Friedrich Nietzsche once quipped, “To see others suffer does one good.” When it comes to the world of live theatre, that unsettling thrill of watching a production go off the rails can be oddly captivating. In this roundup we explore ten unforgettable moments when the curtain rose on chaos, reminding us that anything can happen when actors, sets, and technology share the same stage.

Why 10 Times Live Theatre Blunders Still Captivate Audiences

Unlike movies or TV shows, where every stumble can be edited out, live performances are raw, unfiltered, and prone to surprising mishaps. From broken props to literal fires, each incident below shows how a night at the theatre can quickly become a lesson in improvisation—and sometimes, a comedy of errors.

10. Mamma Mia!

Mamma Mia!—the ever‑cheerful ABBA‑filled musical—generally promises a feel‑good evening. Yet in 2014, a London audience member got more than a sing‑along when the hair‑dryer Kim Ismay used as a microphone prop malfunctioned. The cable snapped mid‑song, sending the dryer flying straight into the crowd and striking an unsuspecting patron squarely in the face.

As an apology, the theatre offered the victim a glass of champagne during intermission, hoping the bubbly would soften the shock of the unexpected hair‑dryer assault.

9. Titanic

Staging a musical about the world‑renowned maritime tragedy seemed daring enough, but the 1997 Broadway preview of Titanic proved the ship’s name was a foreboding omen. Before the curtain even rose, the director warned the audience of a turbulent voyage ahead, and the warning proved prophetic.

The production’s massive three‑story tilting hydraulic lift kept jamming, forcing the show to grind to a halt repeatedly. To keep spirits up, a cast member entertained the crowd with jokes while technicians wrestled with the faulty set. In the end, the performance stretched to three and a half exhausting hours—an hour longer than the real Titanic’s fateful sinking.

9. The Queen of Spades

In 2002, opera singer Susan Chilcott demonstrated true dedication when a stray candle ignited the train of her gown during a performance of Tchaikovsky’s The Queen of Spades. Unaware of the blaze, she continued her aria while audience members shouted warnings.

A fire officer eventually rushed onto the stage to douse the flames, startling the prima donna who initially thought an intruder had entered the Royal Opera House.

7. Way Upstream

Alan Ayckbourn’s 1982 production of Way Upstream took “immersive theatre” to a literal level, flooding the National Theatre’s stage with a boat set floating in eight inches of water. Ayckbourn warned patrons they might need Wellington boots, and the warning proved wise.

Technical rehearsals went awry when the water tank burst, threatening the venue’s electrical system and damaging the floor by £3,000. The opening night began late, only to be cut short mid‑act when the boat collided with the riverbank.

After an 18‑minute pause to repair the damage, the show resumed, but a 12‑minute rain effect drenched the front‑row stalls, leaving audience members thoroughly soaked.

6. Macbeth

The Scottish play’s reputation for curses dates back to a 1606 production where a coven of witches allegedly hexed the drama. Over the centuries, countless mishaps have plagued performances, cementing its ominous legacy.

In a 1672 Amsterdam staging, the director chose to depict King Duncan’s murder onstage. Amid a heated rivalry, the actor playing Macbeth swapped a prop dagger for a real one, delivering a fatal thrust that killed the King‑playing actor instantly.

A similar tragedy unfolded in London the same year when Henry Harris, portraying Macduff, accidentally drove his sword through Macbeth’s eye, ending the performance with a literal “eye‑popping” finale.

5. Henry VIII: All Is True

Shakespeare’s historical epic Henry VIII: All Is True met disaster on 29 June 1613 when a cannon meant to dramatize King Henry’s meeting with Anne Boleyn misfired. The blast ignited the Globe Theatre’s thatched roof, sending flames racing through the wooden structure.

Within an hour, the entire theatre was reduced to ashes. Remarkably, only one casualty was reported—a gentleman whose breeches caught fire, which he extinguished by dousing himself in copious amounts of ale.

4. The Curious Incident of the Dog in the Nighttime

In December 2013, London’s Apollo Theatre suffered a structural failure during a sold‑out performance of The Curious Incident of the Dog in the Nighttime. Mid‑show, a balcony gave way, sending a cascade of debris onto the audience.

Initially, many patrons assumed the cracking sounds and falling plaster were part of the production’s design. However, the arrival of 25 ambulances made it clear the spectacle had turned into a genuine emergency, though, thankfully, no lives were lost.

