"Buchu, in No. 40 powder, one thousand grammes [or 35 ounces av., 120 grains]. Prepare a Fluidextract by Type Process A, using alcohol as the menstruum." U. S.
The menstruum selected for this fluidextract has been alcohol, although experience has shown that with the weaker alcohol used in the U. S. P. VIII formula it was possible to percolate buchu leaves satisfactorily. We prefer as a menstruum that of the U. S. P. VIII, i.e., alcohol 3, water 1.
This fluidextract is of a dark green color, and shows in a high degree the sensible properties of the leaves. It acquires the odor of mint when long kept, showing that some change takes place in its volatile oil. This fluidextract affords the best means at our command for the exhibition of buchu.
Dose, thirty minims to a fluidrachm (1.8-3.75 mils), three to five times a day.
