Nitric water is a mineral water that contains nitrogen. The formation and distribution of nitric water is closely related to the regional geologic structure. Nitric water usually forms during groundwater circulation in a closed deep environment associated with large faults during intense neotectonic movements. It flows to the ground surface along regional faults. It is a basic and common type of medical hot mineral water and is effective for therapeutic use, particularly for treating diseases associated with the cardiovascular system, limbs, and gynaecological, skin and endocrine diseases (hyperthyroidism).
