Treat with extreme caution

Homoeopathic medicine is founded on a bogus philosophy. Its continued use is a drain on NHS resource

Two years ago, a loose coalition of like-minded scientists wrote an open letter to chief executives of the National Health Service Trusts. The signatories simply stated that homoeopathy and other alternative therapies were unproven, and that the NHS should reserve its funds for treatments that had been shown to work. The letter marked an extraordinary downturn in the fortunes of homoeopathy in the UK over the following year, because the overwhelming majority of trusts either stopped sending patients to the four homoeopathic hospitals, or introduced measures to strictly limit referrals.

Consequently, the future of these hospitals is now in doubt. The Tunbridge Wells Homoeopathic Hospital is set to close next year and the Royal London Homoeopathic Hospital is likely to follow in its wake. Homoeo paths are now so worried about the collapse of their flagship hospitals that they are organising a march to deliver a petition to Downing Street on 22 June. Local campaign groups are being formed and patients are being urged to sign the petition.

Homoeopaths believe that the medical Establishment is crushing a valuable healing tradition that dates back more than two centuries and that still has much to offer patients. Homoeopaths are certainly passionate about the benefits of their treatment, but are their claims valid, or are they misguidedly promoting a bogus philosophy?

This is a question that I have been considering for the past two years, ever since I began co-authoring a book on the subject of alternative medicine with Professor Edzard Ernst. He was one of the signatories of the letter to the NHS trusts and is the world's first professor of complementary medicine. Before I present our conclusion, it is worth remembering why homoeo pathy has always existed beyond the borders of mainstream medicine.

Homoeopathy relies on two key principles, namely that like cures like, and that smaller doses deliver more powerful effects. In other words, if onions cause our eyes to stream, then a homoeopathic pill made from onion juice might be a potential cure for the eye irritation caused by hay fever. Crucially, the onion juice would need to be diluted repeatedly to produce the pill that can be administered to the patient, as homoeopaths believe that less is more.

Initially, this sounds attractive, and not dissimilar to the principle of vaccination, whereby a small amount of virus can be used to protect patients from viral infection. However, doctors use the principle of like cures like very selectively, whereas homoeopaths use it universally. Moreover, a vaccination always contains a measurable amount of active ingredient, whereas homoeopathic remedies are usually so dilute that they contain no active ingredient whatsoever.

A pill that contains no medicine is unlikely to be effective, but millions of patients swear by this treatment. From a scientific point of view, the obvious explanation is that any perceived benefit is purely a result of the placebo effect, because it is well established that any patient who believes in a remedy is likely to experience some improvement in their condition due to the psychological impact. Homoeopaths disagree, and claim that a "memory" of the homoeopathic ingredient has a profound physiological effect on the patient. So the key question is straightforward: is homoeopathy more than just a placebo treatment?

Fortunately, medical researchers have conducted more than 200 clinical trials to investigate the impact of homoeopathy on a whole range of conditions. Typically, one group of patients is given homoeopathic remedies and another group is given a known placebo, such as a sugar pill. Researchers then examine whether or not the homoeopathic group improves on average more than the placebo group. The overall conclusion from all this research is that homoeopathic remedies are indeed mere placebos.

In other words, their benefit is based on nothing more than wishful thinking. The latest and most definitive overview of the evidence was published in the Lancet in 2005 and was accompanied by an editorial entitled "The end of homoeopathy". It argued that ". . . doctors need to be bold and honest with their patients about homoeopathy's lack of benefit".

An unsound investment

However, even if homoeopathy is a placebo treatment, anybody working in health care will readily admit that the placebo effect can be a very powerful force for good. Therefore, it could be argued that homoeopaths should be allowed to flourish as they administer placebos that clearly appeal to patients. Despite the undoubted benefits of the placebo effect, however, there are numerous reasons why it is unjustifiable for the NHS to invest in homoeopathy.

First, it is important to recognise that money spent on homoeopathy means a lack of investment elsewhere in the NHS. It is estimated that the NHS spends £500m annually on alternative therapies, but instead of spending this money on unproven or disproven therapies it could be used to pay for 20,000 more nurses. Another way to appreciate the sum of money involved is to consider the recent refurbishment of the Royal Homoeopathic Hospital in London, which was completed in 2005 and cost £20m. The hospital is part of the University College London Hospitals NHS Foundation Trust, which contributed £10m to the refurbishment, even though it had to admit a deficit of £17.4m at the end of 2005. In other words, most of the overspend could have been avoided if the Trust had not spent so much money on refurbishing the spiritual home of homoeopathy.

