Homeopathy revisited
NEW YORK, NY. Homeopathy is one for the fastest growing modalities of natural
medicine. For the past two decades sales of homeopathic medicines have increased by
20 per cent to 30 per cent per year in both Europe and the United States. The French
Medical Association recently called for full official recognition of homeopathy and its
inclusion in standard medical training. Nevertheless, physicians in North America are
generally sceptical about homeopathy because they believe its claims are incompatible
with current Western medical knowledge.
Dr. Daniel Eskinazi of the Columbia University College of Physicians and Surgeons has
now scrutinized this belief and has reached the conclusion that the principles of
homeopathy are not in conflict with accepted biomedical dogma. The two main principles
of homeopathy are that "like cures like" and that homeopathic medicines so dilute that no
molecules of the original substance are present can still exert an effect. The principle of
"like cures like" means that a substance which in high concentrations induces illness in
healthy people can in very dilute concentrations cure the same illness in sick people.
Dr. Eskinazi points out that there are several pharmaceutical drugs (e.g. aspirin, digoxin,
epinephrine) which can produce one effect at low doses and the opposite effect at higher
doses - or can produce one effect in sick people and another in healthy people. He
concludes that the paradoxical effects of these drugs are very similar to the effects that led
Samuel Hahnemann to formulate the first principle of homeopathy.
Dr. Eskinazi goes on to investigate the aspect of dilution. Many homeopathic remedies
are diluted to the point where the concentration of the active substance in the solution
(usually distilled water) is less that 1 in 100,000 parts. This is a very high dilution indeed.
However, there are many substances in conventional medicine that are active at even
higher dilutions. Just one molecule of certain pheromones is enough to cause a
noticeable effect. Leukotrienes release luteinizing hormones at concentrations as low as
10 to the minus 20th mol/L and proline effects sea anemones at concentrations so low
that no proline molecules would theoretically be present in the solution.
He suggests that there are many examples in conventional biomedical research where
substances have been found to be biologically active in the same low concentrations as
homeopathic medicines used in standard practice. He concludes that the claims and
principles of homeopathy are not incompatible with current biomedical
knowledge.
