When Samuel Hahnemann proposed homeopathy in 1796[20], he
based it on the idea that “Like cures like,” and that dilution increases
potency of a treatment. Diseases are caused by miasms, he further
alleged, -- predispositions to a particular disease. You’re likely not
familiar with the term, as miasms long have been disproven.
Not all homeopaths today believe in the so-called miasm theory, but
all homeopathy is based on like-cures-like (also long disproven). At the
core of the homeopathic beliefs is a fairly simple process:
You take the active substance
(whatever that may be) and usual y
Dilution
dilute it by putting one drop of it in
1 liter of alcohol or distilled water.
Then, you mix it well (according to some, keeping it aligned with the
center of the Earth), take 1 drop of this newly obtained substance and
put it in another fresh liter of alcohol or distilled water.
And then you do it again.
And again.
And again.
Many, many times.

Homeopathy
This obviously takes the ‘medicine’ to point where none of the
original molecules remain in a bottle of the finished product. That’s
a-ok, however, if you ask a homeopath, because the more diluted the
substance is, the more effective it becomes.
The idea is that the alcohol or distilled water will somehow
“remember”[21] the molecule and have an impact on your body. Right off the bat, this goes directly against all we know about science -- not
something one pharma company or another might be saying, but against
well-established, basic science. So the theory is fundamental y flawed.
What about the practice? Absolutely
implausible
Study after study has tried to find evidence or even just a workable
mechanism for homeopathy, but they’ve found the exact opposite.
There’s nothing behind homeopathy, and there’s no healing effect past
a placebo.
If water did have a “memory,” we would have to rewrite all of science as
we know it. Even ignoring the centuries of scientific research disproving
homeopathy, a simple thought experiment can help us understand why
it’s absurd.
Just imagine: in its history, water will have contacted literal y millions
of other substances, and by this thought process, it has a memory of
all of them -- so just drinking a glass of regular water should make
you immune to a swarm of diseases, right? So then, why even have
homeopathy? Water is natural y diluting all sorts of things, so we should
kind of be immune to everything, right?
Lastly, even if there were any active substance, and even if water
did have a memory, something that causes symptoms similar to the
X disease doesn’t cure said disease. That’s just wishful thinking, and
there is nothing to suggest that this works[22]. The scientific consensus is pretty strong in this case. Here are just a few studies.

Homeopathy
If water did have a “memory,” we would
have to rewrite all of science as we know
Homeopathy it. Even ignoring the centuries of scientific
studies
research disproving homeopathy, a
simple thought experiment can go a long
way when it comes to the process.
Unlike astrology, homeopathy studies abound. In just the past 5 years,
several thorough studies have disproved homeopathy. A 2014 paper by
Australia’s National Health and Medical Research Council found that
there are “no health conditions for which there was reliable evidence
that homeopathy was effective[23]. ” Furthermore, they write, “no good-quality studies” report that homeopathy works better than a placebo.
A year later, the same group combed through the results of 1,800
studies, again with the same findings[24].
Just one year later, Paul Glasziou, a leading academic in evidence based
medicine at Bond University, verified 176 trials of homeopathy, finding
“no discernible convincing effects beyond placebo.” He concluded[25]
that “there was no reliable evidence from research” that homeopathy
was effective for treating health conditions.
These aren’t new findings -- for decades, researchers have been
proving that homeopathy doesn’t work, and it’s dangerous to use it
instead of reliable treatments.
In 2005, Kevin Smith from the University of Abertay Dundee published
a paper concluding that since homeopathy is completely implausible,
it’s not only unscientific, it’s also unethical. In 2010, a British Medical
Journal study found that homeopathy can be particularly dangerous for
children, and is never recommended.
But why then do so many people stick by it? You often hear things
like “This worked for me” or “It’s the only thing that helped me.”

