Background: Patient-practitioner-remedy (PPR) entanglement postulates non-local triadic interaction between patient (Px), practitioner (Pr) and potentised medicine (Rx), resulting in the patient's journey to cure; the in-depth homeopathic interview is considered a major contributing factor in this process. Also, by modelling entelechy, a quantised gyroscopic analogue of the Vital Force (Vf) has been developed. Objective: To discover whether entanglement notions explain the mode of action of homeopathy during the treatment of epidemic diseases, when the individualising in-depth homeopathic interview is neither possible nor necessary. Method: The current Vf wave equation applies specifically to the in-depth patient/practitioner consultation in chronic dis-ease. A generalised form of the Vf wave equation, an earlier hypothesis based on quantum field theory (QFT) and PPR entanglement were all re-investigated. Results: The generalised Vf wave equation was found applicable in 3 main conditions: acute self-limiting, chronic and epidemic dis-ease. In the latter, a single, coherent Vf epidemic ‘wave function' covering all susceptible beings could be identified, which, after practitioner intervention, disappears. Analogies were drawn between groups of atoms in a p-doped semiconductor and a collection of susceptible beings in an epidemic. Here, genus epidemicus is likened to an ‘n-type dopant', which forms a ‘p-n junction' with the dis-ease. Using the QFT hypothesis/metaphor, genus epidemicus acts as a ‘gauge field' restoring ‘global invariance' to the symmetry-broken, symptom-expressing Vf, i.e., restoring health. Conclusion: Entanglement hypotheses/metaphors may have application in the homeopathic therapeutic process beyond the one-to-one in-depth interview, and so are relevant to describing the mode of action of homeopathy during treatment of epidemic disease.
