It is basic and brilliant!
It is basically hot and cold towel on your chest/abdomen and back with a little sine wave stimulating various parts of the nervous system.
Brilliant because it uses and balances “your” own nervous system, works over “your” stagnant blood and helps circulation, and uses “your” own detoxification pathways without causing harm (lungs, skin, bowels, liver, kidneys).
In a way a generic treatment, but also a very “individual” specific treatment.
