Sterile fly maggots are an FDA-approved medical device. They eat only dead tissue and secrete compounds that clean wounds and kill drug-resistant bacteria. Where antibiotics fail against chronic infections, maggot therapy can work. The FDA cleared it in 2004.

In 1984, Barry Marshall drank Helicobacter pylori culture to prove bacteria caused stomach ulcers after medicine dismissed the idea. He developed gastritis within days, cured himself with antibiotics, and shared the 2005 Nobel Prize in Physiology or Medicine with Robin Warren.

In a 2010 Harvard study, IBS patients handed pills labelled "Placebo — inert ingredients" still improved significantly more than untreated patients. The brain responds to the ritual of swallowing a pill even without deception — triggering real neurochemical changes.

Textbooks taught for decades that bacteria outnumber human cells 10 to 1 — a 1972 rough estimate cited without scrutiny. A 2016 Weizmann study found about 38 trillion gut microbes vs. 30 trillion human cells: 1.3 to 1, not 10 to 1. The number was inflated tenfold.

Acetaminophen (Tylenol) may relieve social rejection as well as headaches. A 2010 study found three weeks of daily use made social exclusion less distressing, with brain scans showing reduced activity in the same nerve circuits that handle physical pain.

Bears lose almost no muscle during nearly six months of hibernation. Humans can shed 20–30% of muscle after two weeks of bed rest. A *Science* study found gut bacteria recycle waste urea into amino acids for muscle protein; NASA studies the idea for long spaceflight.

USA physician Samuel Cartwright announced a fake mental illness in 1851 supposedly afflicting only Black slaves: "Drapetomania." Symptom: "the urge to flee the plantation." Cures: whipping and amputating big toes. The term remained in Stedman's Medical Dictionary until 1914.

The claim that the Caesarean section is named after Julius Caesar's birth is almost certainly false—his mother lived for decades after his birth, and no woman could have survived the procedure with the medicine of that era.

Hypodermic injection needles aren't made by drilling holes. A flat steel strip is rolled into a tube, welded, then pulled through progressively smaller holes. Larger gauge numbers mean thinner needles — 18G means the wire passed through 18 holes.

The fact that scurvy can be prevented with citrus fruits was known as early as the 1400s. Yet humanity kept rediscovering and forgetting this cure for over 400 years. Mainstream medicine did not fully accept it until 1907.

The barbershop pole originated from a time when barbers in Europe also performed surgery. Red represents arteries and bleeding, blue represents veins and shaving, and white represents bones and bandages.