Homeopathy
Why homeopahy seems to work
a) unassisted natural healing - Your body is awesome at self-healing.
Some people are more resilient than others, but generally speaking, your
body heals itself all the time. It can handle even strong diseases on its
own.
b) the placebo effect - Simulated treatments are surprisingly effective
many cases -- the placebo effect has been documented in a number of
different situations. Combine this with your self-healing, and you get
quite a powerful tool.
c) the consultation effect - Modern research has shown that if you just
go to the doctor and receive a consultation, the care, concern, and
reassurance a patient experiences when opening up to a compassionate
caregiver (read: homeopath) can have a positive effect.
d) cessation of unpleasant treatment. Many times, homeopaths
recommend ceasing of conventional treatments. This is extremely
dangerous and should never be done without consulting an actual
medical doctor. Oftentimes, the conventional treatment causes some
unpleasant side effects, perhaps even more so than the disease’s
symptoms. When you stop taking the treatment, the side effects may go
away, but the disease stays and can get worse.
e) regression towards the mean - Many diseases and conditions are
cyclical -- the symptoms naturally get stronger then weaker over time.
Since patients tend to seek care when discomfort is greatest, it’s pretty
likely that the symptoms will naturally impove after the consultation (but
not because of it).
f) unrecognized treatments - An unrelated food, exercise, environmental
agent, or treatment for a different ailment may have occurred. Maybe
you drank a lot of green tea, or that trip to the ocean did wonders for
your lungs.

What harm can homeopathy do,
though?
i mean... it’s plain water, right?
(Yes)
Cautionary Tales
In 2002, one-year-old Isabel a Denley from Calgary was prescribed
medications for her epilepsy[27]. Instead of taking the meds, her parents consulted an iridologist, an applied kinesiologist, a psychic, and an
osteopath. They settle
d on a homeopathic treatment. She was still only
taking this homeopathic treatment when she died.
In 2009, another infant girl, Gloria Thomas, died of complications due
to eczema which was treated only with homeopathy[28]. Eczema -- let that sink in for a while. An easily manageable disease. By the time she
died, nine-month-old Gloria was the weight of an average three-month-
old, her body was covered with angry blotches, and her once-black
hair had turned completely white. Her parents were declared guilty of
manslaughter, but they still stood by their support for homeopathy.
These are not isolated cases. This is a serious issue. It may seem fun and
hip to choose homeopathy instead of the “nasty” drugs from a pharmacy,
but if you’re using homeopathy at the expense of medical treatments,
you’re putting yourself and others at risk. Please, don’t do this to yourself
or the ones you love. Consult a real doctor.

Homeopathy
A note on natural remedies
There is a lot of confusion with people mistaking homeopathy with
naturopathic treatments. That’s a separate discussion in itself, but for
now, let’s just say that the two things are very different. Natural reme-
dies (herbs, teas, plants, etc.) are not homeopathy. You should always
consult with your doctor or pharmacist before taking anything, and
only follow treatments recommended by an authorized physician.

Anti-Vaxxing
While homeopathy has been discussed in one form or another for a
long time, a more recent movement is sending ripples -- and causing a
lot of damage -- through the world: anti-vaxxers.
Talking about vaccines is almost always hyperbolic. They’ve single-
handedly ushered in a new age of medicine and are widely regarded as
one of the greatest medical breakthroughs of the modern era. While
they may not be perfect, they have historical y been the most effective
means to fight and eradicate infectious diseases, saving hundreds of
millions of lives since they were first introduced.
Smal pox, a disease caused by the variola virus, had existed for at
least 3,000 years and was one of the world’s most feared diseases until it
was eradicated by a col aborative global vaccination program led by the
World Health Organization. The last known natural case was recorded
in Somalia in 1977.

