I looked to see what it might be by google and ended up with several spa pages, none of which told me. Some had volcanic material mixed with water making the same claims.
What I did find:
These mineral springs and mud baths have been used for millennia and been claimed as curative.
The mud and mineral baths will prep your muscles to let go so your massage therapist can go deeper, releasing even more tensions and stresses, allowing you to leave the spa with a totally rejuvenated mind and body!
“The mud bath, because of its volcanic ash, has healing properties that are detoxifying, so it pulls impurities out.” Teranchi says the combination of volcanic ash and Calistoga’s natural geyser water can improve circulation, restore sore muscles, and even treat skin reactions like eczema.
Plus, when the ash is combined with water, it can work as a natural exfoliant, much like over-the-counter clay masks.
A mud-bath therapy study from Silene Springs at Italy’s Chianciano Spa. Scientists, hoping to understand the efficacy of those antiquated mud baths’ “healing properties,” devised a test around a group of patients suffering from osteoarthritis. After a year of observation, during which half of the patients enjoyed a handful of mud bath treatments, the scientists emerged stunned — the results proved that mud-bath treatment actually works. The group that enjoyed a dip in Italy’s famed mineral water mud baths were in luck: The treatment “remarkably improved the clinical conditions of patients with knee arthritis and significantly reduced the frequency and severity of symptoms.”

Claims, but not a whole lot of science out there. Heat and earth minerals, doing things with the skin, are all good and curative. Relaxation is curative, natural balance instead of chemicals and clothing are healthier. This is one more activity to add to the list of associated activities.
It is supposed to be good and curative for a body to be wrapped and buried in soil for earthing and grounding, so....
It is harmless, fun, and healthy activity. It is relaxing and cleansing. I’m always up for being naked at a hot spring.
