Herbal medicine and the health-promoting use of plants are centuries old. If medicinal plants are used skilfully, they can have a harmonising, stimulating, strengthening or inhibiting effect on various processes in the human body. The use of a whole plant creates a spectrum of effects in which it is not the quantity of individual active substances that matters, but the harmonious synergistic composition of all active ingredients.
The secondary plant substances are of particular value. Among other things, they serve as a defence against pests and diseases and regulate the growth of the plant. Antioxidant polyphenols, carotenoids and flavonoids are among the best-known groups of secondary plant compounds.
In order to survive, plants have the ability to adapt themselves to the environmental or climatic conditions they live in. Plants native to swamps for example have created a defence system against fungi, whereas plants that are found in higher regions are able to store minerals and amino acids. This ability to adapt to all sorts of circumstances requires a wide spectrum of active substances in every plant: vitamins, minerals, trace elements and amino acids. Substances that are very useful for the human body as well.
