In this episode, we explore the complex and often misunderstood world of leprosy—also known as Hansen’s disease. From its ancient roots to modern-day treatment, we break down the myths, stigma, and science behind one of history’s most feared diseases.

We dive into how leprosy was portrayed in historical and religious texts, often seen as divine punishment, and how that belief shaped centuries of isolation and mistreatment. The conversation also unpacks what the disease actually does to the body—primarily affecting the peripheral nervous system—and why its reputation as highly contagious is largely a myth.

We discuss where leprosy still exists today, the effectiveness of modern treatments, and the role of global health organizations like the World Health Organization in providing free care. Most importantly, we examine the ongoing stigma faced by those affected and why education, awareness, and compassion are essential in changing the narrative.

This episode is a powerful reminder that understanding the past—and the truth—can help us approach disease and those impacted by it with empathy rather than fear.

In this episode, we dive into the fascinating history of St. Patrick—separating myth from reality to uncover the true story behind one of Ireland’s most iconic figures. From his early life and unexpected journey into slavery, to his return as a missionary who helped shape Irish culture, St. Patrick’s legacy is far more complex than the legends suggest.

We also explore how his story evolved over time, giving rise to the global celebration of St. Patrick’s Day as we know it today.

In this episode, we dive into the strange and powerful story of ergot poisoning—from medieval epidemics to modern pharmacology. Caused by the fungus Claviceps that infects rye and other grains, ergot has triggered mass poisonings, fueled mysterious outbreaks of convulsions and hallucinations, and may even have influenced events like dancing plagues and witch trials.

But ergot isn’t just a historical curiosity. The same compounds responsible for devastating outbreaks also laid the groundwork for modern medicines used to treat migraines, control bleeding after childbirth, and manage neurological diseases.

We explore how ergot alkaloids interact with key receptors in the body—including serotonin, dopamine, and adrenergic pathways—producing powerful effects on blood vessels, the nervous system, and the brain.

You’ll also hear how ergot toxicity can still appear in modern medicine through drug interactions or overdoses, and why understanding its pharmacology remains important today.

Sometimes the line between poison and medicine is thinner than we think.
