You might find Foxglove in your garden. It’s a beautiful plant with clusters of trumpet-like flowers. It’s also a deadly poison. It’s the source of the cardiac medication digitalis that is commonly used for certain cardiac arrhythmias and a few other medical conditions.
Foxglove has been around for thousands or years and has long been known for its poisonous properties. In 1329, at the ripe old age of 38, Cangrande della Scala, the ruler of Verona, Italy, and patron of Dante Alighieri, died after complaining of gastrointestinal symptoms. These symptoms are common in cases of digitalis toxicity.
Now his exhumed body has been subjected to a more modern analysis and it seems that digitalis spores were detected in his colon. Was he poisoned with this deadly drug? Maybe, maybe not. But it is intriguing.
