Unique Benefits

Castéra-Verduzan Thermal Spring water is a one-of-a-kind water

It is mainly due to its sulfur-rich composition that it offers naturally amazing therapeutic properties. 

Over its travel through the geological layers, it becomes loaded with minerals and trace elements. Composed by 1301mg/l of dry residual at a 180° temperature, this sulfated water blend of calcium and magnesium provides unique benefits specially adapted to the oral well-being as it is demonstrated by a lot of research works:


  • Its content of minerals and trace elements gives it soothing and remineralizing properties for the teeth and the gums.
  • Its high oxygen level allows to neutralize strict anaerobic germs responsible of periodontal diseases and of bad breath.
  • Its basic pH (pH = 8,1) obtained through a unique patented process regulates mouth acidity, a major factor that causes oral ecosystem imbalance.

Directly drawn from the source, this exceptional thermal water, 100% respectful of the oral flora, is analyzed every day in the laboratories before being used on the BUCCOTHERM® production plants.
