This books needs an introduction because of the words like,Drainage; Drainer,Tubercular conditions,etc. which are new to the Homoeopathic of India. The drainage is one of the most important system of Homoeopathic treatment among the French homoeopaths. In short, drainage nothing but the use of remedies having ephemeral action in order to help in the eliminatory functions of the antipsoric remedies. The helping remedies are generally the complementaries and antidotes of the principal basic remedy. The antidotes are used as an umbrella working as a check,in the too dangerous eliminatory function of the basic drug,which may cause aggravation of the disease. The word ,tuberculinic, tubercular conditions, have been introduced into homoeopathy by Dr.A.Nebel of Lausanne who made serious investigations on tuberculines. It is Dr Nebel who says that ,If the word Psora dose not merit to be maintained only to honour the memory of Hahnemann,we may replace it with Tuberculinism ,. Some explanation are required about the above two facts in order that the principle of drainage and canalisation and identity of tubercular condition with Psoric miasm may not be misunderstood by the orders of this little book. I have,therefore,given in the summary of tow lectures of Dr.Fortier Bernoville,one on ,Identity of Psora and tuberculinism; delivered in Glasgow(1936) and the other on principles of Drainage and Canalisation.

Identity of Psora with Tuberculinism: if the name psora dose not merit to be maintained in order to honour the memory of Hahnemann, we may replace it by the word tuberculinism,.It is thus Dr.A.Nebel expressed himself in 1934.This opinion has become very much current among the French homoeopaths. It should be supported by 1.Clinic, 2.Laboratory work and 3.Homoeopathic therapeutics.

Let us see first of all what Psora of Hahnemann is? It is according to Master the most common ,the most contagious and the most stubborn miasm.He called,itch,not only to lesions caused by Sarcoptic but also to all chronic,when suppressed, of causing numerous and varied metastasis.He shows by the help of numerous documentaries that the Psora may be succeeded by ,Suffocating catarrh, hydropsy, pleurisy, all sort of cough and hemoptysis, meningitis, ascites, hydrocele,jaundice,deafness,diabetes, haemorrhoids etc;. The researches of Hahnemann has been singularly illuminated by the researches of Richet,Vidal and A.Lumiere. What do we mean by tuberculous virus according to the works of modern biologists?

After discovery by Koch the bacilli of Tuberculosis which Villemin foresaw, numerous kinds of alcohol or acid resistants have been discovered. At that time, one did not admit the existence of tuberculosis until and unless, Koch’s bacilli were detected by the microscope in the sputum. At present, the discovery of tubercular ultra-viruses, which are capable to cross through the placenta (Hauduroy, Arloing, Dufour) and cause contagion in utero (Calmette, Valtis, Negre, Boquet) has completely exploded the theory of Koch’s bacilli. The important of cuti-reactions which were then completely unknown has now become very important. Thus heredo-tuberculosis has become a reality like that of heredo-syphilis, which proves the theory of Psora.

We have then two theories: That of Psora and that of Tuberculinism. Now we will show their identity:

Clinical proofs.

The works of Bezacon and Jacquelin (Congress on Asthma, 1933),m show the close relation of Asthma with tuberculosis. The children of asthmatics very often become tubercular or inversely. It is also seen that asthma develops in chronic tubercular patients cured on in persons having calcified cavities.

Poncet has long ago described a form of Rheumatoid arthritis of tubercular origin. Numerous forms of arthritis are now attributed to the tubercular viruses. It is this conception which has led to the use of Gold in cases of rheumatoid arthritis, with frequent success. Let us note that the reaction of Vernes- resorcine is very often positive in these affections.

The tubercular form of salpingitis has a tendency of becoming more important. Pure or gonorrhoeal forms are associated. Same thing is considered in appendicitis (Caecal tuberculosis).

Some good results are obtained by anti-tubercular treatment in several other diseases. Asthma with Tuberculines (Jacqueline), treatment of rheumatism by chrysotherapy, methilic antigen or allergine.

Kent has shown alternate states of dementia and tuberculosis. Some anxiety neurosis are also attributed to tuberculosis.

