Xlear Nasal Wash

Xlear Nasal Wash is the brand name of a saline-based nasal spray containing xylitol. Xlear claims to be effective in reducing bacteria in the nose and eustachian tubes, thus decreasing the risk of sinus infections, while improving such conditions as allergic rhinitis and asthma.^{[citation needed]} Studies have shown that the presence of xylitol prevents the growth of bacteria in the eustachian tubes which connect the nose and ear.^{[1] [2]} Xylitol also interferes with the ability of bacteria to adhere to body tissues^[3].