Second, the placebo effect is real, but it can lull patients into a false sense of security by improving their sense of well-being without actually treating the underlying conditions. This might be all right for patients suffering from a cold or flu, which should clear up given time, but for more severe illnesses, homoeopathic treatment could lead to severe long-term problems. Because those who administer homoeopathic treatment are outside of conventional medicine and therefore largely unmonitored, it is impos sible to prove the damage caused by placebo. Never theless, there is plenty of anecdotal evidence to support this claim.

For example, in 2003 Professor Ernst was working with homoeopaths who were taking part in a study to see if they could treat asthma. Unknown to the professor or any of the other researchers, one of the homoeopaths had a brown spot on her arm, which was growing in size and changing in colour. Convinced that homoeopathy was genuinely effective, the homoeopath decided to treat it herself using her own remedies. Buoyed by the placebo effect, she continued her treatment for months, but the spot turned out to be a malignant melanoma. While she was still in the middle of treating asthma patients, the homoeopath died. Had she sought conventional treatment at an early stage, there would have been a 90 per cent chance that she would have survived for five years or more. By relying on homoeopathy, she had condemned herself to an inevitably early death.

The third problem is that anybody who is aware of the vast body of research and who still advises homoeopathy is misleading patients. In order to evoke the placebo effect, the patient has to be fooled into believing that homoeopathy is effective. In fact, bigger lies encourage bigger patient expectations and trigger bigger placebo effects, so exploiting the benefits of homoeopathy to the full would require homoeopaths to deliver the most fantastical justifications imaginable.

Over the past half-century, the trend has been towards a more open and honest relationship between doctor and patient, so homoeopaths who mislead patients flagrantly disregard ethical standards. Of course, many homoeopaths may be unaware of or may choose to disregard the vast body of scientific evidence against homoeo pathy, but arrogance and ignorance in health care are also unforgivable sins.

If it is justifiable for the manufacturers of homoeopathic remedies in effect to lie about the efficacy of their useless products in order to evoke a placebo benefit, then maybe the pharmaceutical companies could fairly argue that they ought to be allowed to sell sugar pills at high prices on the basis of the placebo effect as well. This would undermine the requirement for rigorous testing of drugs before they go on sale.

A fourth reason for spurning placebo-based medicines is that patients who use them for relatively mild conditions can later be led into dangerously inappropriate use of the same treatments. Imagine a patient with back pain who is referred to a homoeopath and who receives a moderate, short-term placebo effect. This might impress the patient, who then returns to the homoeopath for other advice. For example, it is known that homoeopaths offer alternatives to conventional vaccination - a 2002 survey of homoeopaths showed that only 3 per cent of them advised parents to give their baby the MMR vaccine. Hence, directing patients towards homoeo paths for back pain could encourage those patients not to have their children vaccinated against potentially dangerous diseases.

Killer cures

Such advice and treatment is irresponsible and dangerous. When I asked a young student to approach homoeopaths for advice on malaria prevention in 2006, ten out of ten homoeopaths were willing to sell their own remedies instead of telling the student to seek out expert advice and take the necessary drugs.

The student had explained that she would be spending ten weeks in West Africa; we had decided on this backstory because this region has the deadliest strain of malaria, which can kill within three days. Nevertheless, homoeopaths were willing to sell remedies that contained no active ingredient. Apparently, it was the memory of the ingredient that would protect the student, or, as one homoeopath put it: "The remedies should lower your susceptibility; because what they do is 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 remedies sort it out."

The homoeopathic industry likes to present itself as a caring, patient-centred alternative to conventional medicine, but in truth it offers disproven remedies and often makes scandalous and reckless claims. On World Aids Day 2007, the Society of Homoeopaths, which represents professional homoeopaths in the UK, organised an HIV/Aids symposium that promoted the outlandish ambitions of several speakers. For example, describing Harry van der Zee, editor of the International Journal for Classical Homoeo pathy, the society wrote: "Harry believes that, using the PC1 remedy, the Aids epidemic can be called to a halt, and that homoeopaths are the ones to do it."

There is one final reason for rejecting placebo-based medicines, perhaps the most important of all, which is that we do not actually need placebos to benefit from the placebo effect. A patient receiving proven treatments already receives the placebo effect, so to offer homoeopathy instead - which delivers only the placebo effect - would simply short-change the patient.

I do not expect that practising homoeopaths will accept any of my arguments above, because they are based on scientific evidence showing that homoeopathy is nothing more than a placebo. Even though this evidence is now indisputable, homoeopaths have, understandably, not shown any enthusiasm to acknowledge it.

For now, their campaign continues. Although it has not been updated for a while, the campaign website currently states that its petition has received only 382 signatures on paper, which means that there's a long way to go to reach the target of 250,000. But, of course, one of the central principles of homoeopathy is that less is more. Hence, in this case, a very small number of signatures may prove to be very effective. In fact, perhaps the Society of Homoeopaths should urge people to withdraw their names from the list, so that nobody at all signs the petition. Surely this would make it incredibly powerful and guaranteed to be effective.

