Video summary
This lecture critically examines homeopathy, a medical practice founded by Samuel Hahnemann in 1796 that relies on principles fundamentally at odds with established science. The core concepts include the "law of similars," which suggests that a substance causing symptoms in a healthy person can cure those same symptoms in a sick person, and the "law of infinite dilution," which claims that remedies become more potent as they are diluted. This leads to preparations where no molecules of the original substance remain, such as a 30C dilution containing one molecule in a container millions of times larger than Earth. Proponents argue that water retains a "memory" of these substances through processes like succussion (vigorous shaking), but this is dismissed as magical thinking rather than a physical phenomenon supported by chemistry or physics.
The lecture details the bizarre and often absurd methods used to prepare and select homeopathic remedies, ranging from diluting concrete from the Berlin Wall to using duck liver for flu treatments, despite the original substance being completely absent. The preparation process involves serial dilutions that can reach levels like 200C, which is so extreme that it would require more universes than exist in the observable cosmos to find a single molecule of the original ingredient. Furthermore, the selection of remedies often involves subjective methods like repertories that match patient histories to lists of symptoms, or even dowsing with pendulums, leading to treatments for conditions as severe as electrical car failures or malaria based on non-existent biological entities like *Oscillo-cinum*.
Despite its historical popularity and current availability over the counter, homeopathy has been thoroughly debunked by rigorous scientific testing. Clinical trials consistently show that homeopathic remedies perform no better than placebos, and systematic reviews confirm that any perceived benefits are due to factors like the placebo effect, natural recovery, or the attention of the practitioner rather than the remedy itself. The lecture highlights dangerous cases where patients relied on homeopathy instead of effective conventional treatments, resulting in severe illness or death from conditions like malaria, asthma, and epilepsy. Ultimately, the evidence against homeopathy is as strong as fundamental scientific laws, proving that it is an ineffective practice that poses significant risks when used to replace proven medical care.

welcome back I'm Dr Harriet Hall and
this is lecture five in a series of 10
lectures on science-based medicine the
topic of this lecture is
Homeopathy many of the people who use
Homeopathy don't have any understanding
of what it is I've run across Highly
Educated medical professionals who
thought Homeopathy was just some kind of
herbal medicine when they found out what
it really was boy was their face red
Homeopathy is actually incredibly silly
here's a simple explanation of
Homeopathy that illustrates just how
ridiculous it
is if coffee keeps you awake dilute
coffee will put you to sleep the more
dilute the stronger the effect dilute
coffee acts as a sleeping pill and more
dilute coffee acts as an even stronger
sleeping pill
if you dilute all of the coffee
molecules out of the water the water
will remember them and the effect will
be even
stronger and the water's memory of
coffee can be transferred to a sugar
pill by dripping the water onto a sugar
pill and allowing it to
evaporate quackwatch calls Homeopathy
the ultimate fake and it's also been
called delusions about
dilutions in lecture three I explained
how a single individual DD Palmer
invented Chiropractic all by himself on
a single day in
1895 in lecture four I explained how a
single individual Dr noer invented ear
acupuncture all by himself in
1957 a single individual Samuel hanaman
invented Homeopathy all by himself too
in
1796 to set the scene let's think about
the state of medicine in hanan's
lifetime science-based medicine was far
in the future diseases weren't well
defined they thought malaria was caused
by bad air there was no germ Theory no
antibiotics no anesthesia no sterile
techniques no systematic testing of
treatments doctors of his time did more
harm than good they were treating
patients on the basis of a false theory
of the four humors in an attempt to
balance those humors they were bleeding
patients emptying their colon with
purgatives and emptying their stomachs
with aics they were poisoning them with
medicines like Mercury they were killing
people hanaman was right to criticize
his colleagues but he was wrong about
Homeopathy he intended Homeopathy to be
a Kinder gentler more effective
treatment system that would replace
allopathy that was a word he coined to
disparage doctors saying that they only
treated the symptoms not the disease
itself and that they treated with
opposites instead of
