The famous Hong Thai herbal nasal inhaler from Thailand — widely sold in Vietnam and endorsed by BlackPink’s Lisa — has been found contaminated with bacteria and fungi, according to a warning from Thailand’s Food and Drug Administration (FDA).
Contamination Discovered in Lab Tests
In a public notice issued on October 28, the Thai FDA advised consumers to exercise caution when purchasing Hong Thai nasal inhalers after routine inspections revealed that certain batches failed to meet microbiological safety standards.
Samples collected from the Hong Thai Panich Herbal Products manufacturing facility tested positive for excessive levels of aerobic bacteria, yeast, and mold, and even traces of Clostridium spp., a bacterial genus that can be harmful to humans.
The tested batch was produced on December 9, 2024, and set to expire on December 8, 2027, Thai PBS reported.
Potential Health Risks and Legal Penalties
According to brandinside.asia, high bacterial counts suggest poor hygiene or improper storage during production, which can increase the risk of skin irritation, respiratory problems, or infections, especially for people with weakened immune systems.
Under Thai law, producing substandard herbal products can lead to up to two years in prison and a fine of 200,000 baht (US$5,400). Selling such products carries a six-month jail term or a fine of 50,000 baht (US$1,350).
Widely Popular in Vietnam
The Hong Thai inhaler is among Thailand’s most recognizable herbal products and has gained international fame after being mentioned several times by Lisa, a member of the K-pop group BlackPink, who said it helps her relax.
In Vietnam, the product enjoys strong sales on major e-commerce platforms, with prices ranging between VND 45,000–55,000 (US$1.70–2.20) and some listings showing over 100,000 purchases.
Many Vietnamese travelers also buy Hong Thai inhalers as gifts during trips to Thailand.
