"Gelsemium, in No. 60 powder, one hundred grammes [or 3 ounces av., 231 grains], to make one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]. Prepare a Tincture by Type Process P, using a mixture of sixty-five volumes of alcohol and thirty-five volumes of water as the menstruum." U. S.
"Gelsemium Root, in No. 40 powder, 100 grammes; Alcohol (60 per cent.), sufficient to produce 1000 millilitres. Moisten the powder with fifty millilitres of the Alcohol, and complete the percolation process." Br.
This tincture has proven a valuable addition, and will be preferred to the fluidextract for internal administration, as it is safer, and can be used more satisfactorily in extemporaneous combination. The menstruum of the U. S. P., 1890, and VIII and IX processes is weaker than that formerly official, alcohol having been replaced by alcohol diluted with water in the proportion of 65 to 35. For Farr and Wright's method of estimating this tincture, see C. D., 1892, 263.
Dose, from five to twenty minims (0.3-1.3 mils).
