Wasabi and sinus clearing
Many people believe the wasabi clears their sinuses, but new research suggests that the spicy green paste may do the opposite. U.S. researchers found that eating wasabi appeared to increase congestion in a small group of healthy volunteers, despite the fact that participants said they thought that the spice had cleared their nasal passages. "Actually, wasabi is a congestant," says study author Dr. David S. Cameron. "It makes the space of your nasal passages smaller, but it makes you feel more open." Dr. David Cameron explains that wasabi probably clogs up sinuses by increasing blood flow to the lining of the nose. That extra blood takes up space, he said, which constricts the nasal passageway.
