Mode of Action

A cold comes three days - stays three days - leaves three days.

Colds are caused by more than 200 different respiratory viruses.

Like a burr to textiles cold viruses bind to the surfaces of the upper respiratory tract.

Then the infection starts. It is time to interfere!

Sprayed into the nose Carragelose® creates a protective layer in the nasal cavity that helps to reduce the spreading and proliferation of the common cold virus.

The clotted viruses leave the body via the natural route - the cold might not even come, stay shorter or leave faster.

No Virus – No Cold – Naturally achieved

Safety & Efficacy

The safety and anti-viral effectiveness of Carragelose® have been established in several clinical and non-clinical trials. Three double-blind, placebo-controlled clinical trials confirmed the anti-viral effectiveness, a significant reduction of the duration of the disease, a significant reduction of viral load and a reduction of relapses.
