Dr. Francisco Xavier Eizayaga is an Argentine homeopath whose contributions to homeopathy rapidly achieved international recognition. He was born on January 23, 1923, in the province of Santa Fe, Argentina.
Francisco Eizayaga studied medicine at the Medical University of Buenos Aires. He worked as an urologist with Professor A. Astraldi in the Hospital de Clinicas, in the Hospital Ramos Mejia and in the Urology Department of the Hospital Municipal de Vicente Lopez, province of Buenos Aires.
From 1949 to 1950 he studied homeopathy at the Asociacion Medica Homeopatica Argentina (AMHA). There he became an associate professor in 1954, and a full professor in 1964. He was the president of the Asociacion Medica Homeopatica Argentina for 14 years.
Dr.Francisco Eizayaga worked as a classical homeopath in his practice since 1952.
In 1988 he established the Instituto Superior de Homeopatia Clinica de la Fundacion HOMEOS in Buenos Aires. Its aim was teaching and investigating homeopathy, as well as its expanding it to support medical care through homeopathy clinics, and training courses for physicians.
From 1951 he regularly taught clinical homeopathy in Argentina, primarily at the AMHA, and since 1989 at the Instituto Superior de Homeopatia Clinica de la Fundacion HOMEOS, Buenos Aires. He also lectured on homeopathy worldwide, including Brazil, USA, Mexico, Colombia, Uruguay, Venezuela, Chile, UK, Spain and Canada. He taught the first complete homeopathy course in San Pablo, Brazil, from 1976-1977, and gave more than 350 seminars.
Francisco Eizayaga was married to Berta Amalia Klein, and they had eight children and nineteen grandchildren. Three of his children also became homeopathic physicians. The family was united by a strong affection and they lived by the highest principles. His son Dr. Jose Enrique Eizayaga is a well known homeopath who also graduated as a homeopathic physician at the Asociacion Medica Homeopatica Argentina (AMHA) and lectures at the Universidad Maimonides in Buenos Aires, Argentina.
Francisco Eizayaga passed away on June 25, 2001, in Olivos, province of Buenos Aires, Argentina.

- Enfermedades agudas febriles (Acute febrile diseases)
His books, Treatise on Homeopathic Medicine and Kent’s Modern Repertory are included in the curriculum in almost every Spanish Homeopathy School in the world.
Dr.Francisco Xavier Eizayaga is considered internationally as one of the great masters of homeopathy and known as a homeopathic physician with absolute moral integrity and an exceptional dedication to teaching. He conveyed optimism and confidence about homeopathy, based on his results in clinical practice. He passed on his knowledge unconditionally to new generations of young disciples and inspired many homeopaths on their path to learning. One of them is Dr. Eugenio Candegabe, another famous Argentine homeopath. Francisco put him in contact with homeopathy for the first time when they were working at the External Consultation Services of the Department of Urology at the Hospital de Vicente Lopez. Eugenio Candegabe appreciated Francisco Eizayaga as a physician with a passion for his profession, and secure in his knowledge of prescribing. Among Eizayaga’s great contributions to homeopathy, Dr. Candegabe points to his enormous capacity for teaching, his special skills as a practitioner, and his book, Kent’s Modern Repertory, which was the first translation of Kent’s book into the Spanish language. Many other homeopaths report having the good fortune to meet Francisco Eizayaga and called him a “Master Par Excellence”.
Francisco Eizayaga’s Layer Approach
Eizayaga opines that the different evolutionary states of the disease and their degrees of seriousness require different clinical and therapeutic criteria. Treating different kinds of similitude’s requires knowledge of the pathological process and the evolutionary stage, as well as an exact clinical and pathological diagnosis of the disease, and distinguishing between the symptoms of the patient and the symptoms of the disease.
He points out that whereas allopathy only focuses on the lesional disease, and has no answer for the preceding stages, the therapeutic possibilities of homeopathy also include the preceding stages, as well as severe infectious, lesional, and tumorous diseases.
Francisco Eizayaga’s model is based on the following assumptions:
- Disease is an expression of the disturbed vital force. It always progresses from functional disturbances in the individual’s psyche and the general functions, to structural changes in local parts, and from slight to deep pathological manifestations. This is expressed in the following sequence:
a) Illness in its first stage is only emotional-affective and easy to cure by returning the lost equilibrium. Within this stage ailments of the emotional and affective sphere, sensorium, coenesthetic sensations, and central nervous system occur.
b) In the second stage the illness also involves the general state of being. General symptoms which refer to the totality of the organism, indicate the involvement of the whole economy and the homeostatic alteration.
c) In the third stage local symptoms appear, due to the affection of organs and organ systems. Organic manifestations in acute as well as chronic diseases appear according to the known sequence of pathological stages: irritation, inflammation and dysfunction, followed by reversible and irreversible organic or tissue lesions, indicating a growing severity in the vital imbalance. The illness may have emotional-affective, general, local, only general, or only local manifestations.
