the fresh
flowers are gently laxative and aperient; when dry, they are said to
promote chiefly the cuticular excretion, and to be particularly
serviceable in erysipetalous and eruptive disorders.--Woodville's Med.
Bot. 598.

269. SCILLA maritima. SQUILL. Root. L. E. D.--This root is to the taste
very nauseous, intensely bitter and acrimonious; much handled, it
exulcerates the skin. With regard to its medical virtues, it powerfully
stimulates the solids, and attenuates viscid juices; and by these
qualities promotes expectoration, urine, and perspiration: if the dose
is considerable, it proves emetic, and sometimes purgative. The
principal use of this medicine is where the primae viae abound with mucous
matter, and the lungs are oppressed by tenacious phlegm.

270. SCROPHULARIA nodosa. KNOTTY FIGWORT. Herb. D.--The roots are of a
white colour, full of little knobs or protuberances on the surface: this
appearance gained it formerly some repute against scrophulous disorders
and the piles; and from hence it received its name: but modern
practitioners expect no such virtues from it. It has a faint unpleasant
smell, and a somewhat bitter disagreeable taste.

271. SINAPIS nigra. BLACK MUSTARD. Seeds. L. E. D.--By writers on the
Materia Medica, mustard is considered to promote appetite, assist
digestion, attenuate viscid juices, and, by stimulating the fibres, to
prove a general remedy in paralytic and rheumatic affections. Joined to
its stimulant qualities, it frequently, if taken in considerable
quantity, opens the body, and increases the urinary discharge; and hence
has been found useful in dropsical complaints.--Woodville's Med. Bot. p.
404.

272. SINAPIS alba. WHITE MUSTARD. Seeds. L. E. D.--These have been
recommended to be taken whole in cases of rheumatism and have been known
to produce considerable relief.

273. SISYMBRIUM Nasturtium. WATER-CRESSES. Herb. E.-Hoffman recommends
this as of singular efficacy for accelerating the circulation,
strengthening the viscera, opening obstructions of the glands, promoting
the fluid secretions, and purifying the blood and humours: for these
purposes, the expressed juice, which contains the peculiar taste and
pungency of the herb, may be taken in doses of an ounce or two, and
continued for a considerable time.

274. SIUM nodiflorum. CREEPING WATER-PARSNEP. The Root. D.-This plant
has not been admitted into the Materia Medica of any of the
Pharmacopoeia
