Sinomarin® is a 100% natural, clinically proven nasal decongestant. It is a hypertonic solution of seawater (2.3% NaCl), rich in beneficial marine ingredients (mineral salts and trace elements). Sinomarin® relieves nasal congestion and sinus pressure through the natural mechanism of osmosis. Sinomarin® helps to hydrate and cleanse the nasal passages, eliminating accumulated mucus, crusts, dust, debris, pollutants, allergens and infectious agents. Properties: Relieves nasal congestion by reducing swelling of the nasal mucosa (through osmosis). Thins mucus secretions. Helps restore the natural function of the nasal mucosa. Cleans the nasal cavities of accumulated mucus, crusts, dust, debris, pollutants, allergens and infectious agents. Moisturizes the nasal mucosa and relieves nasal dryness. Sinomarin® improves quality of life by relieving symptoms associated with nasal congestion (e.g. nasal itching, sneezing, cough, sinus and ear pressure, sleep disturbances). Sinomarin® is recommended: For all cases of nasal and sinus congestion, e.g. rhinitis (infectious or allergic), sinusitis, common cold and flu. In cases where decongestant drugs are contraindicated (e.g. pregnancy, breastfeeding, thyroid disease, hypertension, heart disease, diabetes). To enhance the effectiveness of decongestant drugs and reduce their use. To prevent secondary ENT infections and complications such as otitis. To promote recovery after endonasal surgery. For daily hygiene (e.g. in polluted environments). For hydration in dry environments.
