It is, in the words of the old formula, Curare, cito, tuto, et jucunde, to cure quickly, safely, and pleasantly.
The researches of his pupil, Claude Bernard, on curare, were equally exact and logical, and have served as the model for many subsequent investigations.
There are therefore in most prescriptions (i) a basis or chief ingredient intended to cure (curare), (2) an adjuvant to assist its action and make it cure quickly (cito), (3) a corrective to prevent or lessen any undesirable effect (tuto), and (4) a vehicle or excipient to make it suitable for administration and pleasant to the patient (jucunde).
