Kneipp Cold Time Bath Crystals with precious eucalyptus essential oil develop a pleasant aroma and give you a soothing bathing experience during the cold season. The high proportion of naturally pure thermal brine salt is extracted in Europe's only remaining pan boiling plant, Saline Luisenhall, from pure natural brine, which is constantly enriched at a depth of 460 metres from the salt deposits of a 250 million year old primeval sea. The naturally pure brine is free from chemical additives and environmental influences.
