"Triticum, finely cut, one thousand grammes [or 35 ounces av., 120 grains]; Alcohol, two hundred mils [or 6 fluidounces, 366 minims]. Prepare a Fluidextract by Type Process D, evaporate the aqueous percolate to eight hundred mils [or 27 fluidounces, 24 minims] and when cold add the alcohol and, if necessary, sufficient water to make the product measure one thousand mils [or 33 fluidounces, 6 ½ fluidrachms]." U. S.
"Couch Grass, cut small, 1000 grammes; Distilled Water, boiling, 10,000 millilitres; Alcohol (90 per cent.), sufficient to produce 1000 millilitres. Boil the Couch Grass with the Distilled Water for thirty minutes; strain; evaporate to seven hundred and fifty millilitres; cool, and add sufficient of the Alcohol to produce the required volume; filter." Br.

In making this fluidextract in warm weather, it is advisable to commence evaporating the percolate before the drug is exhausted, or fermentation may set in; triticum contains fermentable sugars, and diluted aqueous solutions do not keep well.
This fluidextract represents whatever virtues triticum possesses. The German Pharmacopoeia formerly directed an Extractum Graminis, by digesting 1 part of Triticum with 6 parts of hot water, for six hours, straining, evaporating to a syrup, mixing 1 part of this extract with 4 parts of cold distilled water, filtering, and evaporating to an extract. The fluidextract is preferable, as the excessive use of heat is avoided.
Dose, from three to six fluidrachms (11.25-22.5 mils).
