"Stramonium, in No. 60 powder, one hundred grammes [or 3 ounces av., 231 grains], to make about one thousand mils [or 33 fluid-ounces, 6 ½ fluidrachms]. Prepare a Tincture by Type Process P, as modified for assayed tinctures, using- diluted alcohol as the menstruum and adjusting the volume of the finished Tincture so that each one hundred mils contains 0.025 Gm. of the total alkaloids of stramonium.
"Stramonium Leaves, in No. 20 powder, 200 grammes; Alcohol (45 per cent.), sufficient to produce 1000 millilitres. Moisten the powder with two hundred millilitres of the Alcohol, and complete the percolation process." Br.
This tincture is now made from Stramonium leaves instead of the seeds as directed by the U. S. P. 1890, and the strength made 10 Gm. of drug, per 100 mils, instead of 15 Gm., as in the U. S. P. 1890, and an assay has been appended. The Br. Pharm. 1898 increased the strength of this preparation 60 per cent., but changed the form of the drug from seeds to leaves. The British tincture is now double the strength of the U. S. P. tincture.
Dose, from ten to twenty minims (0.6-1.3 mils); of the British tincture, five to ten minims (0.3-0.6 mil).