similars that wasn't even an accurate
characterization of what doctors were
doing in his day and it certainly
doesn't describe what doctors do today
most of us object strenuously to being
called alpath doctors the term is used
as an insult and it has no legitimate
meaning just as one personal experience
with a deaf janitor LED DD Palmer to
invent Chiropractic a personal
experience with tree bark led hanaman to
invent homeopathy and in both in both
cases they misinterpreted a single
experience and extrapolated wildly from
it sinona is a tree that grows in South
America the bark of the tree was used to
treat fevers if the fever happened to be
be from malaria syona worked because it
contained quinine and effective malaria
treatment hanaman was skeptical and he
was experimenting on himself with large
doses of
sinona he developed symptoms that he
thought were typical of
malaria he was wrong his symptoms
weren't typical of malaria and today we
think he probably had some unusual
reaction to something in the bark anyway
his experience led him to deduce that
the same remedy that caused a symptom
could relieve it so he tried treating
with similars he found that some people
got worse before they got better to
reduce the side effects he kept lowering
the dose by diluting the remedy here are
the two basic principles of Homeopathy
first the law of similars like cures
like a remedy will cure a disease in a
sick person if it causes the same
symptoms as the disease when given to a
healthy
person if epicac makes a healthy person
vomit it ought to cure vomiting in sick
people now the idea that like cures like
is really just a form of sympathetic
magic second the law of infinite
decimals the smaller the the larger the
effect that would mean the less sugar
you put in your coffee the sweeter it
tastes this law is obviously false and
it's contrary to everything we know
about chemistry pharmacology and
physics hanaman had another Revelation
succussion when he made a home visit the
patient was more likely to improve than
if he saw the patient in his office now
it's easy to see how a home visit might
make more of an imp more of an
impression on the patient and might
enhance the contextual effects of the
doctor patient encounter but hanaman
thought up his own
explanation the remedies got jostled in
his saddle bags as he rode his horse to
the patient's
home he imagined that the jostling
increased the potency of the remedy he
never thought to test this idea by
comparing jostled and non- jostled
remedies because he didn't think like a
scientist he just assumed he was right
and he recommended that when remedies
were prepared the solution should be
potentized after every step of dilution
by pounding the bottle repeatedly
against something he used a leatherbound
book today some preparers succuss the
remedies by hand against a leather pad
and some use
machines the remedies may be sold as a
liquid or as a tiny pill when the
dilution is complete the solution can be
dripped onto tiny sugar pills and
allowed to
evaporate some remedies like Granite
diamond and platinum are not soluble in
water or alcohol so they're prepared by
trituration they grind them up with a
mortar and pestle and then dilute them
with lactose milk sugar one triturated
remedy is Berlin wall they take a tiny
bit of ground up concrete from the
Berlin wall and they mix it with 100
parts of sugar
lactose then they take one part of the
resultant mixture and mix it with 100
parts of lactose they repeat that
process two UND
times one homeopath said it was such a
powerful remedy that she had to store it
away from her other remedies she kept it
out of the garden
shed it is used to treat feelings of
confinement and oppression Shifty eyes
Terror asthma and
headaches according to a Homeopathy
journal the wall in Berlin seems to have
been immersed with the psychological
emotions and thoughts of
mankind again
magical
thinking the dilutions are where it
really boggles the mind they're labeled
as X for 10 and C for 100 a 6X dilution
means one part of Remedy was diluted
with 10 parts of water or alcohol and
one part of the resulting mixture was
diluted with another 10 parts of water
and so on for a total of six times in
the SE dilutions one part of the remedy
is mixed with 100 parts of water at each
step 6x ounts to a solution of one part
in a million 6 C amounts to one part in
10 trillion the process is
exponential by the time you get to the
13 C or the 26x level there isn't a
single molecule of the original remedy
left a 13c dilution is equivalent to
diluting 13 of a drop of the original
substance in all the water on
Earth a typical homeopathic remedy is
30C at the 30C level it would take a
container 30 million times the size of
the Earth to hold enough water to make
sure you were getting at least one
molecule of the original substance
another way of looking at it is that for
one patient to get one molecule you
