Homeopathic prescribing for chronic conditions in equine veterinary practice in the UK

Twelve Faculty of Homeopathy veterinarians recorded data systematically at 777 consecutive homeopathic appointments for horses over a period of 12 months. A spreadsheet enabled the recording of information, which included the date of appointment; horse and owner identity (anonymised); sex of horse; main medical problem treated; whether the condition was chronic or acute; whether the appointment was new or a follow-up; owner-assessed clinical outcome on a seven-point scale, ranging from -3 to +3, compared with the first appointment; homeopathic medicine(s) prescribed; and whether any conventional or other complementary/alternative medicine (CAM) was being used concurrently to treat the condition. Data from 289 horses comprised a total of 305 individual conditions identified as chronic in nature, of which 234 had a follow-up assessment. At the final appointment for chronic cases during the study period, 4.3 per cent were receiving conventional medication and 17.1 per cent were being given another CAM treatment in addition to homeopathy. The eight chronic conditions most frequently treated with homeopathy were: arthritis, headshaking, laminitis, chronic obstructive pulmonary disease, sweet itch, dermatitis, sarcoidosis and Cushing's syndrome.

Journeys in the country of the blind: entanglement theory and the effects of blinding on trials of homeopathy and homeopathic provings

The idea of quantum entanglement is borrowed from physics and developed into an algebraic argument to explain how double-blinding randomized controlled trials could lead to failure to provide unequivocal evidence for the efficacy of homeopathy, and inability to distinguish proving and placebo groups in homeopathic pathogenic trials. By analogy with the famous double-slit experiment of quantum physics, and more modern notions of quantum information processing, these failings are understood as blinding causing information loss resulting from a kind of quantum superposition between the remedy and placebo.

Outcomes from homeopathic prescribing in veterinary practice: a prospective, research-targeted, pilot study

BACKGROUND AND AIMS

Targeted research development in veterinary homeopathy is properly informed by the systematic collection and analysis of relevant clinical data obtained by its practitioners. We organised a pilot data collection study, in which 8 Faculty of Homeopathy veterinarians collected practice-based clinical and outcomes data over a 6-month period.

METHODS

A specifically designed Excel spreadsheet enabled recording of consecutive clinical appointments under the following headings: date; identity of patient and owner (anonymised); age, sex and species of patient; medical condition/complaint treated; whether confirmed diagnosis, chronic or acute, new or follow-up case; owner-assessed outcome (7-point Likert scale: -3 to +3) compared with first appointment; homeopathic medicine/s prescribed; other medication/s for the condition/complaint. Spreadsheets were submitted monthly by e-mail to the project organisers for data checking, synthesis and analysis.

RESULTS

Practitioners submitted data regularly and punctually, and most data cells were completed. 767 individual patients were treated (547 dogs, 155 cats, 50 horses, 5 rabbits, 4 guinea-pigs, 2 birds, 2 goats, 1 cow, and 1 tortoise). Outcome from two or more homeopathic appointments per patient condition was obtained in 539 cases (79.8% showing improvement, 6.1% deterioration, 11.7% no change; outcome not recorded in 2.4% of follow-ups). Strongly positive outcomes (scores of +2 or +3) were achieved in: arthritis and epilepsy in dogs and, in smaller numbers, in atopic dermatitis, gingivitis and hyperthyroidism in cats.

CONCLUSIONS

Systematic recording of data by veterinarians in clinical practice is feasible and capable of informing future research in veterinary homeopathy. A refined version of the spreadsheet can be used in larger-scale research-targeted veterinary data collection.

Is homeopathy possible?

