Homeopathy
Homeopathy
Founded by Samuel Hahnemann in the late 18th
century
Hahnemann had some prior training in conventional
medicine but he found the practice barbaric and
cruel .
Greatest popularity in 19th century with a revival in
the late 20th century.
Homeopathy watching the Horrors of Allopathy
Benefits of Homeopathy
Generally less invasive and has less side effects than
conventional medicine.
Associated with healthier lifestyles
Patients often do report improved symptoms
Even if unsupported by Medical Community its not
hurting anyone (some debate)
Potential criticisms of Homeopathy
Lacks scientific evidence
Experiments supporting homeopathy
often poorly conducted and noreplicable
by the scientific community
The Three Pillars of homeopathy are in
conflict with the ideology that makes up
Modern Science
THREE PILLARS OF HOMEOPATHY
1. The principal of Similars
Remedy causes symptoms similar to the
disease in healthy people.
Quinine and Malariacured malaria but
caused feverish symptoms in healthy
individuals
THREE PILLARS OF HOMEOPATHY
2. The Vital Force
Harmonize a person on all levels of their being
Diseases result from disharmonized Vital Force
Based on a belief system rather than science
Belief system that has a long history dating back to the
Hippocrates.
THREE PILLARS OF HOMEOPATHY
3. Potentization
POTENCY
CONCENTRATION
1
THREE PILLARS OF HOMEOPATHY
3. Potentization
Greater potency is achieved as the solution
becomes diluted and violently agitated.
Most debated aspect of homeopathy.
Many studies done with differential results
Results tend to depend on the experimenter.
Potentiation Concentration Scale
D scale: denotes the extent of dilution, i.e. D10
concentration=10-10
C scale: denotes the number of 1:100 dilutions
performed.
D60=C30: Dilution advocated by Hahnemann for
most purposes
C15: very unlikely that any of the original molecules
of mother tincture still remaining.
Explanations for Potentiation
Human basophil degranulation triggered by
very dilute antiserum against IgE. Davern E, et
al.
Many other studies found similar results even
at dilutions that could probabilistically do not
contain any parent molecules.
Usually explained by the concept of water
memory

anaphylaxis and immune complex deposition from rabbit and
human basophiles. Nature 1974; 249: 581-582.
Homeopathy is still not understood,
however his efforts started a new era of
rigorous scientific investigation of the
field

Specific information must have been transmitted during the
dilution /shaking process via some molecular organization
occurring in the water
History of the Memory of Water
There were no methodological flaws apparent at the
time. James Maddox, Nature Editor
"There are good and particular reasons why prudent
people should, for the time being, suspend judgment

Committee:
James Randi: magician-cum-paranormal researcher
Walter Stewart: physicist and freelance debunker
at the US NIH
History of the Memory of Water
No memory effect was observed in the
blinded experiments.
Although no fraud was found, the lack of
reproducibility led Nature to conclude that
there was no substantial basis for Benvenistes
claim.
History of the Memory of Water
Benveniste and several collaborators worked
to find the underlying mechanisms to the
results on his original paper.

