Characterisation of Aqueous Ultra-high Homeopathic Potencies: Nanoparticle Tracking Analysis.

Area of Science:

• Nanotechnology
• Homeopathy Research
• Physical Chemistry

Background:

• Previous research suggested the material nature, including nanoparticles (NPs), of high homeopathic potencies.
• The current study aimed to verify these claims using nanoparticle tracking analysis (NTA).

Purpose of the Study:

• To verify the presence and characteristics of nanoparticles in high homeopathic potencies.
• To compare nanoparticle properties in homeopathic dynamisations (DYNs) versus simple dilutions (DILs) and controls.
• To investigate the influence of starting material, solvent, and container on nanoparticle characteristics.

Main Methods:

• Prepared six independent serial dilutions of common homeopathic medicines (soluble and insoluble) following European Pharmacopoeia standards.
• Utilized nanoparticle tracking analysis (NTA) to analyze homeopathic dynamisations (DYNs), dilutions (DILs), and controls.
• Assessed the impact of container material (glass or PET) on solvent controls.

Main Results:

• Observed nanoparticles (20-400 nm) in all DYNs, DILs, and controls (except pure water), indicating a material basis.
• Nanoparticle size and distribution differed between DYNs and controls, varying with source solubility.
• Homeopathic potentisation (DYNs) showed increased nanoparticle number, size, aggregation, and brightness compared to simple dilutions (DILs), even beyond 11c potency.

Conclusions:

• Homeopathic medicines contain nanoparticles with specific properties, even beyond Avogadro's number, suggesting potentisation is not simple dilution.
• Nanoparticle characteristics are influenced by the starting material, solvent, container, and manufacturing method.
• The observed nanoparticles are likely a complex mixture, potentially including nanobubbles and atmospheric/container elements.
