At just 32 years old, Alexander the Great—one of the most formidable military leaders in history—was suddenly taken ill during a feast in Babylon. Less than two weeks later, he was dead. For over two millennia, his untimely demise has remained one of the greatest historical enigmas. Now, new academic research may offer the most plausible explanation yet: poisoning by Veratrum album, commonly known as white hellebore.
The theory, recently revived by Stanford historian Adrienne Mayor and supported by a 2014 study published in Clinical Toxicology, suggests that Alexander may have been deliberately poisoned using a slow-acting botanical toxin known to ancient healers and assassins alike. The symptoms described in historical records—including abdominal pain, vomiting, muscle weakness, and a slow, progressive decline—align closely with white hellebore poisoning.
A Deadly Feast
Alexander’s fatal illness began at a banquet—an all-night drinking party held in the sweltering heat of Babylon. According to The Royal Diary, a key ancient source, he began feeling unwell immediately after the event and grew progressively weaker over 12 days until his death. Other historical texts, such as The Alexander Romance, hint at court intrigue and suggest that he may have been poisoned by members of his inner circle.
Most poisons known to ancient societies, such as arsenic or strychnine, act rapidly—often killing within hours. That’s what makes white hellebore particularly suspicious. Unlike those quick-acting toxins, Veratrum album produces delayed symptoms that can take hours or even days to manifest. It causes nausea, intense stomach pain, a drop in blood pressure, bradycardia (slowed heart rate), and muscle paralysis—mirroring the historical accounts of Alexander’s final days.
An Ancient Weapon Hidden in Medicine
White hellebore was not an obscure plant. It was widely used in antiquity across Europe and Asia as a medicinal herb for treating conditions like epilepsy and vomiting. But in larger doses, it could become lethal. It was potent enough to cause death if ingested but subtle enough to delay suspicion—especially if added to wine, which was routinely mixed with herbal concoctions.
The 2014 study by toxicologist Dr. Leo Schep and his colleagues (Slaughter, Vale, and Wheatley) reviewed 53 historical and scientific sources to evaluate natural and unnatural causes of Alexander’s death. Their conclusion? Veratrum album is the most likely agent capable of producing a fatal illness over 12 days while matching the symptoms described in ancient accounts.
Who Stood to Gain?
Alexander’s sudden death came at the peak of his power, just as he was planning further conquests. His demise left a vacuum that plunged his empire into chaos and ignited the Wars of the Diadochi—a brutal power struggle among his generals and successors. With no clear heir and a fragile coalition of advisors, many in his court had both motive and opportunity to eliminate him.
Though some ancient sources accused figures like Antipater, his son Iollas (who poured Alexander’s final drink), and even Aristotle of involvement, historians such as Plutarch dismissed the poisoning theory outright. But with modern toxicology backing the timeline and symptoms, the theory now has a stronger scientific foundation than ever before.
Still a Mystery
Despite the compelling evidence, Alexander’s tomb and remains have never been found—leaving toxicological testing impossible. Natural causes such as typhoid fever, malaria, or autoimmune conditions like Guillain–Barré syndrome remain possible explanations.
Yet the white hellebore theory introduces a credible, historically grounded scenario that blends political intrigue, botanical knowledge, and slow-acting science. If true, it reveals that one of history’s most celebrated figures may have fallen not in battle, but to a carefully timed dose of poison—administered in the very heart of his inner circle.
