What happens when a life-saving cure is discovered, and then given away for a single dollar?

In this Tribulations episode, Dr. Ravi Kumar tells the remarkable story of Frederick Banting, the farm boy turned surgeon whose late-night idea led to the discovery of a method for extracting insulin and saved millions of lives. You’ll travel from the starvation wards of the early 1900s to the sweltering attic lab in Toronto where Banting and Charles Best performed the experiments that changed medicine forever. Dr. Kumar also explores the moral and policy issues that continue to shape insulin access today.

In this episode, you’ll discover:
 • How diabetes went from a fatal disease to a manageable condition.
 • The late-night inspiration that drove Banting to isolate insulin.
 • The brutal experiments and the first successful treatment in a dying child.
 • Why Banting sold the patent for one dollar, and what that decision means today.
 • How insulin’s legacy has been both a triumph of compassion and a failure of modern medicine.

Key Takeaways
 • Before insulin, type 1 diabetes was a death sentence; starvation diets only delayed the inevitable.
 • Banting’s insight to tie off the pancreatic ducts allowed insulin to be isolated intact.
 • His team’s discovery turned childhood diabetes from a fatal disease into a chronic, livable one.
 • Banting gave away the patent to keep insulin affordable, but modern pricing has drifted far from his vision.
 • The story of insulin reminds us that compassion, not commerce, should guide medical innovation.
