Sambucol® is a supplement developed over 20 years by a world renowned virologist – a scientist who is an expert in viruses - to exploit the health-giving properties of the plant. Sambucol® is a unique extract of black elderberry (Sambucus nigra), a fruit whose natural health-boosting properties have been recognised since the dawn of civilisation. Medical science has only recently discovered the likely basis for the elderberry’s health-giving reputation. Studies have shown that elderberries are unusually rich in the phytochemicals known as flavonoids. and among all fruits, elderberries are the most concentrated source of anthocyanins, a class of flavonoids that act as powerful antioxidants to boost the immune system and protect the body’s cells from harm.
