Recent research from Japan suggests that matcha green tea may help reduce sneezing associated with seasonal allergies, offering a potential natural complement to conventional treatments.
According to findings shared by researchers at Hiroshima University, regular consumption of matcha was linked to fewer sneezing episodes in laboratory models designed to mimic human allergic rhinitis. The study, led by Professor Osamu Kaminomura from the Institute of Radiation Biology and Medicine, involved administering matcha tea to test subjects two to three times per week for over five weeks, with an additional dose given 30 minutes before exposure to allergens.
Researchers observed a significant decrease in sneezing frequency, noting that the effect did not stem from immune system suppression—like many allergy medications—but rather from direct influence on the nervous system, particularly the brainstem, which controls the sneeze reflex.
The study highlighted that active compounds in matcha, including catechins and amino acids, may contribute to this effect through their anti-inflammatory properties. Importantly, the benefits were seen with consistent dosing over time, including the pre-exposure booster dose, which appeared to support a measurable reduction in symptom severity.
While the results are promising, scientists cautioned that matcha is not a cure for allergies and should not replace prescribed treatments. They emphasized the need for further clinical trials in humans to confirm both effectiveness and safety before any widespread recommendations can be made.
For individuals managing seasonal discomfort, these findings add to growing interest in dietary approaches that may support respiratory wellness during high-pollen seasons. As with any complementary approach, consulting a healthcare provider is advised, especially for those with existing conditions or on medication.
