How toxic is milkweed to humans?
Although many milkweeds contain resinoids, most of the ones that cause fatal poisonings contain cardenolides (cardiac glycosides). These cardenolides are similar to digoxin causing electrolyte balances in heart muscle resulting in arrhythmias and cardiac failure. The toxic nature of milkweed is due to one of two agents: cardiac glycosides (cardenolides) or an unidentified neurotoxin. The cardiac glycosides are found in the majority of milkweed species, while the neurotoxin is specific to the whorled-leaf types such as horsetail milkweed.Medicinally, the plant (especially the root) was used widely as a kidney and urinary aid, cathartic, diuretic, and emetic. All species of Asclepias are distasteful to livestock and pets.