All states in the U.S. require
vaccinations for children to be
Consequences of enrolled in school. However, 18
the vaccine scare states allow parents to opt out
of vaccinations for their children
based on personal beliefs.
According to a 2016 report[28] issued by the American Academy of Pediatrics (AAP), vaccination prevented about 322 million illnesses
among children born between 1994 and 2013. In the US, vaccine
immunization campaigns against diseases like smal pox, diphtheria,
measles, and mumps have reduced disease incidence by at least 90%
-- even up to 99%. If you look elsewhere in the developed world, figures
are similar. Diseases that were once widespread and life-threatening are
now all but extinct.
In addition to saving the lives of our children, vaccination has
resulted in net economic benefits to society -- amounting to almost $69
billion in the United States alone. A study published by health economist
Sachiko Ozawa[29] reported that the $34 billion spent on immunization programs in the developing world resulted in savings of $586 billion
by reducing costs of illness and $1.53 trillion when broader economic
benefits were included.
Opposition to vaccines has been around for as long as vaccines
themselves, but this is something different. The anti-vaxxer movement
is a recent one, sparked by one particular fraudulent, long-disproven
paper which claimed that some vaccines can cause autism.
Wait, do you mean the whole vaccines / autism thing is based on one
paper?
Yes, and it gets even better.

Anti-vaxxers and the infamous
Wakefield paper
This association first sprouted in 1998 when Andrew Wakefield,
then a British surgeon, published a study in the prestigious medical
journal, The Lancet, suggesting that the measles, mumps, rubel a
(MMR) vaccine was increasing autism in British children. Although the
paper itself did not demonstrate a causal relationship between MMR
vaccination and autism, Wakefield released a video coinciding with the
paper’s publication claiming that a causal relationship did, in fact, exist.
The media loved Wakefield’s article because it struck an emotional
chord with the public, sparking fear and outrage. But for scientists,
it raised all sorts of red flags. For starters, no one could replicate his
results -- essential for any scientific claim. Everything blew up after an
investigation by journalist Brian Deer [30] in 2004.
Deer’s investigation showed that Wakefield purposely manipulated
medical histories to support his claims. Deer also showed that Wakefield
wanted to use the MMR scare for his own financial profit.
According to Fiona Godlee, the editor in chief of the BMJ[31], the article by Wakefield “was based not on bad science but on a deliberate
fraud,” and Wakefield grossly and intentional y manipulated the data as
he willed. Pseudoscience is often about power and profit.
The paper was official y retracted by the Lancet, and Wakefield was
stripped of his clinical and academic credentials. Several times, he
was given the opportunity to try and replicate his research, which he
refused. To this day, however, Wakefield makes a living perpetuating
the false views that vaccines cause autism.

More Anti-vaxxers, more diseases
The media loved Wakefield’s article because it rang an
emotional chord with the public, sparking fear and outrage.
Many major (and honest) studies[32] have been carried out since, demonstrating without any doubt that MMR vaccines do not engender
a higher risk of autism or colitis. Not a single study found a connection
between the two, but the damage has already been done.
The number of parents who refuse to vaccinate their children has
grown, surpassing 3%. Many parents feel like vaccines are no longer
necessary because they haven’t heard of the diseases they’re vaccinating
against. That’s right: vaccines have been so effective that people forget
why we need them -- and the diseases are bouncing back. Talk about
irony!
A 2013 paper[33] linked falling immunization rates to the recent resurgence of vaccine-preventable diseases. California, for instance --
a hub for the anti-vaxxing movement -- saw 9,120 cases of whooping
cough (pertussis) in 2010, which is more than any year since the
whooping cough vaccine was introduced in the 1940s. During this
particular outbreak, ten infants died of the disease.
. . .
The American Association of Pediatricians reports[28]
that up to 87% of pediatricians have encountered a
parent who refused to vaccinate their child, a figure
which has been steadily increasing.

In Europe, anti-vaxxing has led to a dramatic increase of measles
cases, with over 40,000 cases in 2018 (so far), and 37 fatalities.
Although vaccines have proven themselves as one of the greatest
public-health achievements of the 20th century, people throughout
history have found various reasons to distrust them. Some found it too
counter-intuitive that exposure to a disease could provide protection,
others believed vaccination violated God’s wil , or simply felt that
mandatory vaccination violated personal liberty.
In a sense, today’s vaccine-related “urban myths” are the manifestation
of a longstanding distrust of inoculation:
