Said to be known in the British West Indies as " bread-and-cheese." The 

 plant is used in Tabasco and elsewhere for stupefying fish, and the stems are 

 utilized as a substitute for rope. The bark has a musklike odor, and is said 

 to contain an alkaloid, timbonine. The leaves have been applied as poultices 

 for liver affections and the oil from the seeds as an anodyne liniment, while 

 the plant has been used also as a remedy for gonorrhoea. Some of the Indians 

 are said to have used the juice to poison their arrows, and it is reported that 

 in the Antilles the negroes have made use of the seeds for criminal poisoning.