3. The Full Monty

The Manchester Opera House’s September 2014 run of The Full Monty promised a cheeky finale where steelworkers strip down to their underwear, hidden by a blinding light before a blackout. Unfortunately, a lighting glitch left the audience-facing lights dead.

Consequently, the male cast was fully exposed, baring more than just their talent, to a shocked—and perhaps delighted—crowd. The moment perfectly embodied the show’s slogan, “You can leave your hat on!”

2. Wicked

Even Broadway’s most iconic productions aren’t immune to mishaps. On 8 January 2005, Idina Menzel’s iconic “melting” scene in Wicked went sideways when the hidden elevator beneath the trap door descended prematurely.

Without Menzel in place, she fell through the opening, cracking a rib. The performance halted, and her understudy stepped in for the remainder of the show and the rest of the run.

1. Spider‑Man: Turn Off the Dark

What could possibly go wrong with a Broadway musical that lets actors swing from webs high above the stage? The notorious Spider‑Man: Turn Off the Dark proved that even superhero spectacles can crash spectacularly.

During a preview, a backstage mishap caused a carabiner to drop onto an actress’s head, giving her a concussion. Yet the real drama unfolded just before intermission when the lead’s aerial cable snapped, leaving him dangling seven feet above the front rows.

Unable to reach him, the crew resorted to poking the suspended actor with sticks, turning the scene into a bizarre, real‑life Spider‑Man piñata. The show was forced to stop, cementing its place in theatrical infamy.

When brands slip their logos into movies, TV shows, or viral videos, they hope for a quiet boost that turns viewers into shoppers. In theory, product placement should be a masterstroke of subtle persuasion—just enough exposure to make a product feel like a natural part of the story. In practice, however, the gamble can backfire spectacularly, turning a clever cameo into a public relations nightmare. Below we dive into ten notorious moments where “10 times product” placement missed the mark, leaving brands bruised, audiences cringing, and marketers scrambling for damage control.

From candy that unintentionally stole the spotlight from a rival, to a beer brand that forced James Bond to abandon his beloved martini, these case studies prove that even the biggest budgets can’t buy authenticity. Each entry shows how tone‑deafness, over‑exposure, or sheer bad luck turned a promising partnership into a cautionary tale for anyone hoping to hitch their name to Hollywood glitter.

10 Times Product Placement Mishaps

10 Reese’s Pieces: E.T. Almost Went to M&Ms

Most people recall how E.T. turned Reese’s Pieces into an instant bestseller, catapulting sales by more than 65% after the alien lured the candy‑loving kids out of hiding. What’s less known is that Hershey wasn’t the first choice. Mars, the maker of M&Ms, was originally offered the spot but declined, fearing that an eerie extraterrestrial could scare children and tarnish the brand’s clean, family‑friendly image. Executives worried that aligning M&Ms with a “weird‑looking creature” would clash with their wholesome reputation.

By passing on the opportunity, Mars inadvertently handed Hershey a golden ticket. Hershey not only supplied the candy but also poured a $1 million promotional push into the film’s marketing. The result? Reese’s Pieces vaulted to household‑name status overnight, while Mars watched in hindsight as its rival outsold M&Ms for the first time ever immediately after the movie’s debut. The missed chance still haunts Mars executives, who reportedly reminisce about the lost revenue each time they see a Reese’s bag on a store shelf.

9 Heineken: James Bond Ditches the Martini

When Skyfall hit theaters in 2012, fans were shocked to see 007 swapping his signature shaken‑not‑stirred martini for a cold Heineken. The switch wasn’t a creative decision—it was a $45 million sponsorship deal woven into the film’s $200 million budget. Hardcore Bond devotees erupted online, branding the move a betrayal of the spy’s timeless sophistication and accusing the franchise of selling out to corporate interests.

Even Daniel Craig, playing Bond, awkwardly defended the choice in interviews, bluntly stating that without the Heineken partnership, “We wouldn’t have been able to afford to make the movie.” While Heineken enjoyed massive global exposure, the overt placement alienated many longtime fans, spawning memes, jokes, and think‑pieces about “Brand 007.” For a series built on effortless cool, the forced product tie‑in felt clunky and diluted Bond’s iconic mystique.

