In the mud therapy treatment, the thermal mud is gradually applied to the skin at a temperature of around 40°C generally over the entire body (with the exception of the front thoracic area and head) or partially over a limited area. The duration of mud therapy varies from 15 to 30 minutes, depending on the treatment. After the mud bath, the patient is washed with a hot shower and immersed in a thermal bath at a temperature of approximately 38°C for a period of 8-10 minutes. The mud used in our factory is made up of a solid element (clay), a liquid element (salt-bromine-iodine water) and a biological element (microorganisms). It appears as a dark gray mush made up of very fine silt, hot at a temperature of 60 to 70°C and slow to cool. The biological and therapeutic effects are multiple: anti-inflammatory, analgesic, muscle relaxant, eutrophic action, stimulating action on numerous metabolic processes. In addition to having a beneficial effect on the whole body in general, the salt-bromine-iodine muds find a primary indication in the vast field of disorders of the musculoskeletal system and safe indications in many pathologies of other organs and systems. Mud therapy is indicated for the following pathologies: OSTEOARTHROSIS, OSTEOPOROSIS, EXTRA-ARTICULAR RHEUMATISM. The agreement with the National Health Service allows everyone to benefit of one agreed cycle of thermal therapy for year, with the exception of some categories who can benefit of two cycles by presenting a prescription from their family doctor or pediatrician.
