A commentary on Harry van der Zee’s article “Amma Resonance Healing Foundation – Peter Chappell’s legacy for Africa”, published in Homeopathy in Practice (Winter/Spring 2025). A tribute to Peter Chappell (1941–2023), who lived fully and accomplished what he came here to do, and to Harry van der Zee, who carries his work forward.
In the latest issue of Homeopathy in Practice, Dutch homeopath Harry van der Zee summarises twenty years of work by the Amma Resonance Healing Foundation in sub-Saharan Africa. He writes as a clinician with a six-year epidemiological study from Bukavu behind him, and with thousands of documented cases from fourteen African countries. The subject reaches directly into the questions Quintessence Forum has been opening for years.
Who Peter Chappell was
Peter Chappell (1941–2023) was a British homeopath with an unusual background. He began his career as a research and development engineer in the aerospace industry. By the age of twenty-five he held three United States patents in air navigation and what would later become computing technology. He came to homeopathy around the age of thirty and in 1978 co-founded the UK Society of Homeopaths. He later built Micropath, the first homeopathic software that worked in real time inside the consulting room.
In the 1990s Peter set out to bring classical homeopathy to countries where it barely existed. Through the London College of Classical Homeopathy (LCCH), of which he was an envoy, he organised training programmes in roughly twenty countries across Eastern Europe, the Middle East, and Latin America. Slovakia was among the first, starting in 1992. Bulgaria followed in 1993, then the Czech Republic, Croatia, Romania, and others. Many homeopaths in this region, including the present author, began their training in those programmes. LCCH no longer exists. The classical homeopathic schools that today operate across Central and Eastern Europe trace much of their lineage back to Peter’s decision to come and teach.
Harry van der Zee played his own role in this region. He was among the principal organisers of the Dutch–Indian School of Classical Homeopathy, which delivered high-quality teaching in Košice, Slovakia, and Prague, Czech Republic, in the nineties. Without these two men, the homeopathic landscape in our part of Europe would look noticeably poorer.
The hug from Amma and the path to Source
In 2000, shortly before his sixtieth birthday, Peter received a hug from the Indian guru Amma (Mata Amritanandamayi) and, by his own account, in that moment received the inner message that he was to go and work on the HIV/AIDS epidemic in Africa. He described the episode openly in an autobiographical article published in the last year of his life. Several turning points in his life were framed this way, through meditation and inner messages. He said the same of his founding of the Society of Homeopaths in the UK, which followed a message received in meditation.
So he closed his London practice, mortgaged his property, and in October 2001 travelled to Addis Ababa. He spent months trying to find a homeopathic answer to the African form of AIDS using classical methods. The vast majority of the patients responded favourably, but he realized that with millions infected a collective approach was needed. For finding a remedy based on the totality of symptoms as expressed in dozens of cases he took, the existing repertories and materia medicas were not sufficient. He then developed what he called a reverse engineering approach. He took the totality picture of the disease and imprinted it directly into a carrier using a method he called Source technology. In 2002 the first remedy of this kind was born, and he named it PC1.
The principle echoes Hahnemann’s genus epidemicus, a single remedy fitting an epidemic. Peter pushed the principle further. He created not just one remedy for one epidemic, but a technology to make a remedy for any condition with a definable totality. He called these remedies the Second Simillimum, a second similar that fits the totality of the disease and complements the first simillimum, which fits the totality of the patient.
Peter fully disclosed how the imprinting was done to only a few people, including Harry. He spoke of tapping into the vital essence of Being and of working with consciousness as a field. To summarize it, one could say that when the mind cecomes totally silent, prayer becomes creation. Sourcemedicine.zone, the sister organisation of ARHF for the Western context, later expanded this framework. The original name PC remedies (Peter Chappell) was extended into a parallel name, Source Resonances (SR). The two are interchangeable. ARHF still uses PC in Africa because all the manuals and instructional videos for African health workers carry that name. The ecosystem now covers infectious diseases, trauma, and chronic conditions. Some remedies are dispensed as water-based potencies by three European pharmacies (Helios in the UK, Hahnemann Apotheek in the Netherlands, Apotheke z. heiligen Florian in Austria). Others are delivered as imprinted sound files.
Data from the field
Van der Zee documents three principal lines of work.
HIV/AIDS. A comparative study in Kenya (2017–2018) across three groups: ARVs alone, ARVs combined with PC1, and PC1 alone. Six-month follow-up. The PC1-only group consistently produced the strongest outcomes, with an average CD4 increase of 19,81 % compared to 2,48 % in the ARV-only group, and a viral load decrease of 53,35 % compared to 34,63 %. The study was not randomised. The figures are robust and converge with observations from 2002 onwards in more than ten countries.
Malaria. A six-year epidemiological study in Bukavu (DRC) covering a population of over 370 000. PC240m was made available in health areas 1 to 5. Areas 6 to 10 served as a transition group. Areas 11 to 13 served as control. By 2023 the areas covered by PC240m showed an 80 % reduction in malaria-related deaths among children under five compared to 2018 baseline. The social return on investment reached 40 dollars in healthcare savings for every dollar spent on prevention.