8 Pepsi: Kendall Jenner Protest Ad

In 2017 Pepsi launched a commercial that tried to ride the wave of social‑justice activism, featuring Kendall Jenner diffusing a tense protest by handing a police officer a can of Pepsi. Instead of applause, the ad ignited a firestorm of criticism. Viewers accused Pepsi of trivializing real struggles such as Black Lives Matter, reducing profound civil‑rights battles to a cheap, feel‑good marketing stunt. Social media users quickly juxtaposed the staged scene with authentic protest footage, highlighting the stark contrast.

The backlash forced Pepsi to pull the ad within 24 hours and issue a public apology to both viewers and Jenner, who herself faced intense scrutiny. The incident became a viral emblem of tone‑deaf corporate messaging, illustrating how brands can appear disconnected when they co‑opt serious issues without genuine consultation. Pepsi later admitted it hadn’t engaged any real activists or organizations during the ad’s creation, turning a supposed “empowering” moment into a textbook example of mis‑firing a social‑cause campaign.

7 Chrysler: The Italian Job (2003)

The 2003 remake of The Italian Job is famous for its high‑octane Mini Cooper chase scenes, but the original plan almost featured Chrysler’s lineup. Chrysler had negotiated a product‑placement deal, filming scenes with the Neon and PT Cruiser, hoping to capitalize on the film’s high‑profile release and capture a younger demographic. A full promotional campaign was slated around the movie, banking on the heist’s visual appeal to boost sales.

At the eleventh hour, BMW swooped in with a more enticing offer, supplying Mini Coopers and additional promotional support. The filmmakers quickly realized the compact, zippy Minis were far more cinematic than the bulkier Chryslers. Chrysler’s footage was scrapped, their marketing materials had to be reworked, and the brand vanished from a film that propelled Mini Cooper sales by over 20%. In the end, Chrysler spent millions on a placement that left them looking like they’d missed the race before it even started.

6 Starbucks: Game of Thrones Coffee Cup Fail

During the 2019 final season of Game of Thrones, eagle‑eyed fans spotted a modern coffee cup perched on a table in a medieval‑style setting. The internet erupted with jokes about “Daenerys ordering a pumpkin‑spice latte.” Although the cup wasn’t an intentional placement, marketing analysts estimated Starbucks inadvertently received $2.3 billion worth of free advertising. Fans even crafted fake promos suggesting Starbucks had “won” Westeros.

The mishap highlighted a production slip‑up: HBO’s oversight made the show look careless, tarnishing its reputation for meticulous world‑building. While the cup wasn’t actually a Starbucks product—originating from a local craft‑services vendor—the damage was done. Viewers’ immersion was broken, and the final season became synonymous with bloopers and rushed editing, with the coffee cup symbolizing how far the epic had fallen from its earlier, detail‑obsessed glory.

5 Subway: Community’s Awkward Human Mascot

In a 2012 episode of NBC’s Community, Subway paid for in‑show product placement, but instead of a brief cameo the writers introduced a character who legally changed his name to “Subway” to satisfy Greendale’s sponsorship requirements. This human mascot became a love‑interest and subplot, treated half‑seriously and half‑mockingly, turning the brand into a slightly unsettling, living advertisement.

While the show’s fanbase praised the sharp satire, Subway’s corporate offices reportedly felt uneasy when they realized the brand was being lampooned rather than glorified. Executives had envisioned a cool, hip integration, but the episode rendered Subway as a cringe‑worthy figure. Some reports claim Subway tried to exert creative control after the episode aired, but the damage was already done—its brand became forever linked with an odd, human mascot rather than the sleek sandwich chain image it sought.

4 Pizza Hut: Wayne’s World’s Over‑the‑Top Satire

Wayne’s World (1992) is remembered for its tongue‑in‑cheek mockery of product placement, where the protagonists break the fourth wall to endorse Pizza Hut, Pepsi, Doritos, Reebok, and Nuprin in exaggerated, robotic tones. What seemed like harmless parody turned into a sting for the companies involved. Pizza Hut, in particular, expected a sleek cameo that aligned with youth culture, not a caricature of soulless consumerism.

Executives reportedly pushed for edits during post‑production, but the scenes remained. The film’s massive success amplified the jokes, creating a cultural backlash against overt product placement for years to come. Instead of subtle buzz, Pizza Hut was blasted as a laughably corporate entity, its brand portrayed as the epitome of a shallow advertisement. Ironically, the movie cemented its place in pop culture precisely because it mocked what Pizza Hut believed it was buying into, leaving the chain looking like a punchline.

