Specifically developed to rinse nasal and paranasal sinus cavities. Dos Medical nasal saline contains a combination of sodium chloride and sodium bicarbonate. It is also available with a hint of mint. Rinsing nasal and paranasal cavities with Dos Medical nasal saline benefits people that suffer from - common cold, - sinus inflammation (= rhinosinusitis) - allergy (hay fever and / or mites and / or animal dander) - after nasal surgery (to prevent crusts) - helps reduce snoring (snoring when it is caused because of swollen nasal mucosa) Dos Medical nasal saline is composed in collaboration with ENT specialists. Nasal saline with xylitol has been developed with ENT surgeons especially for patients with (chronic) rhinosinusitis. Nasal rinsing or nebulizing with Dos Medical nasal saline and xylitol ensures optimal rinsing and the degradation of the biofilm of bacteria. The biofilm is a slimy layer produced by bacteria to adhere better to human tissue. In addition, the biofilm of bacteria also protect bacteria against immune responses of the human being, and to antibiotics. By doing so, bacteria create an improved survival for themselves. Xylitol is also, in small amounts, created by man himself. The added value of xylitol is well known in dentistry. Therefore chewing gum with xylitol is developed: bacteria stick to the teeth (dental plaque) is neutralised by chewing gum with xylitol. For an extra fresh feeling after rinsing with Dos Medical nasal saline with xylitol, a hint of mint is added.
