Since thousands of years, herbal products were used for medical purposes in old cultures. The present trend to re-discover the medical potential of herbs started to grow with the general awareness of the medical hazards of several chemical pharmaceutical preparations. Similarly, for several decades, antibiotics, Coccidiostat and other chemical feed additives were massively used in animal husbandry. However, due to their negative impact on consumer health, they were banned in many countries.

The number of commercially available herbal products increases rapidly in the markets worldwide and are expected to overtake the number of pharmaceuticals of chemical origin in food sector in the future.
