If you are new to the study of Homoeopathic Philosophy, it is advisable to first understand the fundamental concepts related to the knowledge of drugs, because this forms the foundation of prescribing. In this article, we will clearly explain the difference between Drug, Medicine, and Remedy, and also discuss the curative power of medicines as explained in the Organon.
Knowledge of Drugs in Homeopathy
The introductory aphorisms of the Organon emphasize what every physician must know about drugs. According to Samuel Hahnemann, the primary characteristic of any drug is its capacity to alter the state of health. Only a substance capable of producing a change in a healthy individual can cure disease.
He famously concluded that:
“The disease-producing power of a medicine is the disease-curing power.”
This means that the very ability of a substance to produce symptoms in a healthy person becomes its power to cure similar symptoms in a sick individual.
Drug Proving on Humans
Hahnemann strongly opposed relying merely on speculation, theoretical reasoning, or experimentation on animals. Instead, he insisted that drugs must be:
- Proved on healthy human beings
- Proved on both sexes
- Proved across different age groups
Only then can we understand the true dynamic action of a drug.
He described:
- Knowledge of Drugs as a two-way path (drug → symptoms → cure)
- Knowledge of Miasms as a one-way path
1. Drug
Dr. H. A. Roberts defines a drug as:
“A drug is any material agent, in however attenuated form, the ingestion of which is capable of so disturbing the balance of the vital force that the functioning of one or more organs of the body is no longer carried out to the best of the whole.”
In simple words:
- A drug is any substance capable of altering the state of health.
- It may disturb the balance of the vital force.
- It is usually in its crude or unprepared form.
Sources of Drugs:
Drugs may be obtained from:
- Plant kingdom
- Animal kingdom
- Mineral kingdom
- Diseased products (Nosodes)
- Healthy secretions (Sarcodes)
- Natural forces
At this stage, a drug is simply a substance with potential power — its curative properties are not yet scientifically verified through proving.
2. Medicine
A medicine is a drug whose properties have been:
- Carefully proved on healthy human beings
- Recorded systematically
- Prepared according to definite pharmaceutical principles
In other words:
A drug becomes a medicine only after it has undergone proper proving and preparation.
Thus, a medicine is no longer just a crude substance. Its symptom-picture is known, its action is documented, and it is prepared in potentized form for therapeutic use.
3. Remedy
A remedy is the medicine that is specifically indicated for a particular patient.
According to §3 of the Organon, Hahnemann speaks about the “choice of the remedy” — meaning the medicine that is most similar to the totality of symptoms.
Homeopathically:
- A medicine becomes a remedy only when it matches the patient’s totality.
- It must be capable of curing in a rapid, gentle, and permanent manner.
- When one medicine covers the entire symptom-totality of a patient, it becomes the remedy for that patient.
So:
- Drug → A substance capable of altering health
- Medicine → A proved and prepared drug
- Remedy → The indicated medicine for an individual patient
