A useful article about Bowel Nosodes.Full details about Bowel Nosodes

Medicines prepared from cultures of non lactose fermenting bacterial flora of the intestinal tract are called intestinal Bowel Nosodes. They are not the morbid product of disease, but they are classified under nosodes.

B.coli in the intestinal tract perform normal & useful function when the intestinal mucosa is healthy, but any change in the host that affects the intestinal mucosa will affect the balance, and change the biochemistry of B.coli. It should be noted that the primary change i.e. the disease, originated in the host which compels the bacilli to modify in order to survive.

The proving of bowel nosodes were not conducted in the strict Hahnemannian sense, but on clinical observation of the sick person.

1. Dr. Edward Bach (1886 – 1936)

A bacteriologist in London discovered that certain intestinal germs belonging to non lactose fermenting gram negative coli, typhoid group, had a close connection with chronic disease and its cure. These germs are present in healthy and diseased individuals but in the latter case it is pathogenic. He isolated the bacilli and prescribed it for the patient in the form of a vaccine – an autogenous vaccine – and claimed to cure the disease.

Years later he potentised the vaccine according to the Homoeopathic principle, administered and cured so many patients. The first full preparation of clinical proving was done in 1929 by Thomas Dishington on Dysentery co.

In 1930 Bach briefly summarized the clinically derived indication for most of the nosodes.
In 1930 he stopped the research on Bowel nosodes and discovered “Bach flower remedies”.

2. JOHN PATERSON (1890- 1955)

A co-worker of Bach concentrated on this research after 1929. He studied more deeply the characteristics of the bowel flora, especially their behavior in health, disease and in drug provings. He examined more than 20,000 stool specimens and conducted research over 20 years.

He came to the following conclusions: The non lactose fermenting non pathogenic bowel flora (B.coli) undergoes definite changes in the disease condition. While this alternation in the nature of bowel flora might be a mere concomittant to the disease condition, there is reason to believe that the B.coli actually turns pathogenic.

The balance of the bowel flora is disturbed in disease.

Similar changes are also observed in drug provings.

  • Paterson advocated specific recommendation on potency, dose and repetition of bowel nosodes.
  • He related each bowel nosode to a group of Homoeopathic remedies.
  • Bach found out that the non lactose fermenting gram -‘ve coli was closely associated with the symptoms collectively called Psora by Hahnemann.
  • Paterson believed that gram negative diplococci were directly related to the sycotic miasm.
  • He grouped and typed the flora by continuous experiment and observation. He was able to detect a definite relationship between certain drugs and certain types of bowel flora. When a particular drug was administered in potencies the bowel flora was altered in a particular way.
  • He divided the Morgan group of bacteria into 2 sub classes on bacteriological basis and thus created nosodes – Morgan pure & Morgan gaertner.
  • In1933 Paterson presented a paper on Sycotic co.
  • In 1950 he published summary of his accumulated experience.
  • After his death in 1954, his wife Elizabeth Paterson continued the research.


During case taking, great attention should be given to the past as well as the presenting complaint. Bowel nosodes are deep acting remedies so the case taking must cover the totality of symptoms. The nosode should be administered in the same manner as any Homoeopathic remedy, they should not be given empirically but only on Homoeopathic principles.

Paterson divided the case in to 2 groups

New case – when the patient has not taken Homoeopathic treatment.

Old case – a patient under Homoeopathic treatment but not responding well.


1. In a new case where a definite symptom picture points to a remedy, that remedy should be given, not the nosode.

2. In cases where the choice may be from a number of possible remedies, eg. Sulphur, Calcarea, Graphitis, and it is difficult to select a remedy from this, Morgan pure can be considered to cover the totality of symptoms by referring to the table of related remedies.


This is an individual who has had Homoeopathic treatment over a period of time and received a considerable number of remedies in various potencies. These are difficult cases, there is no available evidence from stool culture to give a clue to the group of remedies likely to be useful, or indications as to the phase in which the patient is at the moment.

In such cases, it should be remembered that the potentised remedy can alter the bowel flora. In old cases the remedy already given may have caused a positive phase of bowel flora, that is it changed the B.coli predominance to that of non lactose fermenting bacilli.

If the percentage of non lactose fermenting bacteria in the stool is greater than 50% the administration of bowel nosode is contraindicated, the nosode given at that time produces a negative phase with a corresponding period of vital depression in the patient. In such cases use a nosode in 6c potency in the first instance to avoid the chance of violent negative reaction.

The choice of the nosode for any case may be determined by a study of the clinical histories and noting down the remedies which have given the greatest, although not sustained effect. Tabulate this list of remedies and compare it with the nosode list and associated remedies and choose the nosode which has the greatest number within its group.


As usual in Homoeopathy, the more obvious the mental picture, the higher the potency, but lower the potency if marked pathological symptoms are present. But between these two extremes use the 30th potency–when there is a combination of acute and chronic state, for example, in chronic bronchopneumonia –

  • Proteus acts best in high potency
  • Gartner will not work in low potency

According to Paterson do not repeat a bowel nosode within three months, instead prescribe the homeopathically indicated similimum from the group of remedies (previously given) related to the bowel nosode.

After the administration of the suitable nosode, the curative process begins, the non lactose fermenting bacteria begin to mutate to other groups and ultimately disappear, these happenings occur simultaneously with the disappearance of the symptom, reappearance of the old symptoms and the efflorescence of the skin eruptions with ultimate clearing (Hering’s Law). This is associated with a marked increase in the vitality of the patient.

The bacilli change with the patient. This mutation of the non lactose fermenting bacteria back to normal coli has been demonstrated in the laboratory.

  • Hi
    Only just found your excellent article on the Bowel Nosodes.
    Which abbreviations do you use; as say Arg-n for Argentum nitricum etc.

  • article on bowel nosodes is very informative & useful,however if you publish a case of bowel nosode in h.pathy it will be of great help .

  • I am a 65 year old male and I went to see a homeopath for general health advice.

    I was prescribed Morgan Gaertner 200c 7 grams – 3 pills for 3 consecutive days

    Wait for 3 weeks

    Then take Lycopodium Clavatum 12c 7 grams – 2 pills a day for a month

    Please can someone tell me more about these items and the doses.

    Thank you


  • It would be wonderful if could put Elizabeth Paterson’s A Survey of Nosodes in their online library. It is a short pamphlet, I’ve been told, and is out of print. Thank you for your great efforts.

  • I have some question.
    In this book, “The Bowel Nosodes”, there are the following texts:

    *Read to the Rhodacienne Homoeopathic Society at the meeting of the International Homoeopathic League Council, August, 1949.

    Are this texts the quote of this book?
    If you know about this, can you tell me?

  • Hello
    Can you please tell me where can you purchase the Bowel Nosode B.Mutabile (Bach). I have never heard about it.

    i live in London UK and Helios Pharmacy does not have it and has not even heard about it?
    I too have not heard about this Bowel Nosode.
    Thank You
