b. Essential oil from the herb. 



Note. Official in the Indian Pharmacopoeia, p. 40. Formerly much 

 used in this country as a stimulant and deobstruent. It was also sup- 

 posed to ward off pestilence. See Treat. Bot., p. 1001. For fig. of the

101. XANTHOXYLON CLAVA-HERCDLIS, L. 



a. Stem. 

 6. Bark. 



c. Enlarged prickles from stem. 



Note. The bark is used in the West Indies for malignant ulcers, and 

 is used both externally and internally as an alterative in syphilis. It is 

 official in the secondary list of the United States Pharmacopeia, under 

 the name of X. Caroliniannm. The prickles are worthy of notice on 

 account of their extraordinary development. The specimen b accord- 

 ing to Prof. Bentley, is probably that of X. Carolinianum, Lam., which is 

 apparently a variety of X. fraxinenm growing in the Southern States. 

 See P. J. [1] , vol. xvi., p. 271. 



102. XANTHOXYLON FEAXINEOM, Willd. (Prickly Ash, Toothache Shrub.) 



a. Stem. 



b. Bark. 



c. Fruit. 



Note. The bark is used in the United States as a permanent arterial 

 stimulant, and as an alterative in syphilis and rheumatism. It resembles 

 Gnaiacum in its stimulant action, but is more permanent. The bark 

 resembles that of Pomegranate root bark, but nitric acid colours it red, 

 while it does not affect Pomegranate root bark. See P. J. [2] , vol. iv., 

 p. 399.