2. Based on the different evolutionary stages of the disease progress, Eizayaga distinguished between different “layers”:
a) Morbid trends and predispositions of the constitution, no pathology
b) Morbid trends expressed in the miasmatic terrain, no pathology
c) The Fundamental disease with psychosomatic and general symptoms. This relates to the first and second stage of the disease.
d) The Lesional disease with local pathology or clinical entity, which is seen as the “disease” itself. This relates to the third stage of the disease.
3. Eizayaga classified diseases from the clinical, anatomo-pathological viewpoint as follows:
- Functional disturbances: These comprise the first and second stage of the disease, i.e. the fundamental disease.
- Lesional diseases: The third stage of the disease.
4. He clearly differentiated between the treatment of the patient and the treatment of the disease, based on distinguishing between “the patient’s symptoms which precede the disease from the symptoms of the disease itself”. The treatment of the constitution and the fundamental disease comprises the treatment of the patient. The treatment of the lesional disease constitutes the treatment of the actual disease.
5. Based on this concept he suggested treating the patient in “layers” according to their state: Treatment of the constitution, the miasmatic terrain, the fundamental disease, and the lesional disease. Treatment has to begin with the outmost layer, progressing deeper inwards with each prescription. It has to proceed in the following sequence:
- Lesional disease: Treatment of the disease with the lesional, similar remedy.
- Fundamental disease: Treatment of the patient with the fundamental remedy, the simillimum, to restore the psychosomatic balance.
- Morbid terrain: Miasmatic treatment with the corresponding nosode(s) to eliminate morbid trends.
- Constitution: Constitutional treatment with the constitutional remedy to prevent further diseases.
Eizayaga distinguished between the genotypical constitutional and phenotypical constitutional diagnosis. The genotypical constitution refers to the “way of being” of a person and their normal individual features. We are born with hereditary genetic and constitutional characteristics and certain organic structures and functions of the organs, which depend on the genotype. These may move and oscillate within a certain range, but are considered to be normal and not pathological.
Characterological features are not real symptoms, “but just psychic characteristics which pre-exist in the individual before any pathogenesis and must not be considered abnormal either, even though they are taken into consideration for the prescription“. Certain characteristics and symptoms help us in prescribing the constitutional remedy because they are the differentiating, individualizing factor between patients. Even if they are not pathological symptoms in themselves, they help us to individualize the patient and remedy. Eizayaga opines that, if characterological features are found in the materia medica and repertory, besides the really pathogenetic symptoms, “this is due to the proven fact that certain individuals who possess the same psychic characteristics of certain medicines are especially stimulated by them“.
The constitutional remedy is prescribed to prevent the development of diseases and future ailments that the patient may develop otherwise. It does not cure anything. It is to prescribe once the lesional and fundamental diseases have been cured and the morbid terrain has been cleared.
Eizayaga identified four normal genetic constitutions: Sulphur, Calcarea carbonica, Calcarea phosphorica, and Calcarea fluorica.
The phenotypical constitutional diagnosis relates to the fundamental disease.
Miasms constitute the morbid terrain and determine the diathetic pathological trends of all individuals. “All human constitutions have a morbid predisposition implicit in them or, in other words, they are inclined to certain illnesses, depending to a great extent on their diathesis or active miasm.”
Morbid tendencies develop slowly and according to a chronology which practically repeats itself in the majority of cases. Francisco Eizayaga identified five miasms: Psora, Sycosis, Syphilis, Tubercular and the Cancer Miasm.
When writing on What must be cured in diseases Eizayaga clearly suggests that miasmatic treatment requires prescribing the diathetic or miasmatic nosode or nosodes to eliminate the individual’s morbid trend. Nosodes must be customarily administered in high potencies.
