SINGAPORE : The Health Sciences Authority (HSA) has issued a warning against a product called Power 1 Walnut.

The public is advised not to consume this illegal product.

It is believed to contain two potent ingredients - glibenclamide and sildenafil. The ingredients are prescription-only medicines which should only be taken under strict medical supervision.

The product's label stated the manufacturer as Guangzhou Xinkauili Company.

Based on HSA's preliminary investigations, the product is likely to have been illegally brought into Singapore.

It claims to contain only natural herbal ingredients and is marketed for sexual enhancement in both men and women.

The HSA said it had received serious adverse drug reaction reports of two male patients who had consumed Power 1 Walnut. They had developed very low blood sugar levels.

This condition, if untreated in time, could lead to unconsciousness, seizures and sometimes death. - CNA/ms