LEAP. A sound-based form of resonance designed for schools. The information is imprinted into music and played to children at the start of the school day. Across sixteen schools, absenteeism dropped from 13,22 % to 4,56 % within a single school year. Marega Primary School, after four years of LEAP, ranked second-best primary school in Kenya in the national examinations.
These data are not peer-reviewed RCTs. They are naturalistic field studies, and van der Zee presents them as such. Their weight comes from scale (hundreds of thousands of people, two decades of work), from consistency (the same outcomes in different countries with different teams), and from the fact that they are anchored in measurable indicators: deaths, hospitalisations, CD4 counts, viral loads, school examination results.
Theoretical framework: water carries information
Van der Zee names the whole approach Information Medicine. He does this deliberately to bypass the ideological barrier surrounding the word homeopathy. The theoretical foundation rests on three pillars.
The first is Gerald Pollack’s research on the fourth phase of water (exclusion zone, EZ). Water at hydrophilic surfaces, which includes most of the water inside our cells, forms a structured lattice resembling a liquid crystal. This lattice can store information through modifications in the positions of oxygen and hydrogen atoms. In the human body, 99 % of all molecules are water molecules. Water in this light is no longer a passive solvent.
The second pillar is quantum biology (Al-Khalili, McFadden) and the concept of coherence as a quantum phenomenon supporting living processes. Disease appears here as a loss of coherence, an increase in entropy. Healing means delivering information that restores coherence.
The third pillar comes from the work of Manzalini, Galeazzi, Marc Henry, Madl, and Renati on quantum electrodynamics and water. They offer a mechanistic framework for what homeopaths have observed for two hundred years.
This framework is hypothetical and that needs to be said openly. Serious physicists are at last willing to look for a mechanism behind the phenomena that clinical practice documents.
A bridge to what we do at QF
Here the subject touches the core of Quintessence Forum.
Owen Barfield described the evolution of human consciousness as a movement from original participation, through the separation of subject and object, towards what he called final participation. This is the conscious co-creation of reality, where human and world are no longer two separate entities. Classical homeopathy operates exactly in this mode. Hahnemann’s vital force, Scholten’s plant phases and his mineral periods and stages, Sankaran’s vital sensation, signature as a reading of the deep structure of the world. All of this presupposes a world that speaks and a consciousness that listens. The materialist paradigm rules out such a world a priori.
Bernardo Kastrup, in his analytical defence of idealism, argues that matter is a presentation of consciousness, not the other way around. Federico Faggin reaches a similar conclusion through quantum information. Iain McGilchrist describes how Western thought has locked itself into the mode of the left hemisphere, which sees isolated objects, and lost access to the right, which perceives relationships and wholes.
Peter Chappell’s life fits naturally into this frame. He did not describe his own method only in engineering terms, even though he was originally a rocket engineer. He described it through consciousness and through a connection to source. The African data Harry van der Zee has gathered are important here for one specific reason. They show that when one works with information (imprinted in water or in sound) at the level of the disease totality, the organism responds. It responds in a measurable, reproducible way, in populations. Idealism does not follow from this directly. What follows is a more concrete observation: information has causal power at the biological level, which the materialist framework cannot easily explain.
Open questions
PC technology is not classical constitutional homeopathy. It is prescribed collectively, on the basis of an epidemic picture, with no individualisation. To a classical homeopath this can look like a reduction. For van der Zee it is a necessity of the field. In sub-Saharan Africa, where homeopaths number in the dozens per million, individual prescribing simply cannot be delivered, but, as experience shows, is also not required in the majority of cases.
It is worth asking whether PC remedies are a limit case of the same principle, or a parallel line with its own internal logic. Peter himself called them the Second Simillimum, suggesting he was consciously moving past Hahnemann’s frame. More striking is his later discovery. When PC remedies were introduced into Western practice for chronic disease, their effectiveness fell. They worked less consistently as stand-alone treatment and in combination with individualised classical prescribing. In Africa, for epidemics: yes. In the West, for chronic disease, not on their own. This finding deserves further reflection on the nature of Peter’s method.
The mechanistic hypothesis around water is promising. It is not yet established science. Clinical effectiveness and theoretical foundation are two distinct questions and should not be conflated.
Conclusion
Van der Zee’s article matters for two reasons. It documents that information medicine works in the field, at the population level, with objective epidemiological indicators. It also opens space for serious discussion of what happens when water carries information and the organism responds.
Both of these matter to QF. The clinical side, because we treat patients ourselves. The paradigmatic side, because we are living through the change of paradigm itself. The African data are among the strongest empirical arguments available today that the new paradigm is not speculation. It is a description of a world that already works.
Peter Chappell lived fully. He did what he came here to do. From a research engineer with three patents to a homeopath rebuilding a profession in a dozen post-communist countries; from a London consultant to a man who mortgaged his home at sixty to go and work on AIDS in Ethiopia; from clinician to inventor of a new way of making remedies. He left behind tens of thousands of people alive who would otherwise be dead, a foundation that carries the work forward, and a body of questions that homeopathy and the wider culture will be working through for a long time. Harry van der Zee, ARHF, Source Medicine, and the African health workers who quietly distribute these remedies in their communities are now the bearers of that legacy. Thank you, Peter. Thank you, Harry.