In another chapter of his book Eizayaga does not limit miasmatic treatment to the application of nosodes, but points out the anti-miasmatic properties of other remedies and their indications: The morbid process which arises due to the active miasm may prevent the indicated remedy from acting efficaciously, and requires application of the remedy or the nosode that corresponds to this miasm. Each miasm has its typical remedies like Sulphur and Psorinum for Psora, Thuja, Medorrhinum and Nitricum acidum for Sycosis, and Mercurius, Aurum and Syphilinum for Syphilis . Regarding miasmatic treatment he states:
“Ever since homeopathy has existed, right from Hahnemann up to today including the most traditional authors like Kent, miasmatic treatment has been achieved by employing the Law of Similitude through the Materia Medica and the repertory.”
He also admits that acute exacerbations of the chronic miasm are effectively prevented with constitutional and fundamental treatment.
The phenotypical constitutional diagnosis relates to the fundamental disease and emerges from the pathological sufferings. It comprises the psychophysical constitution and is not measured by the patient’s skeleton, nor by the circulating humors or the predominant metabolic type. It is “measured by the dynamic dysequilibrium of a subject expressed in psychical, general and local symptoms liberated by traumatic circumstances in a predisposed, susceptible person“. This constitutes the fundamental disease.
The functional disturbances occurring within this fundamental layer, may manifest on the psychic and sensitive, general or local organic level. As there is no cell destruction, but only a temporary transformation of cell structure, the pathological stages are limited to irritation, inflammation and dysfunction, with the possibility of “restitutio ad integrum”.
The psychosomatic symptoms are considered to be the symptoms of the patient and precede the symptoms of the disease itself. “They are revealing a pathological alteration of the phenotypical constitution which must be treated with the so-called fundamental remedy or simillimum with which we shall not only cause the disturbed individual to recover but also we will prevent the future evolution and organic localization of the progressing disease“.
The prescription of the fundamental remedy, which is called the simillimum, is based on the patient’s characteristic, psychic modalities, general and local symptoms. “In chronic patients, not only symptoms of the current illness should be taken into account, but rather, and most principally, the chronic and pathobiographic symptoms of the patient, in order to find the profound temperamental and constitutional motivations that have lead to his present state.“ “The top hierarchical symptoms to base the prescription on are always those extracted from the pathobiographical history, i.e., the phenotypical constitutional symptoms, those which express the individual psychophysical temperament of the patient when faced with his personal, familial and social reality.”
In functional disturbances as occurring within the fundamental layer, medium, high or very high potencies can be prescribed.
Within this stage the patient develops lesional pathology due to structural and microchemical changes in the cell. The localization of the pathological process provides us with local symptoms, i.e. particular symptoms localized in organs or systems, which are common or pathognomonic. The case is curable if superficial organs are affected, even if some superficial lesion may persist. The affection of a vital organ transforms the disease into an incurable case.
Lesional diseases are classified as:
- 1. Lesional reversible diseases
- 2. Lesional irreversible diseases
- In lesional reversible diseases the structural alterations that occur on account of functional or organic disturbances, can be cured with “restitutio ad integrum” and complete functional recovery. They are localized when comprising a localized area, or diffuse, when comprising a whole organ or system. They may manifest as lesional reversible mental, general or local disease.
- In lesional irreversible diseases, cellular changes cannot be restored ad integrum, because cells have reached a no-return point in the pathological process. One can distinguish between focal and diffuse irreversible lesions. They are localized or focal when comprising a localized area, or diffuse, when comprising a whole organ or system.
Francisco Eizayaga differentiates irreversible diseases according to their curability and gives the following explanation: “Focal irreversible lesions may be cured clinically by means of scarring, but they cannot be cured histologically because there is no “restitutio ad integrum”. Irreversible diffuse lesions, instead, comprise the whole organ and are really incurable, as the scarring of the whole lesion would mean the total annulment of the organ and, therefore, of its function“.
That is, lesional diseases can be grouped according to their curability into:
a) Reversible and curable diseases.
b) Irreversible but semi-curable diseases. This occurs in focal lesions that cannot be cured histologically but only clinically, always provided function can be restored or compensated.
c) Irreversible and really incurable diseases. If the irreversible lesion comprises a whole vital organ only palliation will be possible. If however it comprises a non-vital organ, it will be without general repercussion.
In all these cases homeopathy offers an excellent option for treatment.
Local lesions are chronologically the last to appear and are called the “actual disease” of the individual. “The morbid localizations indicate “the illness the patient has” “, and from thence the treatment must begin. In lesional diseases in which there is a clinical entity, treatment must be directed first at this organic aspect of the disease, “because it is the most serious and the one which must be aided by us first. The prescription must be based on modalized local symptoms, placing the strictly pathological or organic symptoms in a pre-eminent position “.
