Relieve your stuffy nose without the help of preservatives or pharmaceutical substances and try Rhinaris Sinomarin-for Adults. This is a Hypertonic Nasal Wash with an anatomically designed nasal applicator and a medium spray. Rhinaris Sinomarin contains naturally sourced hypertonic sea water, which means this solution has a greater salt content than a human body. This formula ensures your nose will receive an optimal cleaning as the sea water, trace minerals, and mineral salts remove excess mucous to improve breathing.