3 Nike: The Wizard (1989)

The Wizard functioned largely as an extended advertisement for Nintendo, masquerading as a family road‑trip movie that culminated in the reveal of Super Mario Bros. 3. Nike signed on for a sizable product‑placement deal, supplying sneakers for the main characters in hopes of tapping into the film’s anticipated teen‑market appeal. Unfortunately, the movie bombed critically, and the forced brand tie‑ins became a focal point of the backlash.

Critics dismissed the film as a shameless corporate cash grab, and Nike’s branding suffered collateral damage. Rather than appearing trendy or athletic, the brand seemed pandering and over‑commercialized, alienating both audiences and reviewers. While Nintendo survived thanks to its robust gaming empire, Nike’s involvement served as a cautionary example within marketing circles: never bet your brand’s image on a project you don’t control.

2 Sony Products: I, Robot (2004)

I, Robot was littered with conspicuous Sony product placement: Will Smith’s 2004 Converse sneakers, his Sony Ericsson phone, and futuristic Audi cars—each lingering on screen long enough to feel like a commercial break. Rather than enhancing the film’s sleek, futuristic vibe, these blatant placements anchored the movie in early‑2000s branding, making the world feel dated instead of cutting‑edge.

Sony aimed to associate its products with a high‑tech future, projecting an image of stylish technology dominating everyday life. Instead, audiences perceived the film as a giant advertisement, breaking immersion during crucial story moments. The placement was widely mocked online and in reviews, reinforcing the notion that heavy‑handed corporate sponsorship can undermine storytelling when not handled with subtlety.

1 Coke: American Idol’s Aggressive Cups

During the early seasons of American Idol, Coca‑Cola invested over $30 million for product placement, plastering giant red Coke cups on the judges’ desks. The cups appeared in nearly every shot—stage performances, backstage rehearsals, and promotional material—making the branding impossible to ignore. Viewers joked that the real judges were Simon, Paula, Randy, and Coke.

The saturation turned Coke into a symbol of marketing overload. Late‑night comedians riffed on the constant red‑cup presence, and loyal fans began to complain that they were being “beaten over the head” with corporate sponsorship. While Coke’s visibility was undeniable, the omnipresent branding crossed into parody, turning what should have been positive exposure into an ongoing internet joke.

When we talk about 10 disease theories that once guided medical practice, we enter a world of imagination gone awry. From ancient Egypt to 17th‑century alchemy, brilliant minds built elaborate explanations for illness—often with spectacularly wrong results. Below, we rank these misguided notions from the most bizarre to the surprisingly influential.

10 disease theories that fooled the world

10 Female Hysteria

Scientists once used pseudoscience as a means of correcting hysteria in women. The theory dates back to ancient Egypt. Many great thinkers imagined that hysteria was brought about by the position of the uterus (aka “the wandering womb”).

The word “hysteria” is derived from the Latin hystericus (“of the womb”). Smelly substances were often placed near the vagina to correct the problem. The ancient Greek physician Aretaeus thought the womb was repelled and attracted to different fragrances. The scent of the substance used depended on whether the uterus was high or low.

The medical fraternity’s understanding of hysteria turned stranger still. According to Greek mythology, the priest Melampus was said to have rid Argo’s virgins of their strange behavior. The daughters of King Proetus went mad and hallucinated that they were wandering cows. Melampus cured the women with roots of the flower hellebore and instructed them to make love to virile men.

And so the notion of a “melancholy uterus” came to pass. Prominent thinkers, like Plato and Hippocrates, believed the female uterus had its own moods. Lack of sex and reproduction were thought to make the uterus sad. An unhappy uterus, argued Hippocrates, was ultimately caused by a buildup of poisonous humors. These humors then migrated to other parts of the body and caused disease. Similar theories persisted from ancient Rome onward.

According to US scholar Rachel Maines, theories surrounding hysteria led to the invention of the vibrator. In the 19th century, doctors were tasked with pleasuring women into a state of normality. It is said that doctors, bored with giving manual hand jobs, passed the responsibility on to midwives. (Other scholars disagree with Maines’s hypothesis.)

The electromechanical vibrator was originally invented in the late 1800s to massage muscles. Medical doctors decided it would be quicker to use the device to give women “hysterical paroxysms” (i.e., orgasms). Treatment times were slashed from around an hour to just 10 minutes.

9 Trepanning And Evil Spirits

Today, the practice of drilling a hole in one’s head to treat mental health problems is a tough sell. But that was not always the case. From Neolithic times to ancient Greece, numerous civilizations used a procedure called trepanation to combat disease. Trepanation involves making a hole in the human skull to remedy some perceived ailment.