In endocrinal troubles, tuberculosis is of great importance with syphilis (Addison’s disease, diabetes, Basedow’s disease etc.)

Systematic study of personal hereditary antecedents in psoric patients proves, alternate of diseases, which shows that there is predisposition to tuberculosis.

2.Laboratory results: The cuti-reactions to Tuberculines are positive in 97 Percent of cases in adults. Their intensity varies following anti-tubercular treatment by the application of diluted Tuberculines.

Vernes resorcin reactions which are positive in tuberculosis in evolution, is positive in rheumatism, which leads one to think that it is related to t tuberculous infections.

Pulmonary radiography shows in almost all individuals more or less discrete and sclerosed lesions of chronic tuberculosis.

This last information is confirmed by the autopsies in course of which the extreme frequency of calcified tubercles are discovered.

3. Arguments from Homoeopathic therapeutics: It is first of all necessary to take some cases which will show us in our psoric patients, the filiation with tuberculosis. In such cases, the addition of a diluted Tuberculine to the treatment is indicated. We know, on the other hand that in the majority of chronic cases, it is only after the use of a Tuberculine that we get final cure. The aggravation, almost constant in patients who are given Tuberculine at the beginning of the Treatment, has led Dr. A. Nebel to think that Psora was identical to tuberculinism. It is in order to avoid the aggravation, he found out his method of drainage. These aggravations, are seen in hypertensive, arteriosclerotic, arthritic, venous, uremic patients and in some patients having stones, eczema urticaria. Thus the arthritic diathesis which seems to be on the antipodes of tuberculosis is on the contrary attenuated tuberculinic. These patients have hypercholesterinemia which is nothing but an exaggeration of the defense against the tuberculous virus. Instead of caseifying, they cause sclerosis. The parasitosis are also under the dependence of tuberculin (intestinal worms, colibacillosis).

Finally if the Hahnemannian description of psora is compared with the pathogenesis of Tuberculinum, one will be astonished to see the analogy of the important symptoms. Dr. Renard has besides shown that Psorinum and Tuberculinum are interchangeable.

Therefore Psora seems to us clearly the ensemble of hereditary tubercular manifestations.

How can we explain the identification of psora with tuberculinism?

J. Sedillot has explained the role of hepatic insufficiency causing different manifestations, which apparently different and autonomous. He explains how the residues (nitrogenated) incompletely transformed by the weak liver are over-saturated in the blood serum where it flocculates either during a momentary overcharge of the liver (faulty diet), or during an anaphylactising cause (pollen, emotion etc.) These flocculates are phagocited by the monocytes, which, not being able to divest themselves of their renal epithelial burden, are eliminated through points where congestion of blood favours the exudation. In babies it is the skin,. the fragile barrier. it is very often irritated specially that of the orifices, causing oozing lesions which becomes secondarily infected and gives birth to oozing eczema. When late on the skin will become hard we, will find furuncles and urticarias; then come different tropisms: asthma during thee first bronchitis. Later on the favourite points of elimination will change and tropisms will be modified.

This hepatic deficiency, which remained undetermined to Sedillot, seems to us to be the fact that the foetus is contaminated by the tuberculous virus (Bernard). Because of the constant arrival during long months, of ultravirus into the liver through umbilical chord and vitellines, an abnormal proliferation of the conjunctive tissues of that organ is caused, because it is the tissue (reticulo-endothelial) which is precisely meant to produce the monocytes which will phagocyte the flocculates.

Thus we understand: 1.The identification of psora and tuberculinism. 2 Multiple psoric manifestations and their polymorphism.

In Summary:

Psora is therefore the direct consequence of tubercular affection, very often hereditary., sometimes acquired in lower age.

Its characteristic are 1. Alternance, 2. Endocrinal troubles, 3. Vago-sympathetic disturbances, 4 Troubles of tissue tonus, 5. Cutaneous tropism, 6 Parasital tendency, 7. Predisposition to contagious diseases, 8 Suppurative tendency, 9 Troubles of mineralisation.

Tuberculinism seem therefore the primordial and primary cause of majority of chronic diseases. It is like a background canvas on which are projected the other secondary manifestations: trauma, shocks, emotional shocks, anaphylactic phenomena etc.

