"Kava Rhizome, in No. 20 powder, 1000 grammes; Alcohol (90 per cent.), a sufficient quantity; Alcohol (45 per cent.), a sufficient quantity. Mix the powdered Kava Rhizome with two thousand millilitres of the Alcohol (90 per cent.); set aside in a closed vessel for forty-eight hours; transfer to a percolator and percolate slowly, reserving the first seven hundred and fifty millilitres of the percolate. Continue the percolation, adding the Alcohol (45 per cent.) until the powder is exhausted; recover most of the alcohol from this percolate by distillation; evaporate the residue at a temperature below 80° C. (176° F.) to a soft extract, and dissolve this in the reserved percolate; add sufficient of the Alcohol (90 per cent.) to produce one thousand millilitres of the Liquid Extract." Br.
