Endlich Frühling

Der Winter ist zwar vorbei, aber auch im Frühjahr kann es einen noch erwischen: Die Nase beginnt zu laufen und ist verstopft, man hat Fieber, Kopfschmerzen und ein Druckgefühl hinter der Stirn oder im Wangenbereich. Sinfrontal® hilft bei Entzündungen der Nasennebenhöhlen, öffnet die Nase und befreit den Kopf.

Finally spring

It is not winter anymore, but in spring it can still catch you: The nose starts to run and is blocked, you have fever, headaches and a feeling of pressure in the forehead and cheeks. Sinfrontal® helps alleviate sinusitis, opens the nose and your head.

No desire for nothing?

Hyperforat® can help to overcome a period when we are feeling low and the inner drive is lacking. Hyperforat® is available in tablets, fluid tincture or as a fluid dilution for injection.