Finally I must add that Kent has called psora “Urschadigung” i.e. the original sin of human beings. As such we may describe and understand psora in different manner. We call psora as the scourge of human civilization which is making man prone to all sorts of diseases. If the reader feels himself interested in my exposition of psora as the scourge of civilization, he may refer to my article “Homoeopathy in search of the total man” published in the Hahnemannian Gleanings, January No.1, 1970.

Now let me speak something about the Drainage and Canalisation as Dr. Fortier-Bernoville understands it.

Drainage and Canalisation in Homoeopathic therapeutics: It is to Dr. A. Nebel we owe the idea of Drainage and its corollary Canalisation, one of the most important principles of Homoeopathic therapeutics. Drainage was practised since Hippocrates up to our time by Rademacher, by Hahnemann himself and finally by Burnett.


When we speak of drainage, we should distinguish well the theory from the practice. In order not to run the risk of being reproached as builders of purely theoretical systems, we will speak here only of the results obtained from the practice of drainage and canalisation, the theory having, in our opinion, only explanatory value, 2 of simple orientation.

However, we should give a theoretical definition of drainage before speaking about its practical application.

The theory of drainage is intimately bound up with the idea of making the organism free from morbid energies, If we understand an organism as composed of many spheres, we will see that it is necessary to give one or more medicines acting simultaneously on the successive organic spheres.

But a single remedy, even highly diluted cannot always act in a sure and complete manner on all the spheres and generally the high dilutions help to obtain a superior action on the most subtle and higher planes, particularly on the sphere of sympathetic system.

It is therefore necessary to help the Similimum by a judiciously selected remedy which is a Simile.

It is said that in each pathological case there exists in Homoeopathy, a single Similimum and many Simile and the first idea that comes to mind is to apply uniquely the Similimum with the exception of Simile remedies that seem to be palliatives.

In reality, very soon one understands that the rigorous application of the Similimum remedy is not always followed and is not necessarily followed by an amelioration. If we can prepare the organism by the application of a remedy called satellite, or the remedy, which by analogy, has the symptoms culled from the patient, it happens very often that the Similimum may be applied afterwards WITHOUT AGGRAVATION and it seems even to act more rapidly and more deeply.


The theory of drainage is, therefore, a theory of purification. Besides, the term Drainage so often used in surgery, is understood better when one is only on the material plane. There is no doubt that when there is a suppuration in the organism, it is necessary to eliminate the formed pus, except in some cases where it is possible to obtain a complete resorption.

It is therefore, necessary to purify the organism of the patient by eliminating the toxin. It is necessary to drain.

But drainage considered from the point of view of practice is much more important than from the point of view of theory. THE DRAINAGE IS BEFORE ALL A PRACTICE JUSTIFIED BY RESULTS. The theory of drainage like all theories is seducing but it is rather easy. We need not find out up to what point it may be true according as one represents it in such and such manner, but it is necessary before all to insist on the fact that it is fecund and that this fecundity is the only justification that we require. THE PRACTICE OF DRAINAGE CONSISTS IN FOLLOWING OR IN PRECEDING THE PRINCIPAL INDICATED REMEDY BY THE APPLICATION OF ONE OR MORE SATELLITE REMEDIES WITH THE AIM OF FACILITATING THE TOXIC ELIMINATION IN A GIVEN MORBID STATE TO CHECK MEDICINAL AGGRAVATION AND TO OBTAIN MORE RAPID AND SURE RESULTS.

Experience shows that the systematic and rational application of antidotes and complementaries of Hahnemann, side by side with the principal remedy forms the real key to the practice of drainage. It is thus that Dr. Nebel has shown to us by attractive examples the value of drainage, He has for example shown to us that before calcarea carbonica is applied to a patient who has its symptoms, one may obtain good results and can check all aggravations in tubercular patients, by giving at first Pulsatilla which is a real drainer of Calcarea carbonica.

In other cases where there is an acute and temporary febrile condition Belladonna may be a satellite of Calcarea carbonica and which is necessarily indicated before the ground remedy. Sometimes the satellite may be Dulcamara or Chamomilla.

