Tincture of krameria was deleted from the U. S. P. IX, but retained in the Br. Pharm. 1914 and added to the N. F. IV. The British tincture closely resembles the former U. S. P. preparation.
"Krameria Root, in No. 40 powder, 200 grammes; Alcohol (60 per cent.), sufficient to produce 1000 millilitres. Moisten the powder with one hundred millilitres of the Alcohol, and complete the percolation process." Br.
It is stated that the tincture made from Para rhatany furnishes a clear solution on the addition of water, while that from Peruvian root yields a turbid mixture.
The same precaution should be observed in keeping this tincture as is recommended for tincture of kino. It is a good preparation in cases which admit of the use of small quantities of alcohol.
Dose, one or two fluidrachms (3.75 or 7.5 mils).
