Pseudo Psora and Its Evolution According to J.H. Allen

About J.H. Allen

John Henry Allen (died August 1, 1925) was a student of H.C. Allen and president of the International Hahnemannian Association (IHA) in 1900. He taught at the Hering Medical College, Chicago. His principal contributions to homeopathic philosophy are contained in two landmark works:

The Chronic Miasms: Psora and Pseudo-Psora (1908) - Volume I
The Chronic Miasms: Sycosis (1908) - Volume II

Allen is best remembered for introducing the concept of miasmatic diathesis - the tendency of a particular miasm to produce characteristic lesions - and for formally naming and defining Pseudo Psora as the Tubercular Miasm.

I. Background - The Miasm Concept

The word "miasm" originates from the Greek miasma, meaning a stain, pollution, defilement, or noxious atmosphere. Hahnemann originally identified three chronic miasms:

Psora - the mother of all chronic disease (itch diathesis)
Sycosis - the fig-wart disease (gonorrhoeal miasm)
Syphilis - the venereal destructive miasm

Hahnemann himself, near the end of his life, recognized a fourth miasm corresponding to the tubercular diathesis, which he called "pseudo-psora." He even prepared a nosode with this name. Boenninghausen had predicted that the original three miasms would be supplemented: "I do not wish to deny by any means that there may perhaps be, beside the three above-mentioned miasms, one or another additional miasm..."

It was J.H. Allen who gave pseudo psora its full systematic development, formal definition, and clinical elaboration.

II. Definition of Pseudo Psora (Tubercular Miasm)

According to Allen, Pseudo Psora is defined as a chronic miasm that arises from the combination and co-mingling of Psora and Syphilis in the same organism, resulting in a new, distinct, and more severe miasmatic state - the tubercular diathesis.

Allen's exact position (from The Chronic Miasms, Vol. I, p. 80, 134):

"When a suppression took place in an organism where two or more miasms were present, the internal conditions of the organism were magnified and intensified. When Psora and Syphilis are perfectly combined by hereditary transmission, the tubercular diathesis is the result of such a union."

Key points of his definition:

It is not a simple extension of Psora - it is qualitatively different
It is worse than psora by itself - more destructive and deeper acting
It arises when suppression occurs in an organism already carrying multiple miasms
When sycosis is added to the tubercular state, the condition acquires a malignant hue
The fundamental pathological expression is tissue destruction combined with inflammation - specifically: inflammation (from Psora) + lymphatic damage and tissue destruction (from Syphilis) = Tuberculosis

Allen classified tuberculosis under pseudo psora on the basis of his miasmatic diathesis concept, contrasting with Hahnemann, who attributed tuberculosis largely to Psora alone.

III. Evolution of the Concept of Pseudo Psora

Stage 1 - Hahnemann's Foundation (Early 19th Century)

Hahnemann described Psora as the oldest, most universal, and most pernicious chronic miasmatic disease. He noted that psora first manifested as:

A pruritus of some form
Followed by fine vesicular eruption (the itch eruption)

He established that psora could not appear primarily as eczema, psoriasis, etc. - those were secondary processes of psora, not primary manifestations. Near the end of his life, Hahnemann recognized the tubercular diathesis as potentially a distinct miasm and prepared the pseudo-psora nosode, but did not fully systematize it.

Stage 2 - Allen's Contribution - Formal Classification (1908)

Allen built upon Hahnemann's hint and gave pseudo psora its complete theoretical and clinical framework. His steps in the evolution of pseudo psora:

Step A - The Primacy of Psora as the Seed: Allen taught that psora is the "primary manifestation of primeval sin" - a moral and spiritual deficiency that manifests in the physical. Psora is the background soil upon which all other miasms operate. Without psora, the other miasms cannot take deep root.

Step B - Psora + Syphilis = Pseudo Psora: When Psora (the functional, deficiency-based miasm) combines with Syphilis (the destructive, ulcerative miasm), the organism enters a state where:

Inflammation is accompanied by tissue breakdown
The lymphatic system is progressively damaged
The lung parenchyma undergoes the characteristic tubercular changes (induration, caseation, cavitation)
Hereditary transmission locks this combined miasm into the constitution of future generations

Step C - Role of Suppression: Allen emphasized that suppression of skin eruptions or discharges in organisms already carrying latent miasms is the critical trigger for pseudo psora to emerge. When Psora's primary symptom (the itch eruption) is driven inward by wrong treatment:

The internal organs take up the burden
If syphilitic miasm is also present, the combined internal expression manifests as the tubercular disease process
The vital force, now deprived of its safety valve on the surface, turns the destructive process inward

Step D - Miasmatic Diathesis: Allen's concept of miasmatic diathesis - each miasm having a characteristic tissue tendency - placed pseudo psora in its own category:

Psoric diathesis: functional disturbances, no organic change, skin manifestations
Sycotic diathesis: overgrowth, inflammation of mucous membranes, condylomata
Syphilitic diathesis: bone lesions, ulcerations, destruction
Pseudo-Psoric (Tubercular) diathesis: chronic inflammation leading to induration, softening, abscess, caseation, cavitation - a blend of inflammation + destruction

Step E - Hereditary Transmission: Allen stressed that pseudo psora can be transmitted hereditarily. When parents carry the combined psoro-syphilitic constitution, children are born with the tubercular predisposition even without direct exposure to Koch's bacillus. The bacillus, when it does enter such a predisposed organism, finds fertile ground and proliferates - but the miasm (the susceptibility) predates the infection.