would have to give 2 billion doses per
second to 6 billion people for 4 billion
years it gets
worse the most popular flu remedy is
sold as a dilution of 200 C
that's 10 to the 400th
power the number of atoms in the
observable universe is 10 to the 80th
power my brain froze when I tried to
figure out how many universes it would
take to find one
molecule and 200 C isn't the limit there
are remedies that are diluted far more
above the Thousand C Level they're
designated as m 1 m equal 1,00 C we're
able to make those calculations thanks
to avagadro avagadro's number allows us
to calculate the number of atoms or
molecules in a volume of a chemical
substance based on the molecular mass
the first calculations were done in
1865 22 years after hanan's
death now we know that remedies of 13c
and above are nothing but water hanaman
didn't have any way of knowing that when
his followers found out they had three
choices one one they could abandon the
dilute remedies two they could accept
metaphysical explanations assuming that
the water somehow remembers molecules
that are no longer there or three they
could look for a scientific
explanation most of them accepted option
two that water somehow absorbs the
vitalistic essence of the remedy and
remembers it some of them are still
working on option three trying to find
an explanation that scientists could
accept homeopaths try to justify their
remedies by comparing them to
vaccines that's a false analogy vaccines
contain measurable amounts of antigens
and they work by a known mechanism
homeopathic remedies contain no active
molecules and they work by
Magic they invoke hormesis now that's a
phenomenon where a low dose of a
chemical May trigger the opposite
response to a high dose but hormesis is
only known to apply in certain cases
it's not a universal phenomenon by any
means and it describes a response to a
low do not to no
dose they invoke water clusters clusters
of water molecules do form but they only
last for trillionths of a second there's
no way they could register or transmit
information there's been wild
speculation about quantum entanglement
that's the kind of thing that leaves
Quantum physicists rolling on the floor
laughing they keep doing ridiculous FL
experiments trying to prove that water
can
remember one of the most famous
experiments was the Ben vist Affair
jacqu Ben vist claimed that he could
detect biological activity of antibodies
after the antibodies had been diluted
out and were no longer
there the study was published in nature
with the condition that his lab would be
inspected a team including the journal's
editor and Chief and James Randy visited
the lab and found a number of problems
the researchers were true believers who
bordered on religious fervor their
blinding procedures and controls were
inadequate the positive results were
from a single technician and when the
team instituted more rigorous controls
the results couldn't be
reproduced other labs tried to reproduce
their findings and
failed and the results weren't even
compatible with homeopathic Theory the
effect went up and down with subsequent
delusions instead of steadily
upwards Ben vist is the only person to
have won two IGN Nobel Awards both for
his work on
Homeopathy his second IG Nobel award was
for his alleged discovery that not only
does water have a memory but the
information can be transmitted over
telephone lines and the
internet drugs are tested with
randomized Placebo control trials
homeopathic remedies are tested with
provings these were originally done with
an undiluted remedy and later with a 30C
dilution
healthy volunteers take it and they keep
a detailed Diary of every symptom they
experience for an unspecified
unspecified length of time as long as
they feel like doing it sometimes for
months they write down
everything I felt angry I burped my big
toe itched at 11:00 p.m. I dreamed about
my
dog there's no attempt to compare those
symptoms to a control group then they're
inter erated to elicit even more
symptoms instead of looking for
commonalities they just pull all the
different reports from different provs
and the whole mishmash of reported
symptoms is used to guide treatments
with that
remedy people mean different things by
Homeopathy in classic Homeopathy only a
single remedy is used at a time in
combination Homeopathy a mixture of
remedies for the same symptoms is used
today homeopathic remedies are sold over
the counter for self-prescription
something that I don't think hanaman
would ever have
condoned when homeopaths take a
patient's history they spend as much as
an hour interviewing the patient they go
into excruciating detail about the chief
complaint they try to pin down the time
of onset and its possible relation to
life events they ask about concomitants
seemingly unrelated symptoms like weak
ankles or unusual sleeping positions
they ask about General symptoms Syms
