In this symposium, author's opinion about the balneotherapeutic practice of the digestive disorders was expressed. 1) At the beginning of this speech, author's fundermental studies on this theme hitherto were shortly summerized as premise. 2) According to these conclusions, it is very neccesary for the indication of the balneotherapy of digestive disorders to classify thermal springs (not only thermal water, but also hot spring place included) into two groups: one is so-called medicinal or therapeutic spring (“Heilquelle”) and the other is “recreation hot spring” (“Erhohmgsquelle”) (that is hot spring for maintenance and improvement of health). 3) The former is the hot spring intend to medical treatment of digestive diseases and the latter is that intend to health preservation, health promotion, normalising or adjusting the digestive dysfunction. 4) From this point of view, the author mentioned my own opinion concretely and practically about the indication of both “Heilquelle” and “Evholungsquelle” for the digestive diseases and disorders.
