Merano water as a remedy for constipation:
An additional element that makes the Merano basin valuable is the excellent drinking water that flows from the slate rocks. It is not as cold as that which flows from the limestone rocks, which easily causes a fever, and it is not as warm as that of the mossy areas. The source in valley Naiftal develops a considerable amount of carbon dioxide. The water also has three different degrees freshness and sweetness depending on whether you taste it in Merano, in Obermais or in the valley Naiftal, at the source itself.
