Pleurisy dried roots have traditionally been used specifically for pleurisy, but also for bronchitis and gastroenteritis. The plant is still commonly used to help support these ailments in the United Kingdom but is less popular in mainland Europe and other parts of the world.
Description: The plant is a sparse, single-stemmed perennial herb of up to 0.6 m high with narrowly oblong leaves and attractive orange flowers that are arranged in clusters at the branch tips. The seeds are borne in pointed capsules and are dispersed by means of silky seed haits.
Active Ingredients: The chemical compounds of A. tuberosa are poorly recorded but it shares with other Asclepias species the presence of cardiac glycosides of the cardenolide type, such as glucofrugoside, frugoside and coroglaucigenin, and others. Flavonols, flavonol glycosides, phytosterols and triterpenes are also present.
Health Effects: Pleurisy root stimulates the heart and circulation. The cardiac glycosides are known to cause nausea and vomiting in larger doses. Animal studies showed uterotonic and oestrogenic effects but efficacy for the traditional indications has yet to be proven scientifically. Since cardenolides can also act as saponins, a positive secretolytic effect appears plausible.
Notes: Three other species, milkweed (Asclepias syriaca), swamp milkweed (A. incarnata), and Curassavican swallow-wort (A. curassavica) have been used as expectorants and to help support asthma. In Africa, A. crispa, A. fruticosa and A. physocarpa are popular in traditional medicine to help support various ailments, ranging from stomach complaints to tuberculosis and headache.
Status: Traditional health; Pharm.
Preparation and Dosage: A dose of 1 - 4 g ofdried root is taken three times per day by infusion. Tinctures of 1:10 in 45% alcohol are taken in 1 - 5 mL quantities three times per day.
