Mix the glycerin with 90 (18 fluid ounces) of the alcohol, percolate the drug with the mixture, and continue the percolation with more alcohol until exhausted. Reserve the first 80 (16 fluid ounces) of percolate; concentrate the subsequent percolate to a soft extract, dissolve this in the reserved portion, and add sufficient of the alcohol to make up to the required volume. Liquid extract of krameria is liable to gelatinise on keeping, unless prepared by a process similar to that recommended in the case of Tinctura Kino.
Dose.—2 to 4 mils (½ to 1 fluid drachm).
