The Thermal Spring

Features and Therapeutic Properties

The Etruscans were well-known in the ancient world for their incredible expertise in the medical art and particularly for their knowledge of the properties of officinal plants and of the therapeutic power of thermo-mineral waters, of which the Tuscan region is still very rich. The Etruscans had a profound knowledge of the healing properties of these sacred springs – each one dedicated to a different god – which the Romans, after conquering these lands, turned into large thermal facilities.

Spa Medicine and Wellness

Petriolo thermal waters come directly from its spring, located near the Farma stream, rising to surface level at a temperature of about 43°C. From a technical viewpoint, based on their mineral components, they can be classified as hyper-thermal waters, containing bicarbonate, sulphate, calcium, magnesium, iodine, bromine, sulphur and carbon dioxide.

These waters, renowned since ancient times for their many and proven healing properties, are useful in the prevention and treatment of various pathologies, particularly those involving osteoskeletal, tendon, skin and vascular issues. The thermal water fitness and kinesitherapy are also very effective as rehabilitation.

Recent studies have also proven the effectiveness of thermal treatments with this kind of waters to help the body balance the production of substances regulating moods and the wake-sleep rhythm. This property is central to the sense of well-being experienced after a Spa treatment and it can appropriately be defined as “Spa well-being”.
