To learn about thermal mud ripening it is necessary to know that the mud of Abano and Montegrotto Terme is composed by three parts: a solid one (the clay), a hydro-mineral part (sodium chloride bromine and iodide iperthermal water) and an organic component of micro-organisms and biomaterials.
The clay used in the SPA (also known as “pure mud”) is extracted from the thermal lakes in Lispida and Arquà Petrarca, both at the foot of the Euganean Hills.
After a phase of filtration and purification, the clay is laid in special tanks and covered by current sodium chloride bromine and iodide iperthermal water in order for it to mature during a period of 50-60 days. This time laps is called maturation and it occurs in an open-air habitat where the ecosystem that surrounds the mud-tanks has an impact on the clay, leading to chemical and physical modifications and allowing bacteria, protozoa and micro-algae to develop a sort of “colonization” on the mud.
The mud is enriched by precious active principles derived from the metabolism of the micro-algae flora. Thus it increases the volume of rehydration, it increases its thermal insulating capacity and, in its composition, chemical fractions with high anti-inflammatory properties and lacking of side effects, appear.
The temperature and chemical composition of the water in the basins of Terme Euganee has a fundamental action for the development of the microflora and the maturation of the mud. The environment and the specific components of the territory are essential and strictly specific for the thermal mud maturation, that only after this process becomes effective as an anti-inflammatory therapy.
