A study in mice suggests it could help reduce sneezing linked to hay fever, researchers at Hiroshima University said.<\/p>\n\n\n\n<p>Matcha, a powdered tea made from specially grown leaves, is already associated with health benefits, including improved heart and brain function. The new findings, published in <em>npj Science of Food<\/em>, point to a possible role in easing allergic rhinitis, commonly known as hay fever.<\/p>\n\n\n\n<p>Professor Osamu Kaminuma and his team gave mice engineered to show hay fever symptoms matcha tea several times a week for more than five weeks. The animals also received an extra dose before exposure to allergens. The researchers found the mice sneezed less than expected.<\/p>\n\n\n\n<p>The effect did not appear to involve typical immune pathways such as immunoglobulin E (IgE), mast cells or T cells, which normally drive allergic reactions. Instead, matcha suppressed activity in the brainstem linked to the sneezing reflex.<\/p>\n\n\n\n<p>Analysis showed reduced expression of the c-Fos gene in the ventral spinal trigeminal nucleus caudali, a brain region activated during sneezing. \u201cOral matcha reduced sneezing without clearly changing major immune markers. Instead, it strongly suppressed brainstem neuronal activation,\u201d Kaminuma said.<\/p>\n\n\n\n<p>The next step will be to test whether the same effect occurs in humans. \u201cThe goal is an evidence-backed, food-based option that complements standard care for allergic rhinitis symptoms,\u201d Kaminuma added.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>TOKYO &#8211; Japan\u2019s matcha green tea may do more than provide a caffeine boost.
