Tinctura Hellebori. Lond. Tincture of Hellebore

" Take of the root of (black) hellebore, sliced, five ounces; proof spirit, two pints. Macerate for fourteen days, and filter."

Edinburgh. Dublin.

"Take of black hellebore root, bruised (powdered, Dub.), two ounces; cochineal in powder, fifteen grains (two scruples, Dub.); proof spirit, fifteen ounces (two pints, Dub.). Digest for seven days, then filter through paper."

Syn. Teinture d'Ellebore noir (F.), Tintura d'Elleboro (I.)•

The smallness of the fibres of the root of black hellebore, which are the parts medicinally employed, renders it almost impossible to follow the direction of the London formula; and it is better to powder it coarsely, as ordered by the Dublin College. This tincture was regarded by Dr. Mead as a powerful emmenagogue, and is still ordered in uterine obstructions, and in some cutaneous affections. The dose is from xxx. to f 3 j. in any appropriate vehicle.

Tinctura Hyoscyami. Lond. Tincture of Henbane

" Take of the dried leaves of henbane, five ounces; proof spirit, two pints. Macerate for fourteen days, and filter."

Dublin.

" Take of the dried leaves of black henbane in coarse powder, five ounces; proof spirit, two pints. Digest for seven days; then strain."

1 Tinctura Hyoscyami nigri, Edin. Tincture of Black Henbane.

1 Tinctura melampodii, P, L. 1745. Tinct. Hellebori nigri, P. L. 1824.

"Take of the dried leaves of black henbane, an ounce; proof spirit, eight ounces. Digest for seven days, and filter through paper."

This is a much more useful substitute for tincture of opium than the tincture of hops. In a dose of f 3 j. to 3 ij. it seldom fails of procuring sleep and quiet; and does not affect the head or produce costiveness.

Tinctura Jalapae. Lond.1 Tincture of Jalap

"Take of jalap, powdered, ten ounces; proof spirit, two pints. Digest for fourteen days, then filter."

Dublin.

"Take of jalap root in coarse powder, eight ounces; proof spirit, two pints. Digest for fourteen days, then filter."

Tinctura Convolvuli Jalapae, Edin. Tincture of Jalap.

"Take of jalap root in powder, three ounces; proof spirit, fifteen ounces. Digest for seven days, and filter through paper."

Proof spirit extracts the active principles of jalap, namely, the gum, extractive, and resin, all of which are requisite for the production of its full cathartic effect. The great difference in point of strength of these tinctures is much to be regretted. Dose f 3 j. to f 3 iij.

Tinctura Iodini1 Composita. Lond. Compound Tincture of Iodine

"Take of iodine, an ounce; iodide of potassium, two ounces; rectified spirit, two pints. Macerate until they are dissolved, and filter."

Tinctura Iodinii, Dub. Tincture of Iodine.

"Take of iodine, two scruples; rectified spirit, one ounce. Mix and dissolve the iodine by the aid of heat. Keep the mixture in a closely-stopped phial."

This is a saturated spirituous solution of iodine, with the addition of the iodide of potassium in the London preparation, which adds nothing to its power. It is a convenient mode of administering iodine. The dose is from ten minims, gradually increased to sixty twice or three times a day.
