two pints and a half. Digest for seven days, and filter throughpaper.
This is an elegant stomachic bitter and cordial; but in dys-pepsia, in which it is more particularly indicated, the infusionis preferable.
TINCTURA GUAI'ACI. Lond. Dub. Tincture ofGuaiac. '
" Take of guaiac powdered, half apound [four ounces, Dub.);proof spirit, two pints. Macerate for fourteen days, (sevendays, Dub.) and filter."
Tinctura Guaiaci officinalis. Edin. Tincture of Guaiac.
" Take of guaiac, in powder, six ounces; alcohol, twopounds and a half. Digest for seven days, and filter throughpaper."
The difference in the proportion of the guaiac in these for-mulas is much to be regretted. It is separated from the alco-hol by the addition of water"; and therefore when this tinctureis to be given in the form of draught, it must be triturated withyolk of egg, or with mucilage, to enable it to combine with wa-ter. The dose is from fy. to fjiij. in any convenient vehicle.
TINCTU'RA GUAI'ACI AMMONIATA.* Lond. Dub.Edin. Ammoniated Tincture of ' Guaiacum.
" Take of guaiac, in powder, four ounces; aromatic spiritof ammonia, one pint and a half. Macerate for fourteen days,(seven days, Edin. Dub.) and filter."
As the ammonia coincides with the operation of guaiac morethan spirit, this tincture is more efficacious as a stimulatingsudorific than the former preparation. Water decomposes it;separating the guaiac in dark curdy flakes. The dose is fromf5j. to fjij. triturated with any mucous or viscid matter.