Stage 3 - Broader Context: Allen Among His Contemporaries

Hahnemann - Perceived miasms on the physical/clinical plane; attributed most chronic disease to psora.

Kent - Allen's contemporary; raised miasmatic theory to the philosophical/moral plane; also saw psora as spiritual deficiency. Allen agreed with Kent on the moral-philosophical basis.

Allen's unique contribution - Formally classified pseudo psora as a distinct fourth miasm with its own symptomatology, remedy repertory, nosode (Tuberculinum), and clinical expression. He was the first to systematically say: "This is not just heightened psora - it is a new miasmatic entity born from the union of psora and syphilis."

C.M. Boger (later) - Extended Allen's work; correlated miasms to pathological states; described disease as evolving dynamically: Psora → Sycosis → Tubercular → Syphilitic.

IV. Characteristics of Pseudo Psora (Tubercular Miasm) According to Allen

A. Mental/Mind Symptoms

According to Allen's The Chronic Miasms, Vol. I:

Thoughts:

Racing, wandering thoughts; difficulty concentrating
Persistent anxiety about health and the future
Morbid thoughts, fear of death, especially in the night

Anxiety:

Deep, causeless anxiety
Anxiety with restlessness - the patient cannot stay still mentally or physically
Anxiety driving the patient from place to place (changeability is a hallmark)

Fear:

Fear of the dark
Fear of disease (especially tuberculosis and hereditary ailments)
Fear that something terrible will happen

Mood and Memory:

Rapidly alternating moods - great elation followed by deep depression
Memory weakness with hypersensitivity to mental stimuli
Intense but short-lived enthusiasm; easily exhausted mentally

B. Physical/General Symptoms

Strong predisposition to Koch's disease (pulmonary tuberculosis), pleural effusion, Pott's disease, tubercular glands, and tubercular meningitis
Increased activity at all levels (mental and physical) followed by profound debility - the characteristic "burning the candle at both ends" pattern
Erraticity, periodicity, hyperdynamicity, changeability - no two attacks are the same; symptoms shift location and character
Superficial disturbances of circulation: bluish pallor, purple condition of extremities, chilblains, hypotension
Increased catabolism with decreased anabolism - poor assimilation, emaciation despite eating
Tardy convalescence and protracted recovery after acute illnesses
Easy suppuration with delayed healing; scars form but break down repeatedly
Healing through fibrosis of a puckered type, with frequent breakdown
Reduced resistance to tubercular infection following respiratory and other infections

C. Pathological Expression

The tubercular process expresses itself through:

Chronic inflammation → induration → softening → abscess formation → caseation
Cheesy, bloody discharges with musty/moldy odor
Sweetish expectoration
Lymphadenopathy progressing to suppuration

V. Pseudo Psora vs. Psora - Key Differences (Allen's View)

Feature	Psora	Pseudo Psora
Origin	Primary, ancient miasm	Combination of Psora + Syphilis
Nature	Deficiency, functional	Inflammatory + Destructive
Tissue change	No organic change initially	Induration, caseation, destruction
Skin	Itching, vesicular eruption	Pale, waxy, emaciated skin
Prognosis	Treatable if not suppressed	More serious; hereditary
Severity	Mother miasm	Worse than psora alone
Nosode	Psorinum	Tuberculinum
Disease example	Eczema (secondary), functional disorders	Pulmonary tuberculosis, TB glands, Pott's

VI. Nosode and Remedy

Allen associated Tuberculinum (prepared from tubercular tissue) as the primary nosode for pseudo psora. The remedy group associated with this miasm includes:

Tuberculinum (Koch's)
Phosphorus
Calcarea carbonica
Calcarea phosphorica
Stannum
Drosera
Pulsatilla (in certain aspects)

VII. Clinical Significance for Prescribing

Allen stated that the physician must:

Identify the basic/active miasm - look past presenting symptoms to the deeper constitutional state
Not interfere with the action of the well-selected anti-miasmatic remedy - avoid changing the prescription too quickly
Recognize the three errors of the physician: premature change of remedy, suppression of eruptions, and failure to identify the underlying miasm

When pseudo psora is the active miasm, the constitutional remedy must address the combined psoro-syphilitic background, and anti-tubercular nosode therapy (Tuberculinum in appropriate potency) forms part of the miasmatic treatment strategy.

VIII. Summary - Evolution in Brief

Period	Contributor	Contribution
Early 19th C	Hahnemann	Named pseudo psora; prepared nosode; hinted at fourth miasm
1888	Boenninghausen	Predicted additional miasms beyond three
Late 19th C	Kent	Philosophical extension of psora to moral/spiritual plane
1908	J.H. Allen	Full systematic definition of pseudo psora as Psora + Syphilis; tubercular miasm; miasmatic diathesis; complete symptomatology and repertory
Early 20th C	C.M. Boger	Dynamic evolution from Psora → Sycosis → Tubercular → Syphilitic
