Saricin.—A crystalline glucoside obtained from the bark 
of salix alba ; also from the bark of various species of populus

periodic, and has been recommended in intermittents as a 
substitute for cinchona. Dose: 3 to 20 grains, Safe in these 
doses. 6d. per drachm. 
SANTONIN.—A crystalline neutral principle obtained from 
worm seed. Administered internally, santonin sometimes 
causes yellow or green vision, and again, even in a three 
grain dose, it stains the urine of a yellow colour. This effect 
may continue for two or three days, and is sometimes attended 
by irritation of the bladder. It is employed as an anthel- 
mintic. Its small bulk and comparative tastelessness render 
it very suitable for children. It should be followed by a 
mild purgative. Dose, one to three grains for a child; two 
to six grains for an adult. Dangerous in overdoses. 6d per 
drachm. 
SCAMMONY, Resin of.—A resin obtained from dry 
scammony root by means of rectified spirits. A drastic 
purgative, generally causing much watery discharge, and 
often griping. Useful to give activity to other purgatives, 
which appear to diminish its violence. It is employed in 
cerebral and dropsical effusions, torpidity of bowels, and as a 
vermifuge for children. Dose, three to eight grains. Care in 
use.