like sluggishness feelings of hot or
cold Restless sleep changes in appetite
they ask about family history did
anything stressful happen to the
patient's mother during her pregnancy
they asked seemingly off-the-wall
questions like what do you love most
about life what bothers you the most
about other people what are you teased
the most
about here's a typical history that a
homeopath obtained from a patient with
uterine fibroids that's a tumor of the
uterus he wrote down that she was
loquacious loud anxious doesn't want to
live desperate feels humiliated ashamed
used rejected angry offended lonely
religious affections relationship
problems workaholic absence of nurturing
in childhood parents fighting uterine
fibroids constipated retains
fluid the fibroids themselves are near
the end of the and the homeopath May
interpret other things in the history as
more
important after eliciting all these
relevant and irrelevant symptoms the
homeopath looks up the symptoms in a
reparatory book it lists symptoms by
parts of the body here's an excerpt from
a a section on a facial
expression the patient with fibroids was
anxious for anxious 66 different
remedies are listed there are other
facial expressions like anxious when
child is lifted from cradle anxious
during downward movement astonished
besided bewildered changed childish cold
distant and that's just the ABCs it
continues right on down the alphabet for
20 more categories including happy
intoxicated old looking and stupid for
each of these categories of facial
expression there is a different list of
corresponding remedies the homeopath
looks up the symptoms he imagines are
the most important and he selects the
remedy that best matches
those the Repertory is organized by
symptoms the next step is to use another
book The homeopathic Materia medicia
that's organized by remedy it lists all
the symptoms that provings have
associated with each remedy here's an
example for a remedy called natum
muriaticum the entry for naturum
muriaticum lists symptoms in all of
these areas mind head Eyes Ears Nose
face stomach abdomen rectum urine male
female respiratory heart extremities
sleep skin fever and
modalities some of the examples from uh
from these areas include eyelids heavy
anemic headache of school girls
constipation and diarrhea yes both of
those sensation of coldness of heart
s hot and
perspiring hang
nails dreams of robbers oily skin warts
on palms of hands chill between 9 and
11:00 a.m. the list goes on and on for
several
Pages what is naturum
muriaticum it's common table
salt how can anyone seriously believe
that table salt causes all those
symptoms and can cure
them hanaman listed 67 remedies today
there are over 2,000 with over 1,300
officially recognized by the hpus the
homeopathic pharmacopia of the US here
are some examples Berlin Wall eclipsed
Moonlight South Pole of a magnet dogs
ear wax tears from a weeping young girl
fossilized dinosaur bone rattlesnake
venom arsenic Poison
Ivy the homeopath follows the patient's
progress and if the patient is not
getting better he assumes that the first
remedy was correct but that the
situation has changed so he reevaluates
and prescribes a different remedy the
homeopath is constantly re-evaluating
and there's always another remedy to
try aggravations are a good sign if the
symptoms get worse it means the remed is
working
if the symptoms get better it means the
remedy is working too so you can't lose
if the remedy isn't working the
homeopath can blame the patient for
having inadvertently used antidotes that
prevented the remedy from working for
instance he drank coffee he didn't get
enough sleep he used a cell phone he ate
spicy
foods why did some patients fail to
respond hanaman developed his theory of
myms to explain the failures of
homeopathy aathy he decided that all
disease was caused by three myms
syphilis psychosis or Gara and Sora
scabies or itch he decided that myms had
to be cleared before the remedy could
work he thought this led to an improved
approach to selecting
remedies this all sounds so silly but
scientists don't reject something just
because it sounds silly we still need to
test whether it works
homeopaths site epidemics and early
successes where patients treated with
homeopaths did better than patients
treated with conventional
medicine but those successes were
because doctors of that era were doing
more harm than good Homeopathy did
nothing so the results were
better homeopaths point to high levels
of patient satisfaction but that doesn't
mean it works remember all the ways that
patients can be satisfied by bogus
remedies and a charismatic provider
remember medicine's beautiful idea no
matter how convinced you are you still
need to test every
treatment and Homeopathy was tested as
early as 1832 in a hospital in Russia
one Ward got conventional treatment one
Ward got homeopathic treatment and one
Ward got no treatment but was given fake
