Veratria and its salts, though ina much less degree. It excites a 
little heat in the stomach, but does not act upon the bowels, and after 
several doses have been taken it occasions sensations of tingling in 
the extremities, but very slightly. Internally it has effects on dis- 
ease similar to those of Veratria, but it is much inferior as a medicinal 
agent. | 3 \ 
When used in the form of embrocation or ointment, Sabadilline 
has more powerful effects. It excites a peculiar feeling of heat and 
pulsation in the part where it is rubbed, and this is accompanied by 
a sensation, as if the part had been severely bruised, which continues 
often for some hours. | | | 7 
The ointment employed may contain from fifteen to twenty grains 
to an ounce of lard, and may be rubbed for fifteen or twenty minutes, 
or until the heat and pulsation show themselves; sometimes a slight 
eruption comes out on the skin where it is rubbed, but it is not at-. 
tended with an inconvenience. I have used the ointment of Saba- 
dilla in friction, in neuralgic affections, and in rheumatism, gout, &c. 
~ Its effects are similar to those of Veratria, but not so beneficial. It 
cannot, however, be said that the remedy has had a fair trail, as very 
little of it has as yet been made, and what I have used has not been 
in a state of purity. : ines ve 
Mono-HypraTE OF SABADILLINE differs nothing in general cha- 
racter from Sabadilline, except that it has a yellowish colour, and is 
incrystallizable ; it has nearly the same chemical constitution, and 
indeed M. Couerbe considers the two substances as differing in 
nothing, except that Sabadilline has two atoms of water of erystalli- 
zation, whilst the mono-hydrate has only one. From their similari- 
ty in these respects it may be inferred that they have similar 
oe properties, although the mono-hydrate has not hitherto been 
used. aie) | . 
The only thing connected with this part of the subject which 
remains to be noticed, is the use of the salts of Veratria externally. 
Several of these have been employed, and appear to be possessed of 
effects very similar to those of the base itself. Hither the sulphate, 
acetate, or tartrate, may be used, in the proportion of from ten to 
fifteen grains to an ounce of lard ; they make an ointment that oc- 
casions a powerful sensation of heat and tingling, when rubbed upon 
the skin, and may be resorted to, and perhaps with advantage, when 
Veratria, as sometimes happens, has become less efficacious from 
continued use. , |
