Many of the plants of this order possess a saponaceous principle. 

 Some of these are poisonous in whole or in part. The Genip has 

 eatable fruit and that of the Akee is eatable in part, and is used 

 as a remedy in dysentery ; the Akee is considered poisonous when 

 raw, wholesome cooked. Serjania is very poisonous.

These plants have an acrid, sometimes very poisonous juice, but 

 some of the fruits are largely eaten, e. g. Mango and Cashew-nut. 

 The eatable portion in this last case is the swollen peduncle upon 

 which the nut is borne. The acrid oil in the nut is very poisonous, 

 and is said in the Bahamas to kill Chigoes and cure freckles, and to 

 be useful applied to ulcers. A decoction of the leaves is said also 

 to be a useful wash for ulcers. The Cashew-nut and the Hog-plum 

 are said to be good for dropsy. The fruit of the latter is used for 

 feeding swine. The species of Rhus are poisonous. 



The Mangoes of the Bahamas are of comparatively poor quality, 

 the best are known as " Number Thirteen " — a variety which 

 attains great perfection in Jamaica. 



The island of Itamaraca, off the coast of Pernambuco, is said to 

 produce the finest Mangoes in the Western Hemisphere.
