Cordiale Rubi Fructus (N. F.)—Blackberry Cordial.
Formulary number: 28.
Preparation.—"Blackberry juice, eighteen hundred and seventy-five cubic centimeters (1875 Cc.) [63 fl℥, 192♏]; cinnamon, in No. 40 powder, one hundred grammes (100 Gm.) [3 ozs. av., 231 grs.]; cloves, in No. 40 powder, one hundred grammes (100 Gm.) [3 ozs. av., 231 grs.]; nutmeg, in No. 40 powder, twenty-five grammes (25 Gm.) [386 grs.]; diluted alcohol (U. S. P.), a sufficient quantity; syrup (U. S. P.), eighteen hundred and seventy-five cubic centimeters (1875 Cc.) [63 fl℥, 192♏]. Percolate the powdered spices with diluted alcohol to obtain twelve hundred and fifty cubic centimeters (1250 Cc.) [42 fl℥, 128♏] of tincture, and add to this the blackberry juice. Then add thirty grammes (30 Gm.) [1 oz. av., 25 grs.] of purified talcum, set the mixture aside for 24 hours, occasionally shaking, and filter. Wash the filter with sufficient diluted alcohol to obtain thirty-one hundred and twenty-five cubic centimeters (3125 Cc.) [105 fl℥, 321♏] of filtrate; lastly add the syrup, and mix well"—(Nat. Form.).
Prof. Maisch used precipitated calcium carbonate instead of talcum, and suggests that as the syrup is apt to become turbid after standing, it should be filtered before dispensing, but in our opinion this should not be done. We have known blackberry cordial to become a gelatinous magma.