During Paleolithic times, primitive tribes used trepanation to expel evil spirits from the body. In reality, the symptoms witnessed probably stemmed from mental illness. Skull fragments from the operation were highly sought after. Shamans would fashion amulets from the fragments in the hopes of fending off demonic possession.

The warring tribes of South America put the procedure to slightly better use. They used trepanation to treat traumatic head injuries. Today, modern surgeons use a refined form of trepanation to alleviate intracranial pressure. So perhaps there was some method to their madness.

Even now, a few brave souls use trepanning techniques to alter the flow of blood and cerebrospinal fluid in their heads. (N.B.: Do not try this at home unless you enjoyed the ending to One Flew Over the Cuckoo’s Nest.)

Amanda Feilding, founder of the Beckley Foundation, performed self‑trepanation in the early 1970s. She believes that “stagnant pools” of toxins contribute to diseases like Alzheimer’s. Feilding ran for parliament in the UK twice on a platform of providing “Trepanation for the National Health.” She received few votes.

8 The Elixir Of Life

They say two things are certain in life: death and taxes. But it seems that the elites of ancient China were obsessed with avoiding the former. In a bid to find the elusive “elixir of life,” they put their faith in alchemists. Over 2,000 years ago, the very first emperor of unified China, Qin Shi Huang, ordered his men to find a potion that would make him immortal.

In what can only be described as an epic miscalculation, alchemists gave the emperor his elixir: mercury. As we now know, mercury only serves to bring about the recipient’s speedy demise. Historians believe the emperor was poisoned after consuming an unhealthy dose of mercury sulfide. He died at the not‑so‑immortal age of 49. Despite this obvious failure, alchemists continued their work. Many of them died toiling over their elixirs.

Before his passing, Qin Shi Huang ordered the creation of his Terracotta Army. These inanimate warriors were placed in the emperor’s enormous burial chamber to protect him in the afterlife. Ironically, archaeologists think Qin Shi Huang’s tomb is surrounded by a river of mercury.

Qin Shi Huang was not the only emperor to succumb to the temptation of quicksilver. Emperor Xuanzong of Tang was given an elixir derived from a mercury ore (cinnabar). He developed classic symptoms of mercury poisoning, including itching, muscle weakness, and paranoia.

The alchemists argued that these symptoms were a mere blip on the road to immortality. Of course, the emperor died shortly after. A number of Xuanzong’s predecessors died taking similar elixirs, including emperors Muzong and Wuzong. Emperor Muzong suspected something was up, so he made his alchemists consume their own poisonous concoctions. Muzong’s wisdom did not last long. He, too, became obsessed with elixirs and poisoned himself.

7 Miasma Theory

The miasma theory was proposed to explain the spread of disease. Before the germ theory came to pass, scientists thought that atmospheric impurities (“miasmata”) were the primary cause of disease. Plague doctors were illustrative of this theory in action. These frightening characters wore beak‑shaped masks that were designed to keep foul‑smelling miasmata away. The masks were packed with aromatic herbs to stop doctors from inhaling “bad air.”

In Victorian England, Edwin Chadwick put forward the miasma theory to explain London’s cholera epidemics. Meanwhile, Florence Nightingale argued that outbreaks of measles, smallpox, and scarlet fever were caused by building houses too close to smelly drains.

An anesthetist called John Snow refuted the miasma theory. Snow said that cholera was transmitted via polluted water, not bad air. This was a controversial hypothesis for the time.

Snow observed that certain parts of London were more likely to experience cholera outbreaks than others. He realized that some of the local water companies filtered and purified their water, while others did not. All the companies took their water from the Thames—a swirling cesspit of refuse, effluent, and general despair. (Some things never change.)

Regions with high levels of cholera often received unpurified water from especially dirty parts of the Thames. Snow also discovered a link between the spread of waterborne diseases and the city’s inadequate sewage system. One major outbreak was caused by a cholera‑riddled diaper that had been dumped in a leaky cesspit. The disease took hold when water from the cesspit contaminated a nearby water pump.

In 1861, Louis Pasteur’s germ theory proved that Snow was correct. The discovery of the bacterium Vibrio cholerae was the final piece of the puzzle. The miasma theory, which dated back to the time of Hippocrates, was finally put out to pasture.

