Pulvis Kino Compositus. Lond. Dub. Compound Powder of Kino

"Take of kino, fifteen drachms; cinnamon, half an ounce; hard opium, a drachm. Rub them separately to a fine powder, then mix."

This is a bad form of an astringent anodyne powder. The dose is from grs. x. to Эj. Twenty grains of the powder contain one grain of opium.

Pulvis Quercus Marinae. Dub. Powder of Yellow Bladder Wrack

"Take of bladder-wrack in flower, any quantity. Let it be dried and freed from the sordes, then exposed to heat in an iron vessel or crucible, to which a perforated lid is adapted, until, the vapours ceasing, it becomes obscurely red hot. Reduce the carbonaceous matter which remains to powder."

This powder is a mixture of soda, iodine, and charcoal. (For its medicinal effects, see Fucus, Part ii.)

Pulvis Salinus Compositus. Edin. Dub. Compound Saline Powder

"Take of pure muriate of soda, sulphate of magnesia, of each four parts; sulphate of potassa, three parts. Dry the salts with a gentle heat, then pulverize them separately, and afterwards rub them together. Preserve the powder in a well-stopped phial.

This powder is a simple purgative, and does not appear to possess any peculiar advantages.

Pulvis Scammonii Compositus. Lond. Dub. Compound Powder of Scammony

"Take of scammony, hard extract of jalap, each two ounces; ginger root, half an ounce. Rub them separately to a very fine powder; then mix."

Pulvis Scammonii Compositus, Edin. Compound Powder of Scammony.

"Take of scammony, supertartrate of potassa, of each equal parts. Rub them together to a very fine powder."

Syn. Poudre de Scammonee composee (F.).

These powders, although agreeing in name, differ very considerably in their nature. In the first, the activity and the stimulating quality of the scammony are increased by the jalap, while the griping effect of the mixture is in some degree obviated by the ginger. In the second, the addition of the bitartrate of potassa detracts from the violence of the operation of the scammony, and renders it less irritating; although, at the same time, more certain. The dose of the first is from grs. x. to grs. xx.; that of the second, from grs. x. to 3ss. They are chiefly used in hydropic and worm cases.

Pulvis Scillae

Dub. Powder of Squill "Let squill roots (bulbs), freed from their membranous integuments and cut in transverse slices, be dried upon a sieve with a low degree of heat; and then reduce them to powder, which must be preserved in well-stopped glass phials.".

Pulvis Spongiae Ustae. Dub. Powder of burnt Sponge

"Let sponge cut into small pieces, be beaten so as to free it from little stones; then burn it in a covered iron vessel, until it becomes black and friable; finally, reduce it to powder."

Pulvis Aluminis Compos1tus. Edin. Compound Powder of Alum

"Take of sulphate of alum, four parts; kino, one part. Rub them together to a fine powder."

This is a powerful astringent powder, and is sometimes used internally in menorrhagia and diarrhoea; but is more generally employed as an external application. The dose is from grs. x. to grs. xv.; but it must be taken in the dry state, as the kino is decomposed by the alum, when a fluid vehicle is employed."

Pulvis Tragacanthae Compositus. Lond. Compound Powder of Tragacanth

"Take of tragacanth, powdered, acacia, powdered, starch, of each an ounce and a half; sugar, three ounces. Powder the starch and the sugar together; then add the tragacanth and the acacia, and mix the whole together."

Syn. Poudre composee de Tragacanthe (F.), Tragacanthe Gummi pulver (G.) Polvere di Tragacanta composta (I.).

The starch might well be omitted in this powder, as it is insoluble in cold water. The powder is efficaciously used as a demulcent in hectic fever, and to allay the tickling cough of catarrh: in gonorrhoea and strangury it is given combined with nitre, and in dysentery with ipecacuanha powder. The dose is from 3 ss. to 3 iij. mixed in water, or any bland fluid.

Pulvis Pro Cataplasmate. Dub. Powder for Cataplasms

"Take of linseed oil cake, one part; oatmeal, two parts. Mix."

An excellent material for making poultices.