When heritage becomes hate: why my home town of Charlottesville needs to address its complex past

After an invasion of white supremacists, we need to see what our history means today.

Watching a tragedy happening in slow motion, without any way to stop it - that’s how it has felt to be from Charlottesville, Virginia in the summer of 2017. A city that used to always get voted “happiest town in the USA” when I was growing up was the target this weekend of an ugly white supremacist movement whose roots spread far from the city.

It was a huge surprise when we won the lottery of Nazi flags, with our stupid old statues that have become icons of international fascism, with a park named after a distantly forgotten old man becoming a site of struggle for an attempted racist coup of the United States. Our first reaction is: they aren´t from here. Our second: make them go away. Our third: a realisation we need to examine the way that our own ways of life, which we thought so harmless, have inspired such horrible feelings in strangers.

Maybe for my African-American classmates at high school the statue of Confederate general Robert E Lee, and the park when it was still named after him rather than Emancipation Park, always meant violence. Pulling the statue down says no more about the historical Lee than tearing down Lenin in '89 says about socialism. We've been invaded by people pretending to protect us from invasion, and the symbols of our past will never matter as much as living people do.


The invaders picked our town, probably, because Virginia was a confederate state, and was in fact where the southern gentry used to live. Lee exemplified this tradition. He was son of Lighthorse Harry Lee, a hero of the revolutionary war and governor of Virginia, and is a descendant of one of “Virginia’s first families,” the aristocratic Englishmen who emigrated to Virginia when it was a British colony. He is part of Charlottesville's heritage, and perhaps not even all that shameful a part. He opposed the secession of the confederacy, supported the reconstruction after the war, including giving rights to recently freed slaves. Not exactly woke, but for a confederate general, not as bad as some.

We were taught at Venable Elementary School that he fought only reluctantly, to defend his land, not slavery. In the version we learned, one would imagine Lee being very opposed to people from the Midwest coming to Virginia in cars with Ohio license plates to murder Virginians. Many non-racist Virginians, including quite a few friends, respect Lee deeply - the same is true in towns like New Orleans where other Lee statues are being taken down. Yet if once we could fool ourselves into thinking that the statue didn't represent hatred and racial hierarchies, we can't anymore. The discussion of local history has turned into one of national identity. The statue should be gone by Christmas. 


The real hero of Charlottesville is the town’s founder, Thomas Jefferson, who was among the most enigmatic of the founding fathers, idealistic and hypocritical - a real American, in other words. His idea of the gentleman farmer is also part of our heritage. It was an alternative to Hamiltonian industrial capitalism, but lost out in the tustle to shape American history. Much like English contemporaries such as William Cobbett, Jefferson believed in a rural ideal, reading poetry by morning, farming by afternoon, playing the harpsichord by night. His thought is also present in our beautiful "academical village" of the University of Virginia which he also founded. It is one of UNESCO’s few world heritage sites in the United States, so I guess it is part fo the globe's heritage as well, and it is also where the white supremacists stomped around with their tiki torches.

It’s time for us to stop being romantic about Jefferson, too. The statue in our minds needs to come down. We can recognize the great parts of his work, of his thought, in Charlottesville today, but we can also recognise that he allowed himself to use violence to dominate others, that he owned slaves and raped them. And we can recognise that equivalent scenarios continue to play out today, and will continue to play out until we are willing to face the truth.

There can be no more excuses. It’s not about Jefferson, or Lee, after all. We use monuments, statues, heroes, to inspire ourselves. In the end, the “truth” about Jefferson or Lee is a matter of trivia and history. Today, for every white male in America, we need to deconstruct the parts of our identity built on the graves of others. It’s not easy.


Jefferson's gentleman farmer was the forerunner of the people who populate the gentrified Charlottesville that exists today of expensive coffee-shops and celebrity-filled suburbs. This romantic idea, much like the lifestyles of the American and English elite today, seems to engender a lot of resentment from those who can only watch helplessly, and are often gentrified out. It’s not only immigrants or, in the United States, African-Americans, who are denied access to America's Williamsburgs and Charlottesvilles, London's Shoreditches and Oxfords. In Charlottesville, descendants of white sharecroppers and black slaves alike are unable to afford $15 glasses of local Virginia wine.

The paradox implicit in Jefferson’s beautiful idea is that in the end, it’s impossible to sustain this chilled-out and happy lifestyle without the labor being done by others, be they slaves, sharecroppers, or factory workers in China. If America is in trouble now, the conflict comes precisely from the fact that our universalist ideas of freedom, equality, and liberty correspond to an economy that is anything but universal. We actually did it, keep doing it, and unless we can use these ridiculous men dancing through our streets iin Halloween costumes as a funhouse mirror to make us see ourselves as we are, we’ll probably keep doing it.

