As public interest in homeopathy continues to increase, so does the responsibility to ensure the public understands what homeopathy truly is. Too often, the name “homeopathy” is used to describe approaches that bear little resemblance to the system of medicine developed by Samuel Hahnemann. This not only creates confusion but also places clients at risk of making healthcare decisions based on inaccurate representations of homeopathy practice.
Through our affiliated teaching and professional clinics, we collectively oversee the care of more than 500 clients per year. We know homeopathy is incredibly gentle and effective when used appropriately – after all we have over 200 years of clinical evidence to support this.
However, we are seeing a growing number of individuals who have previously undergone treatments represented as “homeopathy” that do not adhere to the foundational principles of authentic homeopathy practice. In an alarming number of these cases, we have documented evidence that clients experience a worsening of symptoms and a deterioration of vitality following those interventions.
These experiences underscore why it is essential to distinguish authentic homeopathy from practices that simply borrow its name. Protecting the integrity of homeopathy is not merely a matter of professional identity – it is necessary for public trust and confidence.
The American Institute of Homeopathy Consensus Definition of Homeopathy is an important step toward restoring clarity and protecting both the public and the profession. The Institute for the Advancement of Homeopathy is proud to adopt this Consensus Definition in support of effective, ethical, and authentic homeopathic practice.
Homeopathy’s remarkable record of more than 200 years of clinical experience and positive outcomes depends upon the faithful application of its foundational principles. We encourage practitioners, educators, organizations, and advocates who share these principles to publicly adopt and promote the Consensus Definition. By speaking with one voice about what constitutes authentic homeopathy, we can strengthen public understanding, promote greater confidence in homeopathy care, and preserve the principles that have guided the profession for more than two centuries.
The AIH Consensus Definition of Homeopathy
DEFINITION OF HOMEOPATHY
HomeopathyÂč is a system of medicine based on the reproducible observation that disease may be treated by a substance that produces similar effects in healthy individuals.ÂČ This observation, known as the law of similarsÂł (Similia Similibus Curantur), was developed into a therapeutic system by Samuel Hahnemann.âŽ
FOUNDATIONAL PRINCIPLES OF HOMEOPATHIC PRACTICE
Homeopathy is practiced in strict accordance with the method described by Hahnemann in the Organon of Medicine, Materia Medica Pura, Chronic Diseases, and Lesser Writings. True homeopathic practice adheres to the following fundamental principles:
1. LAW OF SIMILARS
A homeopath prescribes a medicine that has been shown through carefully conducted trials (provings) to produce effects similar to those of the patientâs illness: the more similar, the more effective the result.â” The medicine is selected based on the totality of characteristic symptoms of the patient, not on disease diagnosis alone.
2. SINGLE REMEDY
To secure the best practical results, medicine must be administered singly. Only one medicine is prescribed at a time, never mixtures of multiple medications or combinations. This principle allows clear observation of the medicineâs action and the patientâs response.
3. OPTIMAL POSOLOGY
A single medicine is prescribed for its dynamic property in optimal posology, meaning the correct potency (degree of dilution and succussion), dose (quantity of medicine), and frequency of repetition. The dose must be sufficient to trigger a healing response while avoiding unnecessary aggravation.
WHAT IS NOT HOMEOPATHY
Homeopathy proper differs from modern techniques that incorrectly call themselves homeopathic, yet prescribe:
- Mixtures of more than one medication at a time.
- Speculative practices based on theories such as the doctrine of signatures or other imaginative methods that select medicines based on unproven associations, physical properties (smell, taste, appearance), or chemical analysis rather than systematic trials (provings).â¶
- Protocol-based prescribing rather than individualized prescribing based on the law of similars.
- Medicines selected without reference to methodical trials or symptom similarity.
- Substances commercially manufactured as homeopathic drug products using a mechanism other than trituration/dilution and succussion.â·
STATEMENT OF ORGANIZATIONAL COMMITMENT
On behalf of our organization, we affirm that we understand and adopt this definition as our official standard for homeopathy. We commit to:
- Publicly displaying this definition on our website and in our educational materials.
- Ensuring that our leadership, faculty, and public representatives practice and teach in accordance with these principles.
- Using this definition as the foundation for our educational curricula and public representation of homeopathy.
- Maintaining these standards for anyone representing our organization in an official capacity, including publications and public presentations.
We acknowledge that Hahnemannian homeopathic practice requires adherence to the law of similars, single remedy prescribing, optimal posology, individualized treatment based on the totality of characteristic symptoms, and the use of medicines proven through systematic trials on healthy individuals.
