Oka Sativa , C. B. It grows in Spain ^ Provence , 
Italy , and other warm Climates. 
Pickled Olives, being eaten before Meals, fays 
Schroder , provoke an Appetite, raife and comfort 
a moift Stomach, and move the Belly. But I have 
here inferted this Fruit on account of its Oil, ex- 
prefled from it when ripe ; which is not only 
ufed in Salads and other Diffies at Table, but is 
of great Service in many Purpofes of Phyflck. It 
loofens the Belly, foftens fharp Humours, lubricates 
and relaxes the Fibres ; is ufeful in Diforders of 
the Bread, in Coughs, Pleurifies, and other Inflam* 
mations; gives Relief in the Colick, Dyfentery 
and Tenefmus ; and helps the Stone and Gravel. 
It has likewife a lovereign Efficacy for preventing 
the Corrofion, and fatal Confequences of many 
Poifons ; as alfo againft Super-purgations, and 
other bad Effedts from acrimonious Purgatives : 
But in,thefe Cafes it ought to be given in large Quan- 
tities by the Mouth, and to be injedled plentifully 
in Clyfters. 
Externally it foftens Tumours and promotes 
Suppuration, and being beaten up with Wine 
makes a good Liniment for Burns. It is ufed in 
many Cerates, Plaifters, and Unguents of the 
Shops. 
The Oleum Omphacinum , which, as many report, 
is exprefled from unripe Olives, feems to be rather 
a mucilaginous Juice than an Oil; becaufe* be- 
fore the Olives are ripe no Oil can be got from 
them. For this Reafon, fome Authors fuppofe 
that the Oleum Omphacinum of the Ancients was 
factitious, (viz.) that it was made by infuflng fome 
aftringent Subftances in common Oil.
