In homoeopathy, understanding the cause of disease is fundamental to effective treatment. According to Aphorisms 5 and 7 of the Organon of Medicine, a physician must not only observe the symptoms but also investigate the underlying causes that have led to the diseased state.
Hahnemann clearly states that the “portrait of disease” is the true and only conceivable representation of the total collection of perceptible signs and symptoms — including changes in both body and mind. However, to fully comprehend this portrait, the physician must carefully analyze the causes behind it.
He categorizes the causes of disease into three main types:
- Exciting Cause (Aphorism 5)
- Fundamental Cause (Aphorism 5)
- Maintaining Cause (Causa Occasionalis) (Aphorism 7)
Let us understand each in detail.
1. Exciting Cause (Aphorism 5)
The exciting cause is the most probable precipitating factor responsible for initiating an acute disease. It is the event or circumstance that triggers susceptibility and brings the disease into active manifestation.
Importance in Acute Diseases
In acute conditions, understanding the exciting cause is essential because it helps in forming the totality of symptoms. It answers the question:
“What triggered the illness?”
When treating acute cases, the physician must identify the factor that “excited” the susceptibility of the patient.
Types of Acute Diseases and Their Exciting Causes
(As discussed in Aphorism 73)
- Individual Acute Diseases
These arise from personal exposure to harmful influences such as:- Excess or deficiency of food
- Physical strain
- Chills or overheating
- Suppressed discharges
- Mental shock or emotional stress
- Acute anxiety or grief
- Sporadic Diseases
These occur due to environmental influences such as:- Meteoric changes
- Telluric influences affecting multiple individuals
- Epidemic Diseases
These arise due to:- War and calamities
- Floods or famine
- Peculiar acute miasms (recurrent or non-recurrent)
Thus, the exciting cause is primarily important in understanding and managing acute diseases.
2. Fundamental Cause (Aphorism 5)
The fundamental cause is the deep-seated, primary, and underlying cause responsible for the persistence and development of chronic disease.
While exciting causes may initiate acute illnesses, they cannot explain why a disease becomes chronic or continues for years. Chronic diseases require deeper investigation.
Importance in Chronic Diseases
The fundamental cause explains:
- Why the disease persists
- Why it develops gradually
- Why it worsens over time
To identify it, the physician must evaluate:
- Physical constitution
- Moral and intellectual character
- Occupation
- Mode of living and habits
- Social and domestic relationships
- Age
- Sexual functions
A thorough history of the patient is essential to uncover the true nature of chronic disease.
Why Exciting Cause Alone is Insufficient
A trivial exciting factor cannot produce a long-standing chronic disease. Therefore, to understand chronicity, one must investigate the whole history of the disease, not merely the recent trigger.
Types of Chronic Diseases According to Hahnemann
Hahnemann classified chronic diseases into three categories:
1. Artificial Chronic Diseases
These arise due to prolonged use of harmful medications, especially suppressive treatments.
2. Pseudo-Chronic Diseases
These result from:
- Unhealthy lifestyle
- Poor hygiene
- Nutritional deficiencies
- Lack of proper living conditions
Such conditions may appear chronic but are often reversible with correction of lifestyle.
3. True Chronic Diseases
These are caused by chronic miasms:
- Psora
- Sycosis
- Syphilis
These miasms represent deep-rooted dynamic disturbances requiring anti-miasmatic treatment.
3. Maintaining Cause (Causa Occasionalis) – Aphorism 7
Although not elaborated extensively in the above content, Aphorism 7 introduces the concept of the maintaining cause.
A maintaining cause is any factor that:
- Keeps the disease active
- Prevents recovery
- Continues to disturb the vital force
Examples include:
- Continuous exposure to allergens
- Ongoing mental stress
- Poor hygiene
- Addictions
- Toxic work environment
Removal of the maintaining cause is essential before expecting complete cure.
In homoeopathy, treatment is not based merely on diagnosing the disease label but on understanding its cause and totality.
- The Exciting Cause helps us manage acute diseases.
- The Fundamental Cause explains chronicity and directs anti-miasmatic treatment.
- The Maintaining Cause must be removed to ensure complete cure.
As emphasized by Samuel Hahnemann, a physician must carefully investigate not just symptoms but the complete background of the patient — physical, mental, social, and constitutional — to arrive at true healing.
Understanding these causes forms the cornerstone of rational homoeopathic prescribing and aligns with the principles laid down in the Organon of Medicine.
