Infusum Valerianae. Lond. Dub. Infusion of Valerian

"Take of valerian, half an ounce; boiling distilled water, a pint. Macerate for two hours, in a lightly-covered vessel, and strain."

Valerian infusion is clear, of a pale brown colour; with the odour of the valerian, and a bitterish, pungent taste. Solutions of nitrate of silver, sulphate of iron, and infusion of yellow cinchona, afford precipitates with this infusion; and are therefore incompatible in formulae with it.

Medical properties and uses. - This is an useful form of giving valerian in hysterical and nervous affections, in which the stomach will not always bear the powder. The dose may be from f jss. to f ij., twice or thrice a day.

Aqua Calcis Composita. Dub. Compound Lime-water

"Take of raspings of guaiacum wood, half a pound; liquorice root, sliced and bruised, an ounce; sassafras bark, bruised, half an ounce; coriander seeds, three drachms; lime-water, six pints. Macerate without heat for two days, and strain."

This is a very inert preparation; and, unless great care be taken to exclude the air completely from the vessel in which it is made, the lime-water will be decomposed.
