SinuSyn is composed of Glycerol and extracts of Camellia sinensis, Vaccinium myrtillus, Vaccinium macrocarpon and Sambucus nigra. Sinusyn is a viscous and osmotically active hypertonic solution for nasal spray. SinuSyn forms a film over the nasal mucosa and sinus openings. The osmotically active film instantly attracts hypotonic fluid present in the deeper parts of the mucosa and creates a stream of hypotonic fluid from the inside outwards outside. This mechanical effect detaches and drains all contaminants present in the nasal cavity and decongests the nasal passage.
