Testing on Healthy People
Remedies are tested on healthy volunteers to observe and record the symptoms they produce.
Founder of Homoeopathy
Dr. Samuel Hahnemann
10 April 1755 - 2 July 1843
Christian Friedrich Samuel Hahnemann was a physician, chemist, linguist, and tireless investigator who devoted his life to developing a gentler and more systematic approach to healing.
"In my lifetime I deserve no recognition for the beneficent truth which I have unselfishly propagated. What I have done for the world I have done from higher motives."
Dr. Samuel Hahnemann
A Life of Inquiry
Early Life and Medical Calling
Christian Friedrich Samuel Hahnemann was born in Meissen, Saxony, to Christian Gottfried Hahnemann, a painter, and Johanna Christiana Spiess. Although his family had limited means, his ability and determination enabled him to pursue higher studies. He studied medicine at Leipzig and continued his clinical education before receiving his medical degree in 1779.
Gifted in languages and chemistry, he supported his family through scientific writing and translation. His close study of medical literature, together with dissatisfaction with the harsh treatments then in common use, led him to suspend conventional practice and search for a more dependable law of cure.
Discovery
From the Cinchona Experiment to the Law of Similars
While translating a medical work in 1790, Hahnemann questioned the accepted explanation for cinchona bark's use in intermittent fever. He tested the substance on himself and observed a pattern of symptoms resembling the illness it was used to treat. Further experiments led him to formulate the principle similia similibus curentur - let like be treated by like.
He presented the principle publicly in 1796, establishing the starting point for the clinical method explained in the sections that follow.
The Law of Similars
Similia Similibus Curentur
“Let likes be cured by likes.”
Similia similibus curentur is the central principle of homoeopathy. In classical homoeopathic theory, a remedy is selected when its recorded symptom picture closely resembles the patient’s symptom picture.
Hahnemann contrasted this approach with contraria contrariis, the historical idea that opposites are treated by opposites.
Core Ideas
Matching Symptoms
A patient is given a small dose of the remedy whose known symptom picture most closely matches the individual case.
Triggering Healing
The small dose is intended, within homoeopathic theory, to stimulate the body's natural healing response.
Clinical Discipline
Three Errors to Avoid
Hahnemann’s teaching emphasises three cautions for the homoeopathic physician.
Distrusting the Minimum Dose
Do not assume that a correctly selected remedy is ineffective merely because the dose is small.
Careless Case-Taking
Avoid indifference, the pursuit of convenience, or pride that leads to disregard for the complete symptom picture.
Acting in Haste
Do not interrupt a remedy before it has had adequate time to complete its action.
Patient Research
Provings and the Materia Medica
Testing on the Healthy
He tested medicinal substances on himself and willing healthy participants, recording the symptoms they produced.
Many Sources
His investigations included substances derived from plants, minerals, animal sources, and chemical preparations.
Exact Observation
Changes in body and mind were documented carefully and compared with the complete symptom picture of the patient.
Minimum Dose
He refined methods of preparation and dosage while seeking effective treatment with the least possible medicinal intervention.
Materia Medica Pura
Beginning in 1811, his collected observations were published as a foundational record of remedy pictures.
Continual Revision
He repeatedly reviewed his conclusions in the light of experience and revised his writings throughout his life.
Foundational Works
Organon and Chronic Diseases
Organon of Medicine
The Organon of Medicine is Hahnemann’s central exposition of homoeopathic principles, clinical observation, remedy selection, and the physician’s duty.
The Chronic Diseases
First published in 1828, The Chronic Diseases presented his later inquiry into persistent disease and chronic miasms.
Discipline in Practice
The Physician's Responsibility
Historical accounts portray Hahnemann as exacting, self-reliant, and devoted to the care of the sick. He insisted on earnest case-taking, freedom from prejudice, patient observation, and enough time for a correctly selected remedy to act. He warned against careless prescribing, unnecessary repetition and the indiscriminate mixing of different medical methods.
His guidance also considered food, habits and the conditions of daily life, especially in chronic illness. The physician, in his view, needed knowledge, moral courage, compassion and an untiring commitment to truth.
He advised identifying dietary, environmental and habitual influences that might obstruct treatment, while adapting guidance to the individual case. These historical directions belong within qualified clinical judgment and should not replace necessary medical care.
Method in Practice
Understanding the Complete Case
Hahnemann taught that the physician should understand the patient's complete symptom picture and select the remedy whose known picture most closely resembles it.
The Complete Symptom Picture
Collected symptoms are organised and evaluated according to their individual character and clinical importance.
- General symptoms - features affecting the person as a whole
- Mental symptoms - emotional and mental disposition
- Modalities - factors that improve or aggravate symptoms
- Peculiar symptoms - striking, unusual and characteristic features
- Causation - the circumstances or events associated with onset
One Remedy, One Dose
The method calls for a single, carefully selected remedy at a defined potency.
Hahnemann opposed giving two remedies simultaneously. His method calls for observing the action of the selected remedy and repeating or changing it only when the evolving symptom picture justifies that decision.
Observe Before Repeating
A dose should be allowed sufficient time to act according to the patient's condition and response. Hasty repetition, frequent changes, or intervening remedies may make the case more difficult to interpret.
Similar and Dissimilar Disease
In Hahnemann’s theory, a stronger similar disease state could permanently displace a weaker one, while a stronger dissimilar state might only suspend the weaker state temporarily. Remedy selection therefore follows the symptom totality present at the time of examination.

"On my honour, I swear that I shall practise the teachings of homoeopathy, perform my duty, render justice to my patients, and help the sick whoever comes to me for treatment. May I have the strength for fulfilment of my mission."
A guiding pledge for every homoeopathic physician
An Enduring Legacy
Hahnemann's life joined intellectual courage with sustained service. He gave up a successful conventional practice, tested his ideas on himself and through sustained observation, and spent decades refining a system intended to alleviate suffering. His writings continue to be studied by homoeopathic physicians and students throughout the world.
