Stamatin is a product that helps the body fight viral infections. It further strengthens immunity and thus prevents the development of infections.  

The all-natural formula of Stamatin is especially suitable for strengthening the immune system during the autumn-winter season. Stamatin can be taken both in the acute phases of infection and for prophylaxis.[6] 

Radix Isatidis is the root of the Chinese herb Isatis Tinctoria, well known in Chinese traditional medicine for its strong antiviral action[1,2]. It blocks the attachment of viruses and contributes to body cleansing and rapid healing. 

African geranium (Pelargonium sidoides) is a herb with pronounced effect in bronchitis, sinusitis, colds and other respiratory conditions[3, 4]. It helps fight bacterial infections and facilitates expectoration.  

Zinc and Vitamin C have an immune-boosting and antioxidant effect, increase the body’s defenses and accelerate recovery.[5]
