ARNICA MONTANA. 
309 
The root is about the thickness of a quill, and two to three 
inches long. When dry it is shrunken, dark brown in 
colour, brittle, and has a bitter taste, which continues for 
some time on the palate. It contains a small quantity of a 
volatile oil; 1’5 of a greenish-yellow resin, soluble in spirit; 
15*0 of yellowish brown extractive matter; 17*5 of a greenish 
brown resin, with acetates and malates, and 600 of vegetable 
fibre. Its efficacy depends on the stimulating extractive 
matter and the resin. 
Given internally, arnica acts powerfully on the nervous and 
vascular systems, promoting absorption. It may, therefore, be 
employed in aesthenic fever, nervous and gastric fever, when 
the inflammation is removed ; also in typhous inflammation, 
(viz., on the lungs.) Likewise in cases of effusion into the 
cranium and spinal canal ; in the second stage of subacute 
inflammation of the brain, and lastly, in obstinate rheu- 
matism. 
The flowers are given in powder, or as an electuary or 
pill, or, what is better, in infusion ; to make which, take

and let them stand together until cold. 
This dose may be given two to three times in the day to 
large animals. 
The administration of Arnica may be also in conjunction 
with Antim. tart., Ammon., Hydrochlor., and the mineral 
acids ; or combined with volatile stimulants, such as Carn- 
phor, 01. Terebinth., Liq. Amm., Ammon. Carb., &c.
