CASSIA SENNA. 
indicated, we should prefer the Henbane or Digitalis, as remedies 
which have not been found to produce those alarming symptoms 
that have so frequently followed the use of Stramonium. 
We have next to consider the mode of administering it, and here 
we may remark, that, reasoning by analogy, we should conclude the 
system might be so habituated to the use of Stramonium, like the 
other narcotics, as to bear a dose, which under other circumstances, 
must prove fatal. The inspissated juice of the leaves has been most 
commonly used, and of this a quarter of a grain is considered a 
sufficient dose at first. Dr. Barton gives it in powder, beginning 
with doses of three or four grains, and increasing them in a few days 
to fifteen or twenty. In a case where it was exhibited to the extent 
of thirty grains, it dilated the pupil of one eye, and produced 
paralysis in the eyelids, which was removed by a blister. A tincture 
made from the seeds has also been used. As an external application, 
an ointment prepared from the leaves, has been found to give ease 
in haemorrhoids and in inflammation ; and, accoiding to Plenck, the 
fresh leaves bruised, soften hard and inflamed tumours, and discuss 
tumours from indurated milk in the breasts of nurses.
