The authors discuss the concept of susceptibility in homeopathy.

What is Susceptibility?


To establish what susceptibility is, it is wise to look at conventional definitions as well as the homeopathic perspective. We must include the views of founding fathers Samuel Hahnemann and J.T. Kent; after-all they laid the groundwork of homeopathic philosophy to which we still adhere today.  The Oxford Dictionary definition of susceptibility is “the state or fact of being likely or liable to be influenced or harmed by a particular thing”.  Allopaths are more likely to focus on external factors that make us susceptible to illness such as infectious diseases, germs, allergens, living conditions or pathogenic agents and would say that we lack immunity or resistance and thus are more likely to become attacked with a sickness – hence conventional medicines focus on healing with opposites.  Whilst taking this stance into account, homeopaths also will focus on internal factors which make us susceptible to certain illnesses. Simply put, susceptibility is the reaction of the person to external and internal influences. This predisposition can make us more inclined to becoming ill.


Hahnemann said our vital force will “express itself through disease symptoms in the organism” – Aphorism 11 p11 Organon Unfolded. He talked extensively on the subject of susceptibility and provided the view that our miasmatic taint, constitution, physical and psychological makeup will also contribute to our predisposition to certain illnesses.  Aphorism 31 p15 of The Organon Unfolded states: “Morbific disease agents do not derange health unconditionally.  We fall ill only when our organism is susceptible. They do not produce disease in everyone at all times.” In other words to be susceptible to a certain disease our individual vital force must be disposed to it on a physical, mental and emotional level. If our vital force is not susceptible to it, there will be no disease. In Aphorisms 32 and 33 Hahnemann also points out that Allopathic medicine will affect all people at all times, whereas natural disease will not affect all people at all times i.e. “People are therefore unconditionally susceptible to medicinal forces.  Natural diseases affect people conditionally” – Aphorism 33 The Organon Unfolded p15. Even Hippocrates (c460 BC – c370 BC) acknowledged that genetics or what Hahnemann called ‘Miasma’ had an influence on our susceptibility to illness in his tome ‘Sacred Diseases’. He said that diseases found in a mother and father are often found in their children. However it should be noted that even siblings within a family can be very different and have different susceptibilities taken from either the maternal or paternal side or both.


Kent expanded on Hahnemann’s writings on the subject:

 “Because of these varying degrees of susceptibility some are protected from disease cause and some are made sick; the one who is made sick is susceptible to the disease cause in accordance with the plane he is in and the degree of attenuation that happens to be present at the time of contagion” – Lectures on Homeopathic Philosophy p121. Here he is saying that we all have different degrees of susceptibility and that some people will become ill when exposed to certain internal or external factors and others will not. He also states that when we are exposed to natural disease and recover from it, we will not be susceptible to that same disease.  For example if we get a normal childhood illness such as chicken pox once, we recover and will then no longer have susceptibility to it. Kent continued “When a violent epidemic is raging we all know that, although the number of victims is large, they are few compared to those who go through the epidemic unscathed…we suppose…that a large number of the immune have escaped because they were usually strong and vigorous…but we find among those that have escaped the epidemic are a large number of persons who are anything but strong…the reason is that they have a sickness that is impossible for the epidemic to suppress…if the chronic disease is stronger than the epidemic disease…it cannot be suppressed” – Lectures on Homeopathic Philosophy p127-128. Here Kent is saying that the reason these people lack  susceptibility to the epidemic disease is because the disease with which they are suffering is dissimilar to the epidemic and stronger.



What make us susceptible?

Susceptibility in a person can be inherited from parents. It depends on the miasmatic background of both parents. It is also influenced by the mental condition and circumstances during the production of sperm and ovum. An interaction of all these determines the miasmatic background of the individual.

Early and late environmental factors may also influence the development of susceptibility. Early environmental factors involve conditions pertaining to intra-uterine life. Any influence or indulgence during the gestational period may affect the development of susceptibility of the individual such as worries, diseases, tension, smoking, alcoholism, or malnutrition.

Late environmental factors also affect the development of susceptibility. These involve the influence during childhood and adulthood. H.A. Roberts wrote “Everything that has life is more or less influenced by circumstances and environment.” We see very frequently the susceptibility to climatic conditions, as well as all other phases of environment. One person will thrive in a rigorous climate where another will become seriously ill; one will thrive in dampness to which another would succumb. Altitude affects some individuals kindly and some adversely. The seashore improves one man’s condition while it makes another man ill. The power of assimilation and nutrition is one of the phases of susceptibility. One easily assimilates a certain kind of food while another finds the same food indigestible.

Human beings are susceptible to infection and contagion in varying degrees. One man will become infected in contact with diseased individuals while another will experience no ill effects. One person is made ill by noxious plants, while another man can handle them with impunity.

Thus both genetic and environmental factors determine the susceptibility of the individual. This is why pathogenic agents do not affect every person nor the same person all of the time. The patient must be sufficiently susceptible according to the time and circumstances. Susceptibility varies in degree in different patients, and at different times in the same patient.

Before deciding to train as a homeopath Helen worked in the education and fundraising sectors. She is now a full time mum to two boys, and looks forward to graduating this summer so she can put all of her homeopathic training into practice.

My mum is responsible for my love of homeopathy. She always had a kit with her, and growing up I thought homeopathy was the norm. For every ailment or injury her box of remedies would come out and "fix" us. From about 17 O wanted to become a homeopath. Four children and a couple of businesses later, I decided I had to study and become a homepath. Homeopathy has transformed my life, my family’s life and in the process of practicing as a student has changed lives of my patients. Homepathy is part of me and always will be.

Paloma Vazquez Santiago

My first contact with homeopathy took place while working as a pharmacist in Madrid. Most of the customers who used homeopathy were quite happy about their results so I was intrigued by it. Four years ago I had the chance to study it deeply. As a pharmacist I was quite disappointed about the side effects of medication. Being aware of another way to understand health and disease was an enormous impact on me. Homeopathy is a blessing in my life.

    Excelente el informe. Luego de tantos años de adhesión a la homeopatía me he cruzado con esta explicación que me permite conectar conocimientos que tenía desconectados. Mil Gracias!!! Se lo estoy enviando a mis hijos, tratados exclusivamente por médicos homeópatas. El Prof. Dr Carlos Eduardo Vila y el Prof. Dr Florencio Escardó. con quienes estoy en deuda por los siglos de los siglos. Reciban mis cálidos saludos,

      Gracias por tu comentario y por leer el artículo. la idea era precisamente esa, conectar parte de la filosofía homeopática con un caso práctico.

    Yes! Why no description of remedies?

      Dear doctors,
      The aim of the article was to describe susceptibility and link it to a practical case. The treatment of the boy was long ( more than 3 years) to get him back to a “normal” spectrum. Of course, he is still in treatment with homeopathy.
      All I can share with you is the first remedy: Nitric ac. Although it is not a specific remedy for authism, his behaviour and the totality of his symptoms matched with the remedy picture. He was in treatment with nitric ac for 6 months.
      thanks for reading the article and for your coment.

    Thanks for a nice case. It is a beautiful depiction of the history and problems of the patient. However, lack of the treatment part would have been immensely useful adding full value to the case and homeopathy.
