History

The scientific name Asclepias comes from the Greek god of medicine Asklepios. Tuberosa refers to the tuberous roots. The name pleurisy root comes from its medicinal use to treat lung inflammations (pleurisy).

Where is it found?

Butterfly weed is native to North America, and is found in the Eastern, Central and Souther United States and Ontario and Quebec in Canada.

It can be found in dry/rocky open woods, glades, prairies, fields and roadsides.

The plant is drought tolerant and likes dry to medium and well-drained soils in full sun. It also does well in poor dry soils. It self-seeds but can take 2-3 years to flower as it;s slow to establish itself. The deep roots make it hard to transplant. Crown can rot in wet and poorly drained soils.

What's it used for?

The plant stems, leaves, flowers and seed pods have been eaten and used for clothing. Seed pods can be cooked young. The flowers taste like sweet peas when cooked. Leave and new buds taste like spinach when cooked. Stems can be made into a quality fiber for weaving into twine and cloth.

The root is harvested in the fall and used as an antispasmodic, carminative, mildly cathartic. It is a diaphoretic, diuretic, expectorant, tonic as well as a vasodilator. It's used to treat coughs, pleurisy (swelling of the lining of the lungs), pneumonitis (swelling of the air sacs in the lungs), bronchitis (swelling of the airways), influenza, and swine flu.

Other uses include disorders of the uterus, muscle spasms, and pain, loosening mucus so it can be coughed up, to promote sweating, diarrhea, dysentery, chronic rheumatism, and as an expectorant.

Are there any risks?

Toxic in large quantities. Safety concerns comes from the powerful chemical similar to digoxin (Lanoxin) which might cause heart problems. The root can also cause nausea, vomiting and skin rashes. Women who are pregnant or breast feeding should avoid it as it can stimulate the uterus and act like the hormone estrogen.

Avoid using is you have a heart condition as it might interfere with medicine used to treat heart problems.

Don't take pleurisy root with Digoxin (Lanoxin) which can increase heart rate more and increase the side effects of the drug, estrogen pills, or water pills (diuretic drugs) like chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide) that can cause low potassium levels and affect the heart.