As a therapeutic intervention, homeopathy is the target of increased scepticism because in the main, its remedies are diluted and succussed (potentized) out of material existence. This puts homeopathy seemingly at odds with the paradigm of conventional science, in particular, that atoms and molecules are the fundamental building blocks of all matter. Accordingly, homeopathy cannot work, so that any reported beneficial effects must, at best, be due to the placebo effect. The purpose of this article is to challenge that conclusion and to suggest that there may well be conventional science-based explanations of how homeopathy could be possible. Homeopathy's key principles are first described. Then the double-blind randomized controlled trial (RCT), the chief means by which homeopathic remedies and prescribing are tested, is shown to be based on a linear reductionism that is too blunt an instrument with which to test the efficacy of complex interventions such as homeopathy The memory of water hypothesis, as a mechanism for how potentized remedies might work, is reviewed, along with some evidence for its existence. A possible rationale for the water memory effect is proposed in terms of a dynamic 'ordering' of water's constantly switching network of intermolecular hydrogen bonds, induced by the manufacturing process of homeopathic remedies. This could lead to a long-range molecular 'coherence' between trillions of mobile water molecules. However, the water memory effect is an essentially pharmacological explanation of homeopathy's putative efficacy. It is pointed out that healing also entails an interaction between consenting beings. From this point of view, an explanation of any therapeutic procedure should include an attempt to describe the nature of the patient-practitioner interaction. From this perspective, a quantum theoretical treatment of the therapeutic process, involving a form of macro-entanglement between patient, practitioner and remedy (PPR), is advanced as another possible explanation of the homeopathy's efficacy. This shows that the reason double-blind RCTs deliver at best only equivocal results on homeopathy's efficacy is because it effectively breaks the PPR entangled state. A comparison is made between the entanglement-breaking effect of double-blind RCTs and the wave-function 'collapsing' effect of observation in orthodox quantum theory. The article concludes by suggesting that the memory of water and PPR entanglement are not competing but most likely complementary hypotheses, and that both are probably required in order to provide a complete description of the homeopathic process. While awaiting experimental evidence of these hypotheses, it is suggested that observations of clinical outcomes would be superior to RCTs for further testing homeopathy's efficacy.

Towards a New Model of the Homeopathic Process Based on Quantum Field Theory

BACKGROUND

Quantum theory's notions of non-locality and entanglement have previously informed attempts to model the therapeutic process. Of these, Weak Quantum Theory (WQT) and Patient- Practitioner-Remedy (PPR) entanglement are developing into mathematically- based models of homeopathy.

OBJECTIVE

The present study attempted to identify fundamental concepts within quantum field theory (QFT) that could be used to broaden the scope of PPR entanglement models, prior to constructing a more rigorous mathematical treatment.

METHODS

In QFT, particles and forces are considered as fully interacting relativistic quantum matter and force fields, respectively. These interactions are visualized graphically as spacetime Feynman diagrams. Further, these interacting field systems can have ground states with broken symmetry; the so-called Higgs field being responsible for this symmetry breaking. In the new model, patient, practitioner and remedy are imagined as fully interacting quantum-like fields; patients and practitioners in terms of quantum matter-type fields, and remedies and diseases as quantum interaction-type fields.

RESULTS

Disease manifestation by the Vital Force (Vf) could be an event similar to spontaneous symmetry breaking in QFT: the curative remedy acting to restore the broken symmetry of the Vf field. Entanglement between patient, practitioner, and remedy might be representable as Feynman-like diagrams.

CONCLUSION

QFT demonstrates that quantum properties can be physical without being observable. Thus, an underlying similarity in discourse could exist between homeopathy and quantum theory which could be useful for modelling the homeopathic process. This preliminary investigation also suggested that key elements of previous quantum models of the homeopathic process, may become unified within this new QFT-type approach.

Research on homeopathy: state of the art

In this paper, we review research on homeopathy from four perspectives, focusing on reviews and some landmark studies. These perspectives are laboratory studies, clinical trials, observational studies, and theoretical work. In laboratory models, numerous effects and anomalies have been reported. However, no single model has been sufficiently widely replicated. Instead, researchers have focused on ever-new models and experiments, leaving the picture of scattered anomalies without coherence. Basic research, trying to elucidate a purported difference between homeopathic remedies and control solutions has also produced some encouraging results, but again, series of independent replications are missing. While there are nearly 200 reports on clinical trials, few series have been conducted for single conditions. Some of these series document clinically useful effects and differences against placebo and some series do not. Observational research into uncontrolled homeopathic practice documents consistently strong therapeutic effects and sustained satisfaction in patients. We suggest that this scattered picture has to do with the fourth line of research: lack of a good theory. Some of the extant theoretical models are reviewed, including placebo, water structure, silica contamination, energy models, and entanglement models. It emerges that local models, suggesting some change in structure in the solvent, are far from convincing. The nonlocal models proposed would predict that it is impossible to nail down homeopathic effects with direct experimental testing and this places homeopathy in a scientific dilemma. We close with some suggestions for potentially fruitful research.
