Action and Therapy.—This is an old American medicine that was formerly employed as a substitute for ipecac. It is less active than Euphorbia corollata, but like it produces emeto-catharsis. In small doses it quiets irritation of the mucous membranes, proving useful in both gastrointestinal and bronchial disorders. The indications and uses are practically the same as those given for Euphorbia corollata, which see. Besides, it has been advised in irritative dyspepsia, and jaundice with obstinate hepatic torpor. For the latter purposes the larger doses are to be employed.
