BOTANIC MATERIA MEDICA. 223 
The hop is one-seeded, which seed is covered by 
a granular substance, the lupuline of the stores. 
The hop as found in the stores is somewhat 
ovate in form, and made up of a number of 
scales, which have a greenish-gray appearance. 
These scales are finely netted in pattern at the 
upper half, whilst the lower portion are par- 
allel-veined, The hop as found in the stores 
corresponds to the description given, except so 
far asthe color. This it loses in the process of 
drying. 
Hops and their preparations are Sedative, an- 
odyne and tonic in their effects, and are given 
in form of extract, fluid extract, tincture and 
infusion, all of which are officinal. The dose is 
from 5 to 15 grains of the extract; of the tinc- 
ture, 1 to 2 fluid drachms; of the infusion, 1 to 
2 tablespoonfuls. 
The hop plant has been known from the 
earliest history of medicine, and introduced into

earth, alluding to the situation in which the 
vine grows best. : oe
