The Kuhne friction sitz bath and 'New Science of Healing'
- All disease has a single cause, the accumulation of 'foreign matter' (a self-poisoning of the body), and therefore a single cure: there is a unity of disease and a unity of cure, achieved without medicines and without operations. refuted
- The friction sitz bath (Sitzreibebad), in which the bather sits in cold water and gently rubs the external genital region with a cloth for ten to sixty minutes, dissolves and moves the accumulated foreign matter toward the bowel for excretion, restoring health and vitality. refuted
- Internal disease can be read from the face and body: deposits of foreign matter produce visible swellings and changes ('encumbrances') that reveal the seat and degree of disease in advance, an 'ante-diagnosis' enabling one to foresee and forestall any ailment. refuted

Kuhne’s intervention was a drugless regimen built on a single procedure and a single idea. The procedure was the friction sitz bath (Sitzreibebad): the patient sat on a footstool in a tub of cold water filled to the level of the seat and gently rubbed only the external genitals with a coarse cloth for ten minutes to an hour, no other part of the body touching the water (The New Science of Healing). The idea was that all disease is one thing, the accumulation of “foreign matter” in the body, a self-poisoning, so that one method of drawing that matter out, toward the bowel for excretion, could cure everything “without medicines and without operations.” Around the bath Kuhne prescribed a vegetarian diet and abstention from salt and sugar, and he sold an adjunct method, facial diagnosis, for reading the seat and degree of disease from the face and body in advance.
The regimen was delivered through Kuhne’s fee-charging Leipzig practice, through his books (which he published through his own house, Verlag von Louis Kuhne), and through water-cure establishments abroad that took up his method. The books were the principal vehicle: Die neue Heilwissenschaft and the 1897 Facial Diagnosis were translated into English and reached a broad international readership who applied the method at home.
No controlled evidence ever supported the system, and the claims are mechanism-only. The single-cause doctrine is a form of the intestinal-autointoxication theory that medicine examined and discarded in the early twentieth century (Whorton, 2000; Sullivan-Fowler, 1995; Bested et al., 2013), and the morbid-matter image behind it is pre-modern humoral pathology (Encyclopaedia Britannica, “Humour”). Cold-water bathing has real but non-specific physiological effects and does not expel a material disease-cause; facial diagnosis is a physiognomic method the book itself relates to phrenology. As with Priessnitz’s cold-water cure and the dietetic-vitalist regimens of Hufeland, Fletcher, and Bircher-Benner, several components of the surrounding regimen were harmless or mildly sound, so what failed was the doctrine and the specific mechanisms, not every part of the daily routine.
