In our locations where no natural thermal mud exists, like in Marienbad (CZ), peat has been used as a natural healing source over 200 years. Peat contains a considerable amount of organic matter (from vegetation growing on peat bogs and moorlands), whereas mud is mostly composed of various mineral substances. The biologically active organic substances stimulate the formation of new capillaries in the tissues thus improving their blood supply and subsequently their metabolism and function. The organic acids contained in the peat stop the growth of bacteria on the skin surface. Peat has been effectively used for the treatment of infertility and normalisation of sexual dysfunctions in both men and women. Peat packs may also be applied in the treatment of psoriasis or atopic eczema.
