 Dolichos pruriens, Lin. spec. 1020. Lam. diet. 2. p. 290. Stizo- 

 lobiuni pruriens, Pers. Carpopogon pruriens, Roxb. Flowers vio- 

 laceous, becoming black when dried. Perhaps the American, Asia- 

 tic, and African plants are the same. A decoction of the roots is 

 said to be a powerful diuretic. The pods are about 4 inches long, 

 thickly beset on the outside with stiff brown hairs, which, when 

 applied to the skin, occasion a most intolerable itching. In the 

 choice of Con-itch, all those pods which are brown or shrivelled, 

 rusty, or of a bad colour or diminutive size, ought to be re- 

 jected. In medicine, the ripe pods are dipped in syrup, which 

 is again scraped off with a knife. When the syrup is rendered 

 as thick as honey by the hairs, it is fit for use. It acts mecha- 

 nically as an anthelmintic, occasions no uneasiness, and may be 

 safely taken from a tea-spoonfidl to a table-spoonfull in the 

 morning, fasting. The worms are said to appear with the second 

 or third dose. A vinous infusion of the pods (12 to a quart) 

 is said to be a certain remedy for the dropsy. A strong infusion 

 of the roots sweetened with honey is used in India by the 

 native practitioners in cases of cholera morbus.
