In the hills just south of Rome, lies the small medieval town of Fiuggi The obscure conglomerate of stone buildings gained renown as early as the 1300s, when Pope Boniface VIII claimed his kidney stones had been healed by the mineral waters that gushed forth from the nearby Fiuggi spring. Two centuries later they relieved Michelangelo of what he called "the only kind of stone I couldn't love." Soon the miraculous acqua di Fiuggi was being sent in bottles to all of Europe's royalty.

Fiuggi water gushes out from two thermal baths and one of these: the Boniface VIII Spring is where Italians go to “take the water”. The fountains from which healing spring water is obtained are set within a large park. Locals and tourists alike used the surroundings as a meeting place for centuries to chat and discuss the news as they sip from the spring.

Fiuggi water is a natural, oligomineral water that pervades tufaceous (calcareous and siliceous rock deposits) hollows beneath the spas of Fiuggi. The scientific effect is a filtering action that purifies and reduces mineralization in the water, while creating a potent diuretic chemistry. Fiuggi is prescribed in Italy for expulsion of kidney stones, and supposedly inhibits their formation; it is also prescribed during preparation urinary calculosis procedures and post-op treatment. In all, there's little question that Fiuggi is beneficial for the kidneys and urinary tract, and it is also effective against uric acid in general, which is the basis of gout and uratic arthropathies. The water has a very acidic pH of 6.8 and a very low TDS of 122. Fiuggi was the official water of JUBILEE 2000, and it is rumored to be the choice at the Vatican.