6 Tooth‑worm

Dental caries are no joke. This was especially true in Babylonian times when the Legend of the Tooth‑worm existed. Thereafter, a number of ancient civilizations thought that wriggly worms were responsible for cavity‑related pain.

The theory goes that a nasty worm would bury itself in the tooth. Its wild movements inflicted great pain on the sufferer. Only once the worm tired and ceased its thrashing would the pain subside. Some civilizations thought the creature was actually a demon taking on the guise of a worm.

Fumigations and extractions were popular treatments for tooth‑worm. Scribonius Largus, the physician to the Roman emperor Claudius, performed fumigations with henbane seeds. It was said that the resultant fumes would repulse the pest. During the 17th century, a number of charlatans conned patients into thinking they had tooth‑worm. The practitioners would only pretend to extract worms. In reality, they were simply removing pieces of lute string.

Roman philosopher Pliny the Elder is worth a brief mention. Pliny’s cure for toothache involved capturing a frog by moonlight, spitting in its mouth, and saying, “Frog, go, and take my toothache with thee!”

In 1728, Pierre Fauchard published a two‑volume book, The Surgical Dentist. Described as the “father of modern dentistry,” Fauchard debunked the theory of tooth‑worm and recommended that patients reduce their sugar intake.

5 Ulcers And Stress

Until recently, practitioners and researchers were united in their belief that ulcers were caused by stress and excess stomach acid. Scientists who were skeptical of this entrenched theory were the subject of ridicule.

So, in 1984, Barry Marshall set out to make a point. The Australian gastroenterologist was convinced that ulcers were the result of a bacterium called Helicobacter pylori. He was so convinced that he started experimenting on himself.

His colleague cooked up a delicious broth of H. pylori, which Marshall then drank. Now a miserable vomit‑sprinkler, Marshall was diagnosed with acute gastritis. He cured himself with a simple course of antibiotics. The theory behind stress‑induced ulcers was beginning to crumble.

However, Marshall and his colleagues faced considerable pushback from the medical‑industrial complex. A number of big drug companies were worried that antibiotics would make their products redundant. “Because the makers of H2 blockers funded much of the ulcer research at the time, all they had to do was ignore the Helicobacter discovery,” explained Marshall.

For the longest time, the idea that bacteria could survive in such an acidic environment was laughable. But scientists soon discovered that Helicobacter could effectively neutralize the acid around it.

Researchers now think that 80 percent of gastric ulcers are caused by the bacterium. Barry Marshall and colleague Robin Warren won a Nobel Prize for proving their peers totally wrong.

4 Corpse Medicine

Corpse medicine was the practice of using human corpses to treat illness. The part of the body consumed was dependent upon the ailment. “Like cures like,” argued the homeopaths. Therefore, nosebleeds and epilepsy were often treated with bits of skull, while superficial wounds were wrapped in fat‑soaked bandages.

Europe’s rich and famous were pigging out on human bodies during the 16th and 17th centuries. The continent was rife with cannibalistic gravediggers looking for a quick buck. Egyptian tombs were looted of their mummified inhabitants and used to treat bruises and bleeds.

Even royalty was at it. England’s King Charles II was partial to a little alcohol and ground skull (aka “The King’s Drops”). The king would tootle off to his own laboratory and brew up a batch himself.

Another form of corpse medicine was seen in 19th‑century Denmark. Public executions were attended by blood‑lusting spectators, many of whom brought their own cups.

In 1823, Hans Christian Andersen described witnessing a man feed the blood of an executed felon to a child. The blood was used as a treatment for epilepsy. Blood was referred to as the “elixir of life” throughout the Middle Ages (marginally better than mercury), and virgin blood was used to cure leprosy.

This “medical vampirism” dates back to ancient Rome. Numerous civilizations thought that human blood carried the soul. Drinking blood, they theorized, could stave off illness and afford new strength. It was this mystical belief that compelled the Romans to drink the blood of gladiators killed in the arena.

3 The Four Humors

Knowledge of anatomy and medicine soared under the physicians of ancient Greece. Dissections and vivisections provided doctors with fresh insight into the body’s inner workings.

Galen found that the brain controlled movement via nerves. Herophilus distinguished between veins and arteries. A number of prominent philosophers drew a connection between disease and the environment. And a biological trigger of disease replaced the supernatural. However, one deeply flawed theory went uncontested: the four humors.

