carried out at the retail level, meaning the product must be removed from shops, pharmacies, clinics, hospitals, and wholesale suppliers across Singapore.
What Triggered the Recall?
The affected batch was flagged during routine testing under HSA’s product quality surveillance programme. Tests revealed the presence of berberine, a chemical compound found naturally in certain plants like barberry and goldenseal. Although berberine has known medicinal uses, it is not permitted in all formulations and may pose risks, particularly when consumed without proper medical supervision.
As a precaution, Kinhong Pte Ltd, the local distributor of Sanjin Watermelon Frost, has been instructed to cease all supply of the affected batch and initiate returns from all retail points.
What Is Sanjin Watermelon Frost?
This product is a Chinese Proprietary Medicine (CPM) commonly used for treating sore throats, mouth ulcers, and other minor oral infections. It is widely recognised for its cooling, anti-inflammatory properties and is often used in traditional remedies.
Consumers who may have already purchased this product are advised to check the batch number on the packaging and stop using it if it matches XJP24101. While no serious health risks have been reported so far, consumers should consult a healthcare professional if they have any concerns or experience unusual symptoms after using the product.
How Serious Is a Class 2 Recall?
In Singapore, a Class 2 recall is issued when a product defect is unlikely to result in serious health effects. This differs from a Class 1 recall, which is reserved for products that pose immediate dangers such as severe health complications or death.
While this recall does not automatically mean the product is harmful, it reflects Singapore’s high regulatory standards for public health and safety. HSA clarified that some recalls are purely precautionary to maintain consistent product quality in the market.
