allowing. This woman had suffered the complaint three
years, and was greatly reduced, being totally unable to swallow solids,
and liquids but very imperfectly.--Woodville's Med. Bot. p. 720.

199. DATURA Stramonium. THORN APPLE. The whole Plant. E.--Dr. Woodville
informs us, that an extract of this plant has been the preparation
usually employed, and from one to ten grains and upwards a-day: but the
powdered leaves after the manner of those directed for hemlock would
seem, for the reason given, to be a preparation more certain and
convenient.

It has been much celebrated as a medicine in epilepsy and convulsions
and mania; but it is of a violent narcotic quality, and extremely
dangerous in its effects.

Stramonium has been recommended, as being of considerable use in cases
of asthma, on the authority of some eminent physicians of the East
Indies; and the late Dr. Roxburgh has stated to me many instances
wherein it had performed wonders in that dreadful malady.

The Datura Metal, Purple-flowered Thorn-apple, is much like the
Stramonium, except in the flowers and the stalks being of a purple
colour. I have made particular inquiry of Dr. Roxburgh if any particular
kind was used in preference, and he said not; that both the above sorts
were used; and, in fact, not only these, but the Datura Tatula, another
species which grows wild there, and is cultivated in our stoves for the
sake of its beautiful flowers, is also used for the same purposes.

The mode of using it was by cutting the whole plant up after drying, and
smoking it in a common tobacco-pipe; and which, in some cases in this
country also, has given great ease in severe attacks; and I know several
persons who use it with good effect to this day. In vegetables of such
powerful effects as this is known to have, great care ought to be taken
in their preparation, which, I fear, is not always so much attended to
as the nature of this subject requires [Footnote: See Observations on and
Directions for preparing and preserving Herbs in general, et the end of

200. DAUCUS sylvestris. WILD CARROT. The Seeds. L.--These seeds possess,
though not in a very considerable degree, the aromatic qualities common
to those of the umbelliferous plants, and hence have long been deemed
carminative and emmenagogue; but they are chiefly esteemed for their
diuretic powers, and for their utility in calculus and nephritic
complaints, in which an infusion of three s
