42 FLORA HOMCOPATHICA. 
plant is mixed with equal parts of alcohol. For external use, 
as an application for contusions, etc., it is prepared as follows: 
the parts of the root selected should be about the size of a quill, 
the smaller fibrils being removed; this should be reduced to 
coarse powder and macerated in alcohol, and allowed to stand 
in a cool place eight or ten days, and then strained and de- 
canted; great caution is necessary in the local application of 
this tincture, particularly in cases where there is abrasion of the 
skin, in such the tincture should be greatly diluted with water; 
in fact, in many cases it can hardly be applied weak enough. 
Before making use of this plant, it is indispensable to clean 
the flowers, as they are often soiled by the eggs of the parasitical 
fly, previously mentioned, and it must be borne in mind that the 
root soon loses much of its medicinal virtue if exposed to the air, 
but if reduced to powder and dried in a sand-bath, and then 
placed into well-stopped bottles, it may be preserved for years. 
From the very great demand for this drug for contusions, etc., 
a spurious root has been sent over from the Continent, and the 
author has seen bottles labelled « Tincture of Arnica Montana,” 
which he has every reason to suppose did not contain one drop 
of the juice of that plant. It is therefore of the last importance 
that those interested either in the sale or the use of it, should be 
aware of its distinguishing characteristics.
