esurient
Very greedy or hungry; ravenous; (figuratively) avid, eager.
So that (as I apprehend) theſe Famelick, Eſurient, and Sitient Spirits are not the Ferments product of Concoction in the Ventricle, but only incentives, ordained by nature to render us deſirous of Aliment, to repair the decaying frame of our Body.
Where it comes from
Borrowed from Latin ēsurient, ēsurientem, from ēsuriēns (“hungering”), present participle of ēsuriō (“to be hungry, to hunger for something”), a desiderative verb from edō (“to eat”) (ultimately from Proto-Indo-European *h₁édti (“to eat”)) + -turiō (suffix indicating a desire for an action).
