The knowledge about usage of plants for medical purposes has always been one of the greatest treasures of any civilisation. The very important task for scientists working on medicinal plants is to preserve the primary med-botanical knowledge, commonly called folk medicine, before, as it was dramatically put by R.E.Schultes (1978), it gets buried together with the cultures who created it. Scientists from numerous countries work on gathering and organising the information widely spread in literature concerning the effect of various plants on human health. One of the plants is Carum carvi.
