176 THE MEDICINAL PLANTS OF THE PHILIPPINES 



Ipomoea Turpethum, R. Br. (Convolvulus Turpethum, L.; 

 C. maximus, Blanco.) 



NOM. VULG. Albohol, Sp.; Turpelh Root, Indian Jalap, Eng. 



USES. The root, known in the Philippines as " turbita," is 

 a purgative and is a component part of the tincture of jalap,
