The Technique

Medistus® Antivirus is a medical device product with a novel impact. Kistosyn® 100 extract contains polyphenols and forms a protective film over the mouth and throat mucous membranes. This protective barrier leads to a physical (mechanical) barrier against viruses and bacteria which prevents their penetration into body cells and their further propagation. In addition, cough and dry cough is alleviated by the drug gum arabic. Due to this physical effect resistance development is not possible.
