Essence of Ro′ses. Syn. Essentia rosæ (odorata), L. Prep. 1. Attar of roses (genuine), 2 dr.; alcohol, 1 pint; agitate frequently until they unite.
2. Attar of roses, 1 oz.; rectified spirit, 1 gall.; mix in a close vessel, and assist the solution by placing it in a bath of hot water. (See Essence of Musk.) As soon as the spirit gets warm, take it from the water and shake it till quite cold; the next day filter.—Obs. Unless the spirit of wine is of more than the common strength, it will not retain the whole of the otto in solution in very cold weather.
3. To each pint of either of the preceding, add, of oil of bergamotte, 30 drops; neroli and essence of musk, of each 20 drops.
4. Petals of roses, 3 lbs., digest in spirit of wine, 5 quarts, for 24 hours; distil to dryness in a water bath; digest the distilled spirit on 2 lbs. of fresh rose petals, as before, and repeat the whole process of maceration and distillation, a third, fourth, fifth, and sixth time, or oftener, the last time only drawing over 1 gall., which is the essence. Each of the above is very superior. The last has a peculiar delicacy of flavour, when the spirit used to make it is pure.
Essence of Roses (Red). Syn. Essentia rosæ (rubra), Tinctura e. concentrata, L. Prep. From rose leaves, 1 lb.; proof spirit, 1 gall.; digest for 14 days, press, strain, add concentrated acetic acid, 21⁄2 fl. dr.; mix well, and the next day filter. Used to make extemporaneous SYRUP and HONEY OF ROSES, &c. Smells, colours, and tastes strongly of the flower. Concentrated infusion of roses is sold under the same name.

Essence of Sarsaparil′la. Syn. Concentrated essence of sarsaparilla; Essentia sarsæ; E. sarsaparillæ; L. Prep. 1. Sarsaparilla root (best red Jamaica), 23⁄4 lbs., is carefully decorticated, the bark reduced to coarse powder, and digested for a week or 10 days in sherry, 3⁄4 pint, and rectified spirit, 1⁄4 pint, with frequent agitation; after which the essence is expressed, and in a week the clear portion is decanted from the sediment. A very elegant preparation. 1⁄2 fl. dr. added to 7 fl. dr. of water forms 1 fl. oz. of a solution of equal strength to decoction of sarsaparilla of the Ph. L. Every fl. oz. represents the active principles of 2 oz. (= 2 oz. 85 gr. avoir.) of sarsaparilla root. In other words, it is twice
as strong as the root, and 16 times as strong as the decoction.
2. Alcoholic extract of sarsaparilla, 7 oz.; sherry, 3⁄4 pint; rectified spirit, 1⁄4 pint; dissolve and filter. Strength as the last.
