Obs. The Dublin College omitted the cochineal and raisins in their Ph. of 1826, but have restored them in their new one. The order of the London College to stone the raisins is seldom adopted in practice; by which the tincture is rendered unfit to be employed in dispensing prescriptions containing quinine or other alkaloids. When pharmaceutists are too lazy to follow the instructions in their Pharmacopœia, they had better use sultana raisins, which have no stones.—Dose, 1 to 4 fl. dr.; as a cordial and stomachic, but chiefly as an adjunct, for its colour and flavour.
Tincture of Cascaril′la. Syn. Tinctura cascarillæ (B. P., Ph. L., E., & D.), L. Prep. 1. (B. P.) Cascarilla, bruised, 1; proof spirit, 8; macerate 48 hours with 6 of the spirit, agitating occasionally; pack in a percolator, let it drain, and pour on the remainder of the spirit, and, when it ceases to drop, wash the marc, press, filter, and make up 8.—Dose, 1⁄2 to 2 dr.
2. (Ph. L.) Cascarilla, bruised, 5 oz.; proof spirit, 1 quart; macerate for 7 days (14 days—Ph. D.; or percolate—Ph. E.). An excellent tonic and stomachic; chiefly employed as an adjunct to mixtures, &c.—Dose, 1 to 2 fl. dr.
Tincture of Cas′sia. Syn. Tincture cassiæ (Ph. E.), L. Prep. (Ph. E.) Cassia, 31⁄2 oz.; proof spirit, 1 quart; macerate for 7 days, or percolate. Stomachic and carminative.—Dose, 1 to 2 fl. dr.
Tincture of Castor. Syn. Tinctura castorei (B. P., Ph. L. & E.), Tinct. castorei Rossici, L. Prep. 1. (B. P.) Castor, in coarse powder, 1; rectified spirit, 20; macerate seven days, strain, and wash the marc with spirit sufficient to make up to 20.—Dose, 1⁄2 to 1 dr.

Obs. The Dublin College ordered Russian castor in their Ph. of 1826; but the scarcity and high price of that variety, we fear, too often precludes its use. The tincture of the shops is usually made with only 8 oz. of castor to the gall. of proof spirit. Nervine and antispasmodic.—Dose, 20 drops to 2 fl. dr.; in hysteria, epilepsy, &c.
Tincture of Castor (Ammo′′niated). Syn. Elixir fœtidum, Tinctura castorei composita, T. c. ammoniata (Ph. E.), L. Prep. (Ph. E.) Castor, bruised, 21⁄2 oz.; assafœtida, in small fragments, 10 dr.; spirit of ammonia, 1 quart; digest 7 days in a well-closed vessel. Stimulant and antispasmodic.—Dose and uses, as the last. With the addition of 1⁄2 oz. of opium, it forms the Elixir Uterinum, or Elixir Castorei Thebaicum of foreign Pharmacopœias.
Tincture of Castor (Ethereal). Syn. Tinctura castorei ætherea. (P. Cod.) Prep. Castor, in powder, 1 oz.; alcoholised ether (see Ethereal Tinct. of Assafœtida), 10 oz. (by weight).
Tincture of Castor Oil Seeds. Syn. Tinctura ricini. Castor oil seeds bruised are digested with five times their weight of rectified spirit. This tincture is stated to be 4 times the strength of the oil.
