Description
The milkweed filaments from the follicles are hollow and coated with wax, and have good insulation qualities. During World War II, over 5,000 t (5,500 short tons) of milkweed floss was collected in the United States as a substitute for kapok.[citation needed] As of 2007, milkweed is grown commercially as a hypoallergenic filling for pillows. A study of the insulative properties of various materials found that milkweed was outperformed by other materials in insulation, loft, and lumpiness, but scored well on various metrics when mixed with down feathers.

Seeds.
In the past, the high dextrose content of the nectar led to milkweed's use as a source of sweetener for Native Americans and voyageurs.
The bast fibers of some species can be used for cordage.
Milkweed latex contains about 1 to 2% latex, and was attempted as a source of natural rubber by both Germany and the United States during World War II. No record has been found of large-scale success.
Milkweed is beneficial to nearby plants, repelling some pests, especially wireworms.
Milkweed also contains cardiac glycoside poisons which inhibit animal cells from maintaining a proper K+, Ca+ concentration gradient. As a result many natives of South America and Africa used arrows poisoned with these glycosides to fight and hunt more effectively. Milkweed is toxic and may cause death when animals consume 10% of their body weight in any part of the plant.[citation needed] Milkweed also causes mild dermatitis in some who come in contact with it.
Being the sole food source of monarch butterfly larvae, the plant is often used in butterfly gardening.
In a garden, milkweed flowers will produce a strong and beautiful fragrance that will be as powerful as in any other flower.
