The tree is showy when in flower and is often cultivated in the tropics. In 

 Florida it is known as " trumpet-flower " and " yellow oleander," and in the 

 British West Indies as " lucky-nut," and " luck-seed." The flowers are very 

 sweet-scented. The wood is said to be soft and fibrous and to have a specific 

 gravity of about 0.80. The milky juice and the seeds are poisonous. In Yuca- 

 tiin cotton soaked in the juice is placed in cavities in teeth to relieve tooth- 

 ache. The seeds have been reported to yield a glucoside, thevetine. A tinc- 

 ture of the bark is considered a powerful febrifuge and in large doses is a 

 violent purgative and emetic.

The seeds contain about 40 per cent of oil and also a glucoside, thevetin, 

 and they are considered very poisonous. Taken internally they act as a 

 violent vomitive, hinder respiration, and cause paralysis of the heart. 

 They have been given in Mexico as a substitute for digitalis, but their use is 

 dangerous. They are a popular remedy for hemorrhoids, and some of the 

 Indians consider them a remedy for rattlesnake bites. They are said to have 

 been worn about the ankles as rattles in certain dances. The leaves or the 

 juice were emplojed by the Aztecs for deafness, cutaneous diseases, ulcers, 

 and toothache.
