4. Spiritus Ammonias Aromaticus

(See Ammoa. Sp. Arom.) Bote of Liquor AmmoniAe, (not Fortior) ex. - exxx. properly diluted. The dose of Liq. Ammon. Port is one-third of that amount.

Med. Prop. and Action. The vapour, particularly of the stronger solution, is powerfully irritant to the mucous membranes of the air-passages, the nostrils, and the conjunctiva. When inhaled, or taken internally, largely diluted, it proves an excellent stimulant and restorative in syncope, in hysteria, in the collapse of Cholera, and in all cases where the vital powers are much depressed. It is one of the best antidotes in poisoning by Hydrocyanic Acid, Digitalis, and other sedative poisons. It possesses powerful antacid properties. When larger doses of the solutions are swallowed, they act as violent corrosive poisons. The Carbonate of Ammonia may be substituted, in many cases with advantage, for the Liq. Ammonia}. As a vesicant and counter-irritant, Liq. AmmoniAe is a valuable and efficacious application. It is the basis of Dr. Granville's formulAe. A simple mode of applying it is as follows: - Fill the lid of a wooden pill-box with circular pieces of lint or linen till they are above the level of the rim. Pour the strong Liquor on the lint so as to saturate the folds; the box is then to be instantly inverted over the affected part, and held on with firm but gentle pressure. At first it feels like a piece of ice; in a minute or less, a sense of heat and tingling is experienced; then a burning heat, and in a few minutes (from two to five), a blister is raised.* M. Gondret's vesicating ointment, commonly employed in France, is composed of Lard j., Oil of Almonds fss., Liq. Ammon. Fort. fv. The two first are melted together with a gentle heat, then poured into a wide-mouthed bottle, and the Ammonia added. It should be constantly agitated till it becomes cold. Counter-irritation, thus produced, is stated to be very successful in relieving the pain in neuralgic, convulsive, and spasmodic diseases. It is preferable to Cantharides as a vesicatory, both on account of the rapidity of its operation and its not affecting the urinary organs.

Incompatibles. All Acids and Salines, Solutions of all Earths, except Lime and Barytes.

196. Therapeutic Uses

Amenorrha and Chlorosis. Dr. Ashwell states that he has found a mixture of f3j. of Liq. Ammon. in Oj. of Milk, injected into the vagina daily, very efficacious in Chlorosis. It has also been successfully employed, by Lavagna in Amenorrha, and it has been favourably spoken of by Dr. Blundell.
