Tinctura Opii camphorata, sive Elixir paregoricum Anglorum, Edin. Dub. Camphorated Tincture of Opium, or Paregoric Elixir.

"Take of camphor, two scruples; hard purified opium in powder, benzoic acid, of each a drachm.; proof spirit, two pints. Digest for .seven (ten, Dub.) days, then filter."

Syn. Teinture camphree d'Opium (F.), Opiumstinktur rait Benzoe (G.).

Half a fluid ounce of this tincture contains nearly a grain of opium. The tincture differs little from that which has been long known under the titles Paregoric Elixir and Asthmatic Elixir. It is a useful anodyne in chronic asthma, hooping-cough, and chronic bronchitis, after the inflammatory symptoms have abated; in which it contributes to allay the tickling which induces the frequent cough. The dose is from f 3 j. to f 3 ij. occasionally in the above cases, using after it the inhaler; and f 3 iij. in cases where quiet, rather than sleep, is required.

1 The change of name here imposed appears to us to be more likely to produce errors than the old name; and it is directly opposed to the principles of nomenclature adopted by the College.

Tinctura Cantharidis. Lond. Tincture of Blistering Fly

"Take of blistering flies, bruised, four drachms; proof spirit, two pints. Macerate for fourteen days, and filter."

Tinctura Cantharidis vesicatoriae, Edin. Tincture of Blistering Fly.

"Take of blistering flies, bruised, a drachm; proof spirit, a pound. Digest for seven days, and filter through paper."

Tinctura Cantharidis, Dub. Tincture of Blistering Fly.

"Take of blistering flies in powder, two drachms; proof spirit, a pound and a half Digest for seven days, then strain."

Syn. Teinture de Cantharides (.F.), Cantharidentinktur ( G.), Tintura di Can-taridi (I.).

Proof spirit extracts the active matter of blistering flies, and is a more convenient form for exhibiting it internally than in substance.

This tincture is useful in gleets, fluor albus, incontinence of urine, and in some cutaneous eruptions. The dose is from

x. to f 3 j. given in some demulcent infusion. As an external application it is efficaciously employed in conjunction with soap or camphor liniment, as an embrocation against rheumatic pains; and I have found that a rag moistened with it is a useful application in spontaneous mortification of the extremities; and to frost-bitten parts.

Tinctura Capsici. Lond. Dub. Tincture of Capsicum

"Take of capsicum, ten drachms; proof spirit, two pints. Macerate for fourteen days, and filter."

This is a convenient form for exhibiting capsicum in tympanitis, cynanche maligna, the low stage of typhus; and in gargles. The dose is xij. to f 3 ss. A mixture of f 3 ij. with half a pint of water answers instead of the capsicum gargle.