I resent Jefferson for his hypocrisy, because in truth, I would love it if America looked more like Charlottesville than the industrialized and nasty-looking Interstate 95 highway that leads up the East Coast, the aftermath of Hamiltonian industrial-revolution factory America. The New Jersey towns, the gas stations, what we contemptuously call “McMansions,” suburban Northern Virginia... none of it is really authentic enough. Parallel to the rich and ugly suburbs, are poor and ugly towns, the sort of places with unemployment and discounts on cereal that tastes like sugary trash in the supermarket.

The residents of these towns don’t hate the residents of more gentrified towns for our organic granola, they hate the world for the structures of oppression that they can’t escape, even as an international class, an educated class, a well-meaning class, escapes without even needing to. We coexisted in the same place but not the same set of opportunities, and we glided on to new and bigger worlds of possibility, ones denied to those of different class backgrounds, regardless of their ethnicity.


Some of my African-American classmates at Charlottesville High School were likely descendants of Jefferson’s slaves, coming from poorer neighbourhoods and housing projects and taking "standard" level classes, with honors and AP classes for students whose parents worked in the University (very liberal, of course), a genteel place where every year, some kid wears blackface or a Nazi outfit to a party - as a joke, of course. While my classmates in AP and Honors classes got help from our teachers in applying to Ivy League schools, the general level classes saw black and white students who shared poorer backgrounds acting out to get attention from harried teachers. This was public school, but Charlottesville’s many excellent private schools, of course, didn’t even have the general level students at all.

Despite some southerners such as Lee supporting the post-war “reconstruction,” white resistance to racial equality led to a Jim Crow system that wasn’t much better than slavery, and an American South which dozed in sweaty decline while the rest of the country industrialised and modernized. From 1865 to 1965, not much happened in the South. True, there were intellectual movements like the Agrarians, whose 1920s manifesto “I’ll Take My Stand” I found one high school afternoon in the local bookstore, we had our Faulkners, our occasional geniuses. But as a society, it was stagnant. 

It was only when the civil rights movement began that the south began to actually rise again. UVa went from being a minor regional school to being a world-class one. Charlottesville went from being a mediocre gentleman’s club to a place that people of all backgrounds could make lives for themselves in the public service. And we, the public, gained so much - that’s why my family chose to live there.

I remember as a child strolling the beautiful downtown mall to go to dinner al fresco with my parents, my father pointed out a man in a turban; it was Satyendra Huja, a Sikh professor at the university who had planned the downtown mall, and made a useless street into one of the nicest places to congregate in town. In 2012, Huja became the mayor. I guess the former mayor of Charlottesville who single-handedly made Charlottesville one of the most charming towns in the country often gets told to “go home,” as if that's somewhere else.

Martin Luther King Jr.’s birthday is a national holiday in the United States, but in Virginia it used to be “Lee/King/Jackson” day, with two confederate officers added in just as a reminder. That’s not really our heritage, and as students, we were grateful for the day but always laughed at how immature it was that the powers that be needed to block out Dr. King’s achievements so much.


Charlottesville is a southern town true to and even obsessed with our heritage - a place filled with museums, historians, bookstores - which wants to dissect that heritage to remove the parts of our forefathers (and mothers) lives that we can’t accept, like a sandwich that you open up, take the pickles out of, and then keep on eating. We love our heritage in Virginia. We read about it, celebrate it, live it every day. But heritage isn’t a static thing, fixed in time, and the walls between myth and history are thin. In fact, perhaps knowing about your heritage is the ultimate form of privilege. I doubt that either the descendants of slaves I went to high school  with, or the “redneck” (so-called because they got sunburned by working in the fields - “redneck” is a class slur) descendants of the illiterate sharecroppers of rural Maryland, do. 

What happened this weekend to Charlottesville could happen to any town as long as we those who are deprived of their history and who don’t feel at home in their hometown. But the Charlottesville I remember, and the one it is now, proves that you can go from war and conflict and institutionalised racism to one where people of all races and identities can coexist, for the most part, peacefully and happily. We can, if we try, honor Jefferson for his achievements without forgetting the slaves his beautiful buildings were built by. A “Memorial to Enslaved Laborers” is being built on the campus he founded.

For the first time, every one of my old friends is thinking about racism, white privilege, the origins of violence, and what we can do about it. We can honor Jefferson and General Lee’s memory best by trying to learn from their mistakes. Maybe, if it seems like we are able to solve these problems, I’ll have a child myself. I hope she goes to Venable Elementary School, and I’ll take her to Emancipation Park afterwards.
