For colds and sinusitis The sinusitis nasal spray not only helps with a simple cold, but also with inflammation of the adjacent sinuses. The thick nasal mucus is liquefied and simultaneously removed along with disease-causing viruses and bacteria. In addition, a protective film is formed on the nasal mucosa, reducing the pressure and pain sensation in the sinuses. Application: 2-3 times a day, up to 3 sprays into each nostril (more often if necessary) until full recovery.
