Therapy. Asclepias is one of the most important medicines for broncho-pulmonic inflammations and catarrhs, and an agent for re-establishing suppressed secretion of the skin. It is the most perfect diaphoretic we possess, so completely does it counterfeit the normal process of insensible perspiration.
Therapy. It is beneficial in acute pleuritis specifically, also in bronchitis, pneumonitis and peritonitis. It has distinct expectorant properties. In tight and painful coughs with difficult respiration, especially where there is a general suspension of secretion, with dry skin and mucous membranes, and in soreness of the chest from coughing, it is a most excellent remedy.
Properties and Uses. The root of this plant is probably one of the most reliable and serviceable relaxing diaphoretics in the whole Materia Medica. It diffuses itself with only moderate rapidity, but maintains its influence with considerable pertinacity.
Action, Medical Uses, and Dosage. Very useful diaphoretic in coughs, colds, and as a drink in febrile diseases. Two drachms of the powder may be infused in ½ pint of boiling water, sweetened, and drank in wineglassful doses, every 1 or 2 hours. Or in common colds, the ½ pint of warm infusion may be taken at a draught, and repeated in an hour if necessary (Wm. S. Merrell).
