AllerRin BIOSTERINE® Nasal Spray is a rhinologic isotonic solution with a physiological pH, indicated for the treatment and prevention of symptoms related to allergic rhinitis.
Thanks to the presence of hyaluronic acid, the nebulized rhinologic solution creates a film in the nasal cavities, with a barrier effect protecting the mucosa from contact with environmental allergens. The protective film-coating effect, combined with the presence of Biosterine® (phytocompound consisting in Tulsi, or Holy Basil, and Salvia Officinalis, titrated at 40% in Rosmarinic acid) and with extracts of Perilla, Caper, Nymphaea odorata and Red Tea, has decongestant, emollient and soothing properties; it also relieves discomfort caused by irritation and inflammation; owing to the isotonicity of the formulation it contributes to normalize the physiological functions of the nasal mucosa. Due to the presence of vegetable Glycerin, AllerRin Biosterine® also promotes reestablishment of the right level of hydration of the mucosa, limiting its hypersensitivity.


Sodium hyaluronate, Biosterine®: Tulsi or Holy Basil (Ocimum sanctum) dry extract and Sage (Salvia officinalis) titrated at 40% in Rosmarinic acid, Perilla (Perilla frutescens) extract, Caper (Capparis spinosa) extract, Nymphaea odorata extract, Red tea (Aspalathus linearis) extract, vegetable Glycerin, Demineralised water, Sodium Bicarbonate.