“It is true that when a clinical disease level and a constitutional or miasmatic fundamental condition coexist, in said case the disease must be treated first and then the patient.”
F.Eizayaga, Treatise on Homoeopathic Medicine, p.292
To choose the remedy only the actual symptoms with their characteristic modalities have to be considered, leading to the prescription of the “similar” remedy. That is, the remedy must cover the pathological symptomatology, yet it must be individualized and modalities considered. Eizayaga emphasized that the common symptoms do not interest us as such, but that the modified symptoms with concomitants and alternating and subjective symptoms, and the rare or peculiar, characteristic symptoms are important for the homeopath. Only these give the strictly individual symptoms. He advised us to make use of all symptoms of the local disease including its modalities and concomitants, and those psychiatric symptoms that “appeared or were exacerbated right from the beginning of the disease and that are not chronic symptoms of the patient which preceded this disease“.
Eizayaga also suggests investigating the fundamental remedy: “The chronic patient, who is to be found in the background of the “actual illness“, presents mental and general symptoms with their corresponding modalities of aggravation and amelioration and his desires and aversions for food. In these symptoms may be found the image of a “patient who suffers the illness“, reinforced and completed by the image that the personal history gives.”
The therapeutic ideal is when the fundamental remedy (simillimum) also covers the symptoms of the clinical entity, i.e. agrees with the lesional remedy (similar), as this gives more certainty regarding success. In this case the simillimum is to be prescribed.
Eizayaga’s comments on how to proceed when the lesional and fundamental remedy do not agree, are somewhat contradictory.
He advises, that in “cases in which there is a clinical entity… what must draw our attention first is this organic aspect of the disease, because it is the most serious and the one which must be aided by us first.”  The prescribed remedy has to cover the active pathology by all means. Therefore, he concludes that when the investigation of the fundamental remedy reveals it does not agree with the lesional remedy, treatment should be started with the lesional remedy. Referring to the seriousness of pathology, he advises that the similar remedy for the disease should be prescribed in severe and organic cases, if this differs from the patient’s simillimum. He also advises, that in incurable cases it is “not adequate to use the simillimum remedy, but the one which covers the present sufferings“.
However, in another chapter of his book he writes that the patient’s individuality will always be present and that no strict rule can be given as to whether the lesional remedy is to be taken before the fundamental remedy, simultaneously with it or after it. Each case is to be solve individually.
Eizayaga emphasizes the therapeutic limitation of the similar remedy, which merely aims at curing the “present disease”. Only the simillimum treats the individual as a person, hence the lesional remedy is to be followed by the patient’s fundamental remedy, and then by miasmatic and genotypical constitutional treatment.
Therapeutic hints from Eizayaga
Francisco Eizayaga writes that although the patient is sensitive to any potency of the indicated remedy, there are degrees of efficacy of each potency. The similitude may correspond to low, medium and high potencies, according to the susceptibility of each patient. Certain cases however, may require a particular potency for cure, and there are special cases where the patient will only react to certain potencies. The homeopath will only tap homeopathy’s full therapeutic potential if low and high potencies are used.
Eizayaga writes that any curable disease can be treated with remedies at any potencies. These include functional disturbances, lesional reversible diseases, and semi-curable lesional irreversible diseases with compensative function. Also in the treatment of curable lesions, reversible or not, medium, high or very high potencies can be prescribed.
It is therapeutically important to consider that higher potencies, diluted beyond the Avogadro’s number, do not act on diffuse or incurable irreversible lesions. Therefore, incurable focal diseases with a non-compensatory function and incurable diffuse lesional diseases must be treated with remedies applied in mother tinctures or low potencies, as only these are appropriate to their lesional similarity.
Eizayaga distinguished lesional irreversible diseases according to their curability with dynamized medicines as follows:
- A focal lesion with compensatory function is curable with a dynamized medicine.
- A focal lesion with non-compensatory function is incurable with dynamized medicine.
- A diffuse lesion with destruction of a whole non-vital organ is incurable but without general repercussion.
- A diffuse lesion, comprising a whole vital organ is incurable with a dynamized medicine.
He mentions, that it is not always possible to determine the curability of a pathological process, so that the homeopath should try treatment with dynamized medicines and will often cure what was not considered to be curable.
Acute diseases are to be treated with the acute intercurrent remedy, considering first the “pathological symptoms as the ones of greatest repertorial value for the prescription“. Eizayaga states that the remedy has to cover the most serious organic pathology and recent ailments. Psychic and causative symptoms only have to be considered secondly.
