What happens when a country doctor risks the life of an eight-year-old boy in the hope of defeating humanity’s deadliest disease? In 1796, Dr. Edward Jenner carried out a bold and deeply controversial experiment: infecting the gardener’s son, James Phipps, with cowpox to see if it would protect him against smallpox. It succeeded—and marked the birth of vaccination. But at the same time, it raised profound ethical questions that still echo today.

In this episode of Tribulations, Dr. Ravi Kumar guides us through the tension between discovery and morality. You’ll explore:

• How smallpox shaped civilizations, toppled empires, and even served as biological warfare
• The global practice of variolation, including how Lady Mary Wortley Montague helped bring it to Europe, despite the serious risks involved
• Jenner’s defining experiment on James Phipps and the scrutiny it might attract under today’s ethical standards
• The early resistance and skepticism that greeted vaccination, and how history’s first demonstrable medical breakthroughs stirred fear before acceptance
• How the dangers of vaccines rare complications like Guillain-Barré syndrome must be weighed against the overwhelming benefits they deliver

It’s a captivating journey of risk, impact, and the ethical tightrope of progress.

How to Make Gout Disappear From Your Life

What if one of the most excruciatingly painful diseases in history — once called “the disease of kings” — didn’t have to exist at all? Gout, an inflammatory arthritis caused by uric acid crystals, has plagued everyone from Henry VIII to Benjamin Franklin. Yet today, science shows us it can often be prevented — or even eliminated — with the right knowledge and choices.

In this eye-opening episode, Dr. Ravi Kumar unpacks the history, biology, and modern causes of gout — and reveals why this ancient disease is now a completely optional one. You’ll hear how gout uniquely affects humans, why certain populations are more vulnerable, and even the story of a dramatic case where gout crystals formed in a woman’s brainstem.

In this episode, you’ll discover:

• Why humans are the only species that develop gout.
• The historical link between gout, indulgence, and power.
• How modern diets rich in purines, alcohol, and fructose fuel the disease.
• The surprising roles of coffee, vitamin C, cherries, and dairy in lowering risk.
• Why keeping uric acid below 6.0 mg/dL protects against gout and kidney damage.
• How simple lifestyle changes can make gout vanish from your life.

Don’t miss this episode — especially if you or someone you love struggles with gout. Understanding its history and science could help you prevent or reverse it.

*** Correction: In this podcast I said that humans are the only species to get gout, but I should have said humans are the only mammalian species that get gout. Both birds and reptiles can develop uric acid crystallization within their bodies when they are severely dehydrated or have kidney failure.

What happens when a children’s book author refuses to accept “good enough” in the face of a life-or-death medical crisis? In 1960, Roald Dahl, famed author of Charlie and the Chocolate Factory, found himself fighting for his infant son’s life after a devastating accident caused hydrocephalus, a dangerous buildup of fluid in the brain.

In an era when shunt valves failed constantly, Dahl brought together an unlikely team: a pioneering pediatric neurosurgeon, a pediatric brain surgeon, and a retired toy maker. Together, they created the WDT valve, a life-saving device that resisted clogging and became a gold standard in treating hydrocephalus.

In this episode of Tribulations, Dr. Ravi Kumar takes you through the gripping history of how creativity, persistence, and cross-disciplinary collaboration changed the course of neurosurgery. You’ll learn:

• The accident that nearly claimed Dahl’s son’s life
• Why existing shunts in the 1960s were dangerously unreliable
• How Dahl’s relentless curiosity pushed doctors to imagine the impossible
• The ingenious engineering behind the WDT valve
• How this invention saved thousands of children, and still influences shunt design today

It’s a story of ingenuity under pressure, of refusing to accept the limits of conventional thinking, and of how one man’s persistence turned imagination into innovation.
