Re'em

The Re'em is native to the wilds of Northern America and the Far East. This extremly rare golden fured giant Ox's blood gives immense strength to the drinker. However, since demand far exceeds supply, Re'em blood can only be found on the open market rarley.

J.k. Rowling borrowed the idea of the Re'em from ancient writings, though she created her own description of it.

Re'em is Hebrew for "wild Ox."
