TlNCTURUS.

TART III.

The smallness of the fibres of the root of black hellebore,which are the parts medicinally employed, renders it almostimpossible to follow the direction of the London formula; andit is better to powder it coarsely, as ordered by the DublinCollege. This tincture was regarded by Dr. Mead as a power-ful emmenagogue, and is still ordered in uterine obstructions,and in some cutaneous affections. The dose is from v[ xxx. tof sj. in any appropriate vehicle.

TINCTU'RA HU'MILI. Lond. Edin. Tincture of Hops. ■

" Take of hops, fve ounces ; proof spirit, txvo pints, (twopounds and a half, Edin.) Macerate for fourteen days, andstrain; (seven days express the tincture, and filter throughpaper. Edin.)"

The lightness and bulk of the hops render it difficult tomake the quantity of spirit here ordered act equally on the in-gredients, therefore their surface should be several timeschanged by stirring, during the maceration, and the tinctureexpressed as ordered by the Edinburgh College. The tinc-ture is supposed to possess the tonic and narcotic propertiesof the plant, and has been recommended as a substitute fortincture of opium in gout and rheumatism', but from theexperiments of Dr. Bigsby, its efficacy is very 7 probematica!.The dose is from f^fs. tof ^ij. or more.

TINCTU'RA HYOSCY'AMI. Lond. Tincture of Hen-bane.

" Take of the dried leaves of henbane, four ounces; proofspirit, ttxopints. Macerate for fourteen days, and filter."

Dublin.

" Take of the dried leaves of black henbane in coarse pow-der, two ounces and a quarter; proof spirit, a pint. Digest forseven days ; then strain."

Tinctura Hyoscyami nigri. Edin. Tincture of BlackHenbane.

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

I have found this a more useful substitute than tincture ofhops, for tincture of opium. In a dose of fy. it seldomfails of procuring sleep and quiet; and does not affect thehead, or produce costiveness. In cases of diarrhoea, when thistincture is given, it will be necessary to add a few dropsof tincture of opium to counteract the tendency it has to runoff by the bowels.
