Pow-Wows; or, Long Lost Friend is a book by John George Hohman published in 1820.
Hohman was a Pennsylvania Dutch healer; the book is a collection of home- and folk-remedies, as well as spells and talismans.
It is a translation of a German original, Der lange verborgene Freund, oder, Getreuer und Christlicher Unterricht für jedermann, enthaltend: wunderbare und probmäßige Mittel und Künste, sowohl für die Menschen als das Vieh ("The Long Hidden Friend,[1] or, True and Christian Instructions for Everyone.
The folk magic tradition called "pow-wowing" takes its name from the title of later editions of this book.
The book gained some notoriety when it was found in the possession of John Blymire, a Pennsylvania man who was charged with murdering a neighbor whom he believed to have put a curse on him.
