Effects of the kourbash:

Ve-ry rarely. Let me be fair. I've never seen a man die under the lash, but gangrene may set up if the kourbash has been pickled."

"Pickled in what?" All the table was still and interested.

"In copperas, of course. Didn't you know that" said the Inspector.

"Thank God I didn't." The large man sputtered visibly."

I'm pretty sure copperas is copper sulfate, which should
kill bacteria on the kourbash. I think a "not" was omitted.
