Editing Cardiac glycoside (section)

=== Classification ===
[[File:Oleandrin.svg|thumb|class=skin-invert-image|Example of the chemical structure of [[oleandrin]], a potent toxic cardiac glycoside extracted from the [[Oleander]] bush.]]
Cardiac glycosides can be more specifically categorized based on the plant they are derived from, as in the following list. For example, cardenolides have been primarily derived from the foxglove plants ''[[Digitalis purpurea]]'' and ''[[Digitalis lanata]]'', while bufadienolides have been derived from the venom of the [[cane toad]] ''Rhinella marina'' (formerly known as ''Bufo marinus''), from which they receive the "bufo" portion of their name.<ref name=EmedPoison>{{Cite journal|date=2017-05-05|title=Cardiac Glycoside Plant Poisoning: Practice Essentials, Pathophysiology, Etiology|url=http://emedicine.medscape.com/article/816781-overview |website=Medscape |publisher=WebMD}}</ref> Below is a list of organisms from which cardiac glycosides can be derived.