pills made of breadcrumbs and cocoa to
make them think they were being
treated the no treatment Ward had the
best
outcomes that means that Homeopathy did
no good and the conventional treatments
of the day didn't do any good either in
those days before science-based medicine
it was better for patients to steer
clear of both conventional doctors and
homeopaths and just just let nature take
its course with no
treatment it's a wonder they didn't
conclude that breadcrumbs and cocoa were
an effective
treatment Homeopathy has been tested
over and over since that time modern
clinical trials have not shown that
Homeopathy was is effective David Riley
said either Homeopathy works or control
trials don't in a sense he was right
control trials don't work very well for
studying Homeopathy and other
implausible health claims as my
colleague Kimbell Atwood put it Trials
of ineffective claims championed by
impassioned Advocates will appear to
yield equivocal rather than merely NE
negative outcomes the inevitable
continual citations of dubious reports
will lead some to judge that the
aggregate data are weakly positive or
that the treatment is better than
Placebo so they just call for more
studies Dr Atwood also pointed out that
Homeopathy can't possibly work as
claimed is the sort of basic science
that can reasonably be called
established
knowledge is it realistic to assume that
this level of evidence can be overthrown
by ambiguous clinical trials of dubious
design the evidence against homeopathy
ay is as strong as the evidence that the
Earth is spheroid rather than flat that
the planets orbit the sun rather than
the earth that mass and energy are
conserved that the Earth is several
billion years old and that species
evolved by a process of variation in
natural
selection J Shelton wrote a book about
Homeopathy Homeopathy how it really
works it's listed in the course guide he
concluded that Homeopathy often helps
people but the remedies don't contribute
it helps through non- remedy factors
like unassisted natural healing
attention suggestion contextual effects
of the treatment encounter regression to
the mean cessation of harmful or
unpleasant treatments lifestyle assisted
healing and different perceptions of
internal reality versus external
reality when results of clinical trials
disagree with each other we can try to
resolve the disagreements with
systematic analyses of all the data
of 11 systematic reviews of Homeopathy
only two were
positive when those two were reanalyzed
with the lowquality trials omitted they
were
negative2 the most favorable systematic
review said that overall Homeopathy
worked better than Placebo but it didn't
work better than Placebo for any
specific
condition that doesn't compute it it's
like saying broccoli is good for
everyone but it's not good for men men
or women or
children Homeopathy is a good example of
changing attitudes about cam in 1900
there were 10,000 homeopathic physicians
in the US along with 79 homeopathic
hospitals and 22 homeopathic medical
schools as scientific medicine gained
ground Homeopathy lost ground the last
us homeopathic medical school closed in
1920 by 1950 the last homeopathic
Hospital en closed and by 1970 there
were only 75 homeopaths still practicing
in the US but today home Homeopathy is
having a Revival and remedies are sold
over the counter in pharmacies ocelo
oxum can be found on the shelves of any
local pharmacy it's the most popular
homeopathic remedy and perhaps the
funniest one ever during the Spanish flu
epidemic of 1918 a f a French doctor
named Joseph Roy
looked at the blood of flu victims under
a microscope and he thought he had
observed an oscillating bacterium he
named it ocelo
cacus no one else ever saw it he was
probably confused by Brownie and motion
he was probably seeing tiny particles of
dust or whatever that were being jostled
by the constant movement of water
molecules but he thought he'd discovered
a new pathologic organisms and when he
thought he'd spotted the the same
organism in the liver of a duckling he
assumed that a homeopathic flu remedy
could be made from the duck liver today
it's manufactured from the heart and
liver of the muscovi duck diluted by one
in 100 to the 200th power to get one
molecule of the original extract the
patient would have to consume an amount
of the of the remedy many orders of
magnitude greater than the number of
atoms in the observable universe osoc
coxim is one of the top selling drugs in
France and it brings in $15 million a
year in the US but it's an impossibly
dilute solution of something that never
even existed in the first
place here's my version of the recipe
for ocelo coxm take a bit of duck liver
dilute the duck out of it hope the water
remembers the duck and hope the memory
of duck cures
cold in
reality All That Remains is the quack
would you believe there are homeopathic
vaccines they're prepared with noodes
