How much oleander is toxic to humans?

What happens when you eat yellow oleander?
Oleander (Nerium oleander) is a flowering shrub. It contains chemicals called toxic cardiac glycosides, which can lead to death when consumed. The cardiac glycosides in oleander affect the heart. These chemicals can slow the heart rate down.
Why is oleander toxic?
Oleander is also used as an animal poison, which is best illustrated by its role as a rat poison. All parts of the nerium oleander are poisonous, primarily due to the contained cardiac glycosides—that is, oleandrin, nerin, digitoxigenin, and olinerin of which oleandrin is the principal toxin.
How is oleander poisoning detected?
Oleandrin, the toxic glycoside in oleander, can be detected in blood by high-performance liquid chromatography and mass spectrometry (HPLC/MS).
Has anyone died from eating oleander?
