Matcha Quiets Sneezes by Targeting the Brain, Mouse Study Finds

A Hiroshima University study in mice finds that regular matcha intake reduces sneezing caused by allergen exposure by dampening brainstem activity linked to the sneezing reflex, without significantly changing immune markers like IgE, mast cells, or T cells—hinting at a brain-mediated, diet-based approach to managing allergic rhinitis; human studies are planned to confirm applicability.