material taken from the saliva blood pus
urine or disease tissue from victims of
the
disease Health Canada has officially
licensed homeopathic remedies to prevent
flu polio measles and
pessis I reported one homeopath to
Homeland Security CU I figured they'd
like to find out where he got his
smallpox and Anthrax noodes because if
he could get them so could
terrorists do you believe in magic a
well-known homeopath described how a car
was fixed
homeopathically it appeared to be having
electrical problems so they wrote
electricus 2 200C on a piece of paper
and they placed it near the engine the
problem was
resolved sometimes dowsing is used to
Select Remedies the customer takes a
pendulum to the store and holds it over
each remedy until it swings the right
way
provings are done where the subject
doesn't actually take the substance but
meditates about it or dreams with it
under the pillow or prepares it by
trituration or writes it on a piece of
paper and keeps the paper close to his
body homeopaths have treated patients by
telephone or
telepathy in grafting one potentized
sugar pill is added to a bottle of inert
pills and it converts them all to
remedies there are even Homeopathy first
aid kits for accidents and
emergencies you can buy one of these for
$54.99 on
amazon.com it contains 18 vials of sugar
pills labeled 200C they're recommended
for accidents injury infections GI
problems burns muscle pain etc for
certain illnesses they advise depending
on severity seek medical
care the list includes anaphylaxis
Animal B bone injuries third degree
burns carbon monoxide poisoning drug
overdose electrocution eye injuries
poisoning puncture wounds and
shock it's appalling to think that
patients are left to their own
assessment and might think that these
conditions were not severe enough to
Merit Medical
Care there's a hilarious YouTube video
making fun of these kits a young man
goes out to save the world he drops a
pill from each bottle into a local
stream that runs to the ocean
so the remedies will eventually reach
everyone on Earth in an even more dilute
form this will eliminate all the
diseases the kid instructions cover from
heart attacks and strokes to throttling
and
drowning people say even if Homeopathy
is only a placebo what's the harm in
using it it can't cause any side effects
so it's safer than other treatments and
patients seem to like it but it can be
very dangerous if it's used in place of
effective treatments
janz podgorsek was harmed in Slovenia a
homeopath named darer ersen treated him
with homeopathic drops to pre prevent
malaria he got malaria anyway and then
the homeopath treated him with
homeopathic remedies for the malaria he
died in 1996 at the age of
42 the homeopath license was revoked and
he got two years
probation jacn alderslade was harmed she
was a a 55-year-old woman who lived in
Ireland her homeopath told her to stop
taking her asthma medication and she
died of an asthma
attack and little Isabella dley was
harmed she was a 13-month-old baby in
Australia and her epilepsy was treated
with Homeopathy and she
died and the remedies are not always
benign sometimes remedies sold over the
counter is homeopathic are low delusions
like one in a 100 that they actually
contain enough active ingredient to harm
patients a teething remedy Highland's
baby teething tablets was recalled
because babies developed symptoms of
belladon
toxicity Zam caused adults to lose their
sense of
smell manufacturing standards were LAX
and the amount of active ingredient in
the products
varied a skeptic group in the UK did an
experiment they sent a young woman to
various homeopaths for advice about area
prophylaxis for a trip to Africa 10 out
of 10 advised homeopathic protection
instead of standard
prophylaxis one explained they make it
so your energy your living energy
doesn't have a kind of malaria shaped
hole in it the malarial mosquitoes won't
come along and fill that in the remedy
sorted
out there was a case reported in the
British medical journal where a woman
relied on homeopathic vaccine during a
trip to Togo she developed a severe case
of malaria spent 2 months in intensive
care and had multiple organ
failure water passes through the oceans
in the water cycle and it gets succussed
by the waves if it can remember why
wouldn't it remember fish
poop there's no such thing as absolutely
pure water or absolutely clean glassware
tiny amounts of contaminants are always
present and dust and pollen grains fall
out of the air into open containers of
water there are far more molecules of
contaminant in a homeopathic dilution
than there are molecules of the original
substance so how could the water know
which substance it's supposed to
remember this poster pretty much says it
all if water has a memory then
Homeopathy is full of and
sugar to end with here's a t-shirt that
says Homeopathy making all
difference since 1796
in the next lecture I'll talk about
naturopathy
