The Ipomcea cathartica is Pharbitis c. The Flore medicale des Antilles states that 

 M.Bauduit,a rich proprietor of S. Domingo discovered m this plant a resinous 

 juice, which coagulates and proves to be profusely purgative. He formed of it a 

 much-approved syrup, which in the French colonies bears his name. This sji up 

 is very active, and requires, on account of its drastic properties, to be used with 

 great caution. — Hooker.
