In the ancient Greece, fractures of the limbs were treated by using bandages impregnated with clay mud. Sebastian Kneipp, a Bavarian priest and one of the founders of naturopathic medicine movement specifically recommended poultices that contained clay and vinegar. In Switzerland, clay was often used in therapeutic treatment for tuberculosis. Chest of the patient were painted with hot clay mud and left that way for four hours. Sometimes such therapy led to success.

Sebastian Kneipp started using clay therapeutically and enjoyed significant success fighting against tuberculosis, fever and dysentery. He soon gained many adherents among the major doctors all over Europe. Therefore Kneipp and also a few other significant names in German natural medicine, deserve full credit in establishing that shapeless mass of soil as significant therapeutic source, especially in recent times. Kuhn, Just, Felke and others, used clay in their natural therapeutic procedures. But it was under the influence of the Berlin physician Stumpf, that the use of clay for medical purposes became strongly rampant in the beginning of the last century.
Many simple people have already known about the clay and its properties and healing powers for more than a thousands of years. Ancient Greeks, for example, used mud wraps to bandage and heal broken limbs. But they also used clay together with herbs in many other ways. The Egyptians, for example, painted their deceased with clay because it was considered a natural way of destroying harmful substances and protection against tissue degeneration. Even sick animals were anointed with a mixture of clay and natural vinegar and transferred to the barn with clay mud where they instinctively sought the spot with clay. French troops used clay to protect themselves against intestinal disorders, Russian soldiers, for example, during the first world war but did not go into battle without a bag of clay.

We dig our clay in ecologically clean area in the woods near Komenda, where there is no industry and no farmland for about ten kilometers in every direction.
In this forest the clay is already been mined for 200 years, mainly by potters working in area of Komenda. But for the last 40 years digging is done only and exclusively by Janez Ferjuc - Bolus Cvetka Ferjuc s.p. which also supplies potters and Tile makers in the vicinity. The company is also selling clay intended for coverings and personal medical use. Clay has been checked and. analyzed by the Institute of Public Health in Kranj, University of Maribor- Faculty of Civil Engineering and in referential laboratory Analitical ACME Laboratories in Vancouver.

When the excavation is perfomed industrial clay and clay intended for therapeutic purposes are seperated. Clay is separated according to quality and with regard to the layers of the excavated cave. Approximately 1/10 of the excavated material is the best and clearest clay, which is adequately prepared for consumption. The whole process is performed manually, by means of dedicated tools.
