"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.


Glycosides are ethers that consist of a carbohydrate moiety joined by an ester bond to a noncarbohydrate moiety (referred to as the aglycone). The structure and/or properties of their aglycone is used to group and identify them. For example, isoflavones are glycosides with a flavone aglycone, and cardiac glycosides are steroid glycosides that act as powerful stimulators of the heart.
