"Cannabis, in No. 30 powder, one thousand grammes [or 35 ounces av., 120 grains]. Prepare a Fluidextract by Type Process A, using alcohol as the menstruum. After dissolving the soft extract in the reserve liquid, assay a portion as directed below and from the result thus obtained adjust the volume of the finished Fluidextract to conform to the above biological standard.

"Assay.—Proceed as directed under Cannabis and also under Biological Assays," U. S.

Uses.—The fluidextract of cannabis represents the therapeutic virtues of that drug in a convenient form. The smallness of the dose is an advantage over the tincture and many believe that the extract is injured by the evaporation. Unfortunately the fluidextract, even when properly made, does not retain its powers and after a year is almost worthless. For this reason the commercial samples vary so greatly in power that it is impossible to assign the proper dose. The only satisfactory way to use it is to start in with doses of one or two minims, increasing each day until some effect is obtained.

Dose, one to four minims (0.06-0.25 mil).
