That'true. monarch 1 butterflies lay their eggs on milkweed plants.The caterpillars 2 feed on milkweed, from which they extract substances called cardenolides, a type of chemical that can cause heart arrhythmia. This toxin 3 doesn’t affect the caterpillars themselves, but it makes them poisonous or distasteful to most predators 4.But it’s not just monarchs 5 that like milkweed, scientists are discovering new uses for many parts of this perennial 6 plant that grows along roadsides and fields. The large seed pods contain thousands of seeds, each with a feather white tuft of silky fibers 8. These fibers help the seeds disperse 9 in the wind.It turns out that these milkweed fibers are excellent insulation 10, superior even to down feathers. One company has started marketing 11 milkweed fiber 7 as hypoallergenic filler for comforters and pillows.Chemists at the National Center for Agricultural Utilization 12 Research have also discovered that the seed pulp 13 left after the fibers are removed can be used to kill destructive soil nematodes and other agricultural pests.Yet another study found that milkweed oil is high in vitamin E, and is free from the toxins 14 found in other parts of the plant. The oil from milkweed can make an ideal ingredient for moisturizers, cosmetics 15 or even biodiesel fuel.
