Most familiar to me from Edgar Allan Poe's The Raven, where the deranged narrator asks this to the bird:
“Prophet!” said I, “thing of evil!—prophet still, if bird or devil!—
Whether Tempter sent, or whether tempest tossed thee here ashore,
Desolate yet all undaunted, on this desert land enchanted—
On this home by Horror haunted—tell me truly, I implore—
Is there—*is* there balm in Gilead?—tell me—tell me, I implore!”
Quoth the Raven “Nevermore.”
And most familiar to me as the capital of the Barony of New Canaan in Stephen King's The Dark Tower. Albeit no balm in this story (that I recall). https://darktower.fandom.com/wiki/Gilead
