Indian physic

Blennerhassett was convoyed to the depths of the island forest, where the strangely assorted pair conversed intimately on the virtues of pleurisy-root, Indian physic and columbo.

This plant—I'm taking the whole thing, root and stem, to show him how it grows—is the genuine Indian physic; I got it right by a big rotten log in Putnam's woods.

Mr. Buck went down by the creek and dug some roots he called Indian Physic, then steeped them until the infusion seemed as black as molasses, and, when cool told me to take a swallow every fifteen minutes for an hour, then half as much for another hour as long as I could keep it down.