Ancient Greek medicine was heavily influenced by Hippocrates. His theory on humoralism supposed that the body was made up of four fluids: blood, phlegm, black bile, and yellow bile. An imbalance in these fluids, or humors, would lead to disease. The four humors were also associated with an individual’s mental state. For example, a patient was melancholic if he had too much black bile.

But where did the idea of these humors come from? Well, the ancient Greeks were likely pouring blood samples into glass containers and leaving them to coagulate. After some time, this sample would separate into four distinct layers: red, white, black, and yellow. This is perhaps what they thought of as humors.

However, the Greeks may have taken inspiration from the four elements: earth, air, fire, and water. It was also widely accepted that these humors were somehow connected to the four seasons and planetary alignment.

Changes to diet and lifestyle were often recommended to redress the balance. The Greek physician Galen was a proponent of bloodletting to get rid of excess blood—what he considered to be the dominant humor.

Bloodletting continued under the barber‑surgeons of medieval Europe who thought the practice could cure smallpox and epilepsy. Humoralism persisted throughout the West for thousands of years. Historians suspect that George Washington’s faith in bloodletting may have contributed to his demise in 1799.

2 Urine Therapy

Simply put, urine therapy involves using urine to combat disease. Those in support of the practice extol its apparent healing qualities. Books about urine therapy wax lyrical about the “elixir of life,” “the golden fountain,” and “liquid gold.” While most qualified doctors view urine as a waste product, urine connoisseurs claim that the liquid is a distilled product of the blood (aka “gold of the blood”).

Urine has been used throughout history with alarming frequency. Thomas Vicary, Henry VIII’s surgeon, advised cleaning battle wounds with urine. The 17th‑century chemist Robert Boyle instructed patients to drink “a moderate draught of their own urine” in the morning. On the recommendation of George Thomson, urine was used to combat the deadly bacterium responsible for the Great Plague.

A quick perusal of the Internet reveals that urine therapy is something people still do today. Hundreds of thousands of people in China are said to drink urine. A surprising number of athletes have also resorted to guzzling down their own juices, including MMA fighter Luke Cummo and boxer Juan Manuel Marquez.

Madonna famously told David Letterman that urine was a cure for athlete’s foot. Some desperate teens have taken to slapping urine on their pustulous faces, while others are brewing up their own urine‑based teeth whiteners.

For obvious reasons, there remains little research on many types of urine therapy. But doctors are adamant that drinking pee is a bad idea. The practice has no health benefits and can lead to dehydration. Cleaning your wounds with urine is also a bad idea. New research shows that urine is not sterile, as was once thought to be the case.

1 Powder Of Sympathy

Sir Kenelm Digby was a man of science, philosophy, and reason. But, like many of his 17th‑century contemporaries, Digby had a keen interest in alchemy and astrology. The Englishman came up with the strange notion that applying treatments to the weapon that caused an injury would heal the wound itself.

This miracle cure was called the “powder of sympathy.” Digby’s theory was delivered to top academics at the University of Montpellier. The speech lasted two hours and boasted of endorsements from King James.

Digby’s belief in the treatment came after experimenting on his friend James Howell. The writer was wounded while trying to stop a duel in England. In this instance, the powder of sympathy was tested on Howell’s blood‑soaked bandage.

The bandage was then removed and kept separate from the wound. The treatment reportedly gave Howell “a pleasing sense of freshnesse” and a new lease on life. However, today’s scientists know better. His recovery was likely the result of good fortune and the placebo effect.

According to Digby, a Carmelite monk taught him the weapon salve. The potion was supposed to work on the basis of “sympathetic magic.” Proponents argued that a weapon would form some kind of connection to the human body after drawing blood. Digby and his colleagues believed that atoms of the lotion were attracted to the wound via some form of magnetism.

The powder of sympathy garnered considerable attention. There were 29 editions of Digby’s book, A Late Discourse … Touching the Cure of Wounds by the Powder of Sympathy. The potion was sold in many apothecaries throughout 17th‑century Europe. Even the likes of John Locke and Thomas Sydenham lauded the bizarre treatment.

Digby’s love for the supernatural did not end there. He also had a keen interest in palingenesis, a form of “biological rebirth.” He hoped that the technique would resurrect life from the crystallized ashes of plants and animals.

Some scholars suggested that Digby’s attempts at resurrection were related to an obsession he had with his dead wife, Venetia. Rumor circulated that Digby had accidentally killed Venetia by giving her large quantities of “viper wine.”