Homeopathy Research
Homeopathy Research
1. Experimental research
study efficacy of
homeopathic remedies
2. Basic research elucidate
nature of homeopathic
remedies
3. Clinical trials studies
clinical efficacy
4. Theoretical models
EXPERIMENTAL RESEARCH
in vitro, cell systems, or in vivo
Many models (both plant and animal) exist
but only a few have been replicated
independently (and quality often poor)
Examples:
Jacques Benveniste (1988) IgE degranulation
Independent replication of more recent studies
Crosslinking of IgE molecules triggers granule
exocytosis with the release of histamine and loss of
metachromatic straining of basophil granules by a
basic dye
Serially diluted anti-IgE
antiserum & measured
basophil degranulation at
each concentration
Results
Successive peaks of degranulation from 40-
60% of the basophils over dilutions of anti-IgE
that range from 102 to 10120
Less than one molecule of Ab is present when
anti-IgE antiserum is diluted to 1014
Strengths HOWEVER
Control: cells incubated Observer bias
in conditions identical to Some participating
those with anti-IgE laboratories withdrew
antiserum gave no because effect not
significant degranulation consistent with results (not
(antihuman IgG reported)
antiserum) Variability of the positive
Blind double-coded results was smaller than
procedures the statistically expected
6 different laboratories error or microscopical cell
(in 4 countries) count and found no effect
of higher dilutions
More Recently (2005)
Staining and microscopical counting of basophils prone
to subjective influences (even if method blinded)
Experimenters used flow-cytometry to measure
basophil degranulation
Determines % CD63-expressing basophils (those activated)
CD63 expression directly correlates with histamine release
All experiments performed with a blinded and
randomised arrangement of dilutions and controls
Aimed to independently replicate former studies, which
showed similar findings as Benveniste
Results
In contrast to former studies, no large effect of
highly diluted histamine solutions on anti-IgE
induced basophil degranulation was found
BASIC RESEARCH
elucidating the nature of homeopathic remedies
To understand mechanism, need to find a
plausible theory and experimental backing to
clarify how a highly diluted substance can
affect a biological system
Must explain how a biological effect can be
brought about without a sufficient number of
molecules of the active agent (found in
homeopathetic remedies)
CLINICAL RESEARCH
Many scientists Homeopathy violates
natural laws and thus any effect must be a
placebo effect
Public & some physicians use of and belief
in effectiveness of homeopathy is widespread
Is the effect seen with homeopathic remedies
equivalent to that seen with placebo?
If the hypothesis that all clinical effects of
homeopathy are due to placebo is true:
1. All properly conducted
place-controlled trials on
homeopathy would be
comparing one placebo to
another
2. Thus, overall results should
vary randomly around a
zero difference between
groups
Results not
compatible with
placebo hypothesis
However, insufficient
evidence that any
single type of
homeopathic
treatment is clearly
effective in any one
clinical condition
Systemic Reviews of Clinical Trials on
Homeopathy for Specific Conditions
Author Indication N and Conclusions
trial type
Taylor Allergic 4 RCTs Isopathic nosodes different from placebo on both
et. al. conditions subjective and objective measures
Jacobs Childhood 3 RCTs Individualized homeopathic treatment decreases
et. al. diarrhea the duration and number of stools in children with
acute diarrhea, but sample size small
Ernst Delayed- 8 double- Evidence does not support hypothesis that
conset muscle blinded homeopathic remedies are affective for muscle
soreness trials soreness
Vickers Influenza-like 7 RCTs Probably reduces duration of influenza-like
& Smith syndrome syndromes; further trials needed
Barnes Postoperative 4 RCTs; 2 Available evidence positive but several caveats
et. al. ileus CCTs preclude definitive conclusion
Efficacy/effectiveness paradox: Disputed
evidence that homeopathy is different from
placebo yet there is documented usefulness in
general practice
~70% of all patients using homeopathy report they are
considerably improved after treatment (effects remain
stable during follow-up periods of 2-5 years)
Before clinical homeopathy research can
proceed with success, needs a viable theory
THEORETICAL MODELS
Local
Conventional scientific positivism
Non-local: quantum theoretical concepts
Complementarity
Entanglement
Local Mechanisms
Homeopathic remedies behave in a way
similar to any other medicine
The production process produces some kind
of template, image, or imprint of the original
substance, and this information is the active
ingredient
Local Mechanisms
Hydrogen bonds and van der Waals
interactions
Electric fields can be modified and modulated
by their surrounding
Laws of thermodynamics?
Examples of local mechanisms
Remaining material on surfaces
Nanobubbles
Remaining particle clusters
Ethanol solution complexity
Natural water clusters redox molecules
produced from water
Non-local Hypotheses
Correlations are somehow established
between patient, practitioner and remedy,
ultimately leading to an observed change in
the patients state of health.
Even more controversial than local
mechanisms: quantum theory applicable in
our macroscopic domain??
Non-local Hypotheses
Quantum entanglement: property of the
quantum mechanical state of a system
containing two or more objects, where the
objects that make up the system are linked in
such a way that the quantum state of any of
them cannot be adequately described without
full mention of the others, even if the
individual objects are spatially separated.
Water Memory
Empirical Approaches
Dr. Masaru Emoto.
He claims about the
resonance
present in words and
how these vibrations
change in health and
disease.
Emotos experiments
Rice experiment
Three separate
treatments to beakers
containing rice and
water:
1. Thank the flask or say
something nice
2. Tell nasty and rude
phrases.
3. Ignore it.
Emottos Water Crystals (2003)
2000 people (Tokyo) prayed to water samples stored
on a electromagnetic shielded room. (CA,USA).
Control samples were in other place.
Pictures of both samples were blindly taken.
After that, the pictures were shown to 100 judges.
(They did not know which crystal was fro which
sample)
Statistically, judges prefer the prayed crystal.