Let us now speak of Canalisation.

We should also understand Canalisation from the theoretical and practical point of view.


It appears then that the principle of Canalisation is a corollary of the principle of Drainage. To canalise means to DIRECT THE ACTION OF A REMEDY IN SPACE AND AS WELL AS IN TIME. Canalisation consists in the real study of the physiopathologic action of remedies.

To canalise is to direct the effects of a medical substance and to orient its action. When we speak of the local elective action of a remedy, it is necessary to speak precisely here that most of the remedies may have, from spatial point of view, some elective actions, either on the tissues, on the organs, or on the topographic region oriented along the nervous system or very often according to a metameric segmentation. There exists, therefore, three kinds of local elective actions which rule canalisation. In practice to give a satellite which will have for aim to canalise and orient the effects of the principal remedy; that action becomes naturally in part a real check. When we give to a patient a dose of the high dilution of Sulphur according to the symptoms (while the patient has also the tendency to suppuration), we may do good to the general condition, but at the same time we may have some dangerous local effects, by increasing the tendency to suppuration. If on the contrary, we know how to canalise the too centrifugal, violent and general action of Sulphur, on such and such parts of the organism, we will surely obtain good action of this remedy. Nux vomica for small intestines. Aloe for the rectum etc… In this case we may say that these different remedies are the Canaliser of Sulphur, because they canalise its effects and orient its action and help to obtain more sure and rapid results from the curative point of view.

The traditional homoeopaths are wrong to believe that the strict observation of the law of Simillars, without trying to understand, it, is always good for the patient. The pathogenesis are really, says Dr. Nebel, some physiopathologic studies of remedies. We should understand the homoeopathic remedies as having physiological actions which may not in practice always give curative results. CANALISATION IS THE ART OF DETERMINING THE ORIENTATION OF THE PHYSIOPATHOLOGICAL ACTION OF THE PRINCIPAL REMEDY BY THE PRESCRIPTION OF THE ONE OR MORE SATELLITE REMEDIES CLEARLY DEFINED.

Now we understand that the rational direction given to Homoeopathic treatment by observing the law of similars in a really scientific sense will give to him who will understand its principles, an uncontestable superiority on a too traditional Homoeopathy, practised without taking into account the Drainage.

Finally I must add, if the readers want a detailed study of the Principles of drainage and canalisation, I will ask them to see Hahnemannian Gleanings, March, 1970, p. 109.* or What we must not do in Homoeopathy-Jain Publishers.

I have included in this book an article on the drainage of the respiratory system. There the readers will find how the remedies are topographically distributed according to their elective actions. The readers will find some more information about drainage in that article.

Mauritius Fortier-Bernoville

Mauritius (Maurice) Fortier Bernoville 1896 – 1939 MD was a French orthodox physician who converted to homeopathy to become the Chief editor of L’Homeopathie Moderne (founded in 1932; ceased publication in 1940), one of the founders of the Laboratoire Homeopathiques Modernes, and the founder of the Institut National Homeopathique Francais.

Bernoville was a major lecturer in homeopathy, and he was active in Liga Medicorum Homeopathica Internationalis, and a founder of the le Syndicat national des médecins homœopathes français in 1932, and a member of the French Society of Homeopathy, and the Society of Homeopathy in the Rhone.

Fortier-Bernoville wrote several books, including Une etude sur Phosphorus (1930), L'Homoeopathie en Medecine Infantile (1931), his best known Comment guerir par l'Homoeopathie (1929, 1937), and an interesting work on iridology, Introduction a l'etude de l'Iridologie (1932).

With Louis-Alcime Rousseau, he wrote several booklets, including Diseases of Respiratory and Digestive Systems of Children, Diabetes Mellitus, Chronic Rheumatism, treatment of hay fever (1929), The importance of chemistry and toxicology in the indications of Phosphorus (1931), and Homeopathic Medicine for Children (1931). He also wrote several short pamphlets, including What We Must Not Do in Homoeopathy, which discusses the logistics of drainage and how to avoid aggravations.

He was an opponent of Kentian homeopathy and a proponent of drainage and artificial phylectenular autotherapy as well.
