decoction or infusion, allowing to every six pints of water one 
ounce of fresh roots bruised; they boil it on a slow fire in a 
glazed pot, covered, until the liquid is diminished one half; 
and without straining, they take out, after it has settled, the 
quantity. to be used each time, either hot or cold, as may be 
most suitable to the patient. In the morning fasting they are 
accustomed to take the decoction warm, sweetened with a little 
sugar ; but in the-course of the day they drink it ad libitum; 
cold and not sweetened, in syphilis, or for bruises, contusions, 
and falls, to: prevent the probable results of such accidents ; as 
the Faculty say that this specific operates as a powerful deobstru- 
ent, solvent, balsamie; and diuretic remedy. The natives of Peru, 
and even the Faculty themselves, affirm, that much sediment is 
_ observed in the urine-of persons who have used the decoction of 
the Calaguala. To employ it green as well as dry, it is not ne- 
cessary to. boil it as is commonly done ; it is sufficient only to 
bruise and infuse it in cold water for a few hours, as it readily 
yields its bitter and saline extract, especially if care be taken to 
shake the-bottle or vessel in. which the mfusion. is:-made. The 
of butter with three, pints of the decoction; and in other cases, equal parts are taken of the 
decoction and asses’ milk, or, in defect of that, cows’ milk, with great benefit to patients. 
The Professor adds the various preparations used’ of the Calaguala; the regimen and mes 
thod of administering ;-the results obtained on the analysis which he made of it; the dose; 
and lastly the experiments.and observations, made with great success on different subjects,. 
with the Calaguala, communicated by Don Juan Felix de Andrade, and dispensed by the me- — 
thod of Dr, Peralta, who, according to Bravo, ‘was the first | saniard who promulgated at 
Court. the admirable virtues of the genuine Calaguala, which was probably. that obtained by: 
Bravo and Andrade from Bartbolomew de Andrade, who stated to Professor Bravo that he . 
had collected it with his own hands in the hills of Cuzco, as of a superior quality to that of 
Quito and the other provinces: of Peru, In the Appendix to his Dissertation he inserts the 
operation for separating the essential salt, as he calls it, of the Calaguala, having used the. 
hydraulic machine constructed by Count de la Garaye; and he.affirms that the use of this salt, 
or rather saline extract, produces better and stronger effects than the ptisan and other —_ 
of administering the Calaguala, .