Water crystals
Shape dependant on
the kind of vibration
given to the water
sample.
Water memory explanation?
In 2003, the physics journal: Physica published an
experiment on water memory
Louis Rey.
Thermoluminescence:
The technique involves bathing a chilled sample
with radiation. When the sample is warmed up, the
stored energy is released as light in a pattern that
reflects the atomic structure of the sample
Water memory explanation?
Much to our surprise, the
thermoluminescence glows
of the three systems were
substantially different
Control Double distilled

Deuterium Different
arrengement of the

10x 10-5 M of Sodium
Chloride and Lithium

Water memory explanation?
What did they measure?
Zinc aggregates Non Noble metals
Gold aggregates Noble metals
SAED (Selected Area Electron
Diffraction)
What info we could get from this paper? #1
The change in the properties of the treated
water (sucussion) is dependant on time.
Sucussion or shaking leads to the formation of
clusters.
How are these clusters formed?
Theodore Grotthus (1806)
The shaking of
homeopathic dilutions
generate dissipative
structures.
The physicochemical
parameters electrical
conductivity and heat of
mixing are in fact
functions of the
number, size and shape
of the dissipative
structures
Expert Opinions Against Homeopathy
Steven Novella, Yale University, New Haven, CT.
The law of similars & law of Infintesimals: no
biological plausability.
Homeopathy is still a philosophy-based
medicine
Hahnemann had his theory of illness, largely
based on the notion of miasms.
Theorists invoking quantum mechanics?
Expert Opinions Against Homeopathy
Donald Marcus. Baylor University, Waco, TX.
Professor Ernst, Exeter University in England:
based on over 20 reviews since 1997 believes
there is no evidence homeopathic remedies
differ from placebos
ENHS conclusion: insufficient evidence to
support the use of homeopathy.
The Lancet: theres no point in making
further investments in research in clinical
trials in homeopathy.
Expert Opinions Against Homeopathy
No FDA regulations
Safety concern: some homeopathic practioners
recommend against vaccination.
Some people who practice homeopathy are
unqualified to perform general medical
evaluations and may miss serious and treatable
conditions.
The Heisenberg principle concerns atomic and
subatomic particles and it does not invalidate
Newtonian physics: no justification for taking
this concept from physics and applying it to
health care.
Is Homeopathy Unethical?
Unethical aspects of homeopathic dentistry
Homeopathic doctors/hospitals relatively common and
there are a fair amount of homeopathic dentists in the
UK.
Many documented effects of homeopathy attributed to
placebo and the fact that Homeopathic professionals
do not acknowledge this is against ethical guidelines
defined by the Society of Homeopaths
Most studies referenced for the benefits of
homeopathic medicine have since been discredited by
scientific community.
From the prospective of Scientific
Community
At the moment the evidence of clinical trials
is positive but not sufficient to draw definitive
conclusions because most trials are of low
methodological quality and because of the
unknown role of publication bias.
Conclusion
Jury is still out on whether or not water
memory truly exists.
More research needed, but as of today
Potentiation and the other pillars of homeopathy
are not supported by the scientific community.
Conclusion
Some empirical evidence shows structural cahnge
in water but biological plausibility still uncertain.
Both Homeopathic practitioners and scientific
community remain steadfast in their beliefs.
Possible that the truth lies somewhere between
these two extremes
