摘要
Thermal medicine offers an original approach to health that is not only based on treating symptoms. The major advantage of thermal medicine is based on the overall support of the disease, providing prevention, alleviation and treatment of many diseases (rheumatism, bronchitis, skin diseases, etc). In order to get the best possible results by thermal treatments, regular and accurate analysis of the thermal waters of the hot springs is often necessary. This article has a scientific objective for the development of fundamental knowledge needed to better control the hydrogeochemical hot springs in northern Algeria. This study will be addressed by conventional chemical analysis of major chemical elements found at water points (hot springs) in northern Algeria. The results are obtained in the form of semi-logarithmic graphs (Schoeller and Berkallof) and rhombic (Piper).
