Serially Succussed and Diluted Homeopathic Preparations: The State of the Science

Speakers: Joyce Frye, DO, MBA, David Anick, MD, PhD, Stephan Baumgartner, PhD, Rustum Roy, PhD, Philippe Belon, MD, John Ives, PhD, Jean Sainte-Laudy

Homeopathy is a whole medical system that therapeutically uses ultra high dilutions (UHD) prepared by serial logarithmic dilution and intense succussion of a mother tincture, typically in water-ethanol mixtures. Because of the high dilution factor, it is often argued that treatment effects are nonspecific or placebo. However, many randomized placebo controlled double blind clinical trials demonstrate effects of homeopathic potencies superior to placebo. Accepting these results, it must be concluded that the dilution medium adopts a specific structure related to the initial mother tincture. Many theories have been proposed to explain how the efficacy of UHD: most are based on conjecture and do not provide readily testable hypotheses. This State of the Science symposium will bring together leading international researchers in the properties of these dilutions. Presenters will address the following topics and discuss the most promising avenues for future research:

The structure of liquid water: novel insights from materials research; relevance to homeopathy
Three well-known phenomena in materials research illuminate the controversy on the plausibility of homeopathic claims. First, the structure of condensed noncrystalline matter leads to a new view on the structure of liquid water at or near ambient temperatures. The most distinctive aspect of the structure of water is the nanoheterogeneity of the assemblage of molecular units. The key bonding feature is the presence of van der Waals bonds among the various structural units. Additionally, epitaxy provides a universally accepted route of transferring structural information from a (crystalline) solid to a liquid without the presence of any part of the solid in the changed liquid. Finally, the succussing process generates two routes to changing the structure of water: the pressure generated, and the nanobubbles of air created which could become "permanent" colloids.

High sensitivity 1H-NMR spectroscopy of homeopathic remedies made in water
Homeopathic remedies made in water were examined via high sensitivity proton nuclear magnetic resonance spectroscopy (NMR) Using the NMR technique of presaturation, signals could be reliably detected for H-containing species at concentrations as low as 5 mM. In the combined spectra of 57 remedy and 46 control samples there were 35 positions where discrete signals were seen that should theoretically have been absent from the spectrum of pure water.

Thermoluminescence of ultra-high dilutions of lithium chloride and sodium chloride. The phenomenon of thermoluminescence is an interesting tool to study the structure of solids, mainly the appearance of ordered crystal imperfections. Starting from liquids, which were turned into stable solids by low-temperature cooling, it was demonstrated that the thermoluminescent glow of irradiated hexagonal ice consisted in two major peak areas having well defined emission spectra.

Enzyme stabilization by glass-derived silicates in homeopathically prepared solutions
Enzyme assays with horseradish peroxidase and acetylcholine esterase were used to analyze serially succussed and diluted solutions (SSD) prepared in glass and plastic containers. Aqueous SSD preparations starting with various solutes, or water alone, were tested using colorimetric assays for their ability to affect enzyme activity and stability in dilute solution. Both enzyme stability in dilute solution and enzyme activity were enhanced in SSD solutions prepared in glass containers, but not those prepared in plastic containers, compared with enzyme stability and activity in plain water. Flow cytometric analysis of negative feedback of high histamine dilutions on human basophils. Three different protocol designs were used to optimize the analysis of the biological activity of histamine dilutions at the two target dilutions 10-4 M (2C) and 10-32 TMC (16C).

Flow cytometry clearly demonstrated that high dilutions of histamine may elicit an inhibition of IgE dependant and IgE independent basophil activation (anti-IgE and fMLP) both for dilutions containing histamine molecules (2C) and dilutions theoretically free of histamine molecules (16C).

Plants as a tool for basic research in homeopathy: State of the knowledge
Plants have been used in investigating the effects of homeopathic dilutions, starting with simple systems such as germination rate, and culminating in sophisticated phytopathological systems. Many studies yield evidence for specific effects of homeopathic potencies, nested with interesting features such as reduction of inter- and intra-experimental variability and differential effects of single potency levels.
