Global Research Validating Nasaleze’s Safety and Effectiveness
Valor Health Co., Ltd., the exclusive importer of Nasaleze in Thailand,
is proud to represent a healthcare innovation from the United Kingdom
that has been clinically proven and scientifically validated through over 40 international trials
conducted by leading professors, physicians, and research institutions worldwide.
🔬 Mechanism of Action and Key Ingredient
The active component in Nasaleze is Hydroxypropyl Methylcellulose (HPMC) —
a plant-derived cellulose powder that forms a protective gel barrier inside the nasal cavity,
trapping and blocking allergens, PM2.5 dust, and airborne viruses before they can reach the nasal mucosa.
Dr. Roger Henderson, Senior GP and medical author from the UK, explains:
“Research has shown that methyl-cellulose powder — the key ingredient in Nasaleze —
acts as a significant barrier against cold viruses and inhaled allergens such as pollens.
The addition of powdered garlic extract in Nasaleze Travel and Nasaleze Cold & Flu Blocker
provides further protection against airborne infections, particularly for those who travel frequently.”
Over 30 clinical studies have demonstrated the efficacy and safety of HPMC
in reducing nasal allergy symptoms, confirming that Nasaleze is drug-free, non-steroidal, and safe for all users,
including children and pregnant women.

It has shown statistically significant improvements in nasal symptoms
and quality of life for allergy sufferers worldwide.
As summarized by Dr. Jean Emberlin, former Scientific Director at Allergy UK and
Professor at the University of Worcester, UK:
“I have conducted three double-blind placebo-controlled clinical trials with Nasaleze
and can confirm its efficacy in reducing allergic rhinitis symptoms with no known side effects.
Nasaleze acts as a physical barrier, stopping pollens and airborne allergens from reaching reactive cells in the nose.”
