The root known as High John the Conqueror is (supposed to be) the root of Ipomoea jalapa, an Ipomoea species related to the morning glory and the sweet potato. The plant is known in some areas as bindweed or jalap root. It has a pleasant, earthy odour, but it is a strong laxative if taken internally. It is not used for this purpose in folk magic; it is instead used as one of the parts of a mojo bag.
It is typically used in sexual spells of various sorts and it is also considered lucky for gambling. It is likely that the root acquired its sexual magical reputation because, when dried, it resembles the testicles of a dark skinned man. Because of this, when it is employed as an amulet, it is important that the root used be whole and unblemished. Dried pieces and chips of the root are used in formulating oils and washes that are used in other sorts of spells.
Cecil Adams has claimed that John the Conquer root is the root of St. John's wort; however, according to cat yronwode, Cecil Adams is mistaken. St. John's wort root is thin and thread-like root, while John the Conquer root is a tuber. As the blues lyrics below make clear, John the Conquer root is carried by the user, and the spell is cast by rubbing the root, which could not be done with fine root-hairs.

In 1961 Willie Dixon wrote a song called Rub My Root and in 1964 it was recorded by Muddy Waters under the title My John the Conquer Root.
The first verse goes:
My pistol may snap, my mojo is frail
But i rub my root, my luck will never fail
When i rub my root, my John the Conquer root
Aww, you know there ain't nothin' she can do, Lord,
I rub my John the Conquer root
In 1954, Muddy Waters recorded a very popular version of Willie Dixon's (I'm Your) Hoochie Coochie Man song with an additional verse mentioning John the Conquer root:
I got a black cat bone, I got a mojo too,
I got a John the Conquer root, I'm gonna mess with you,
I'm gonna make you girls lead me by my hand,
Then the world will know the hoochie coochie man.
In 1971, Dr John (Mac Rebennack) recorded a song called 'Black John the Conqueror' on his 'Sun Moon & Herbs' album which describes some of the legends surrounding the folk hero and as well as the powers of the herb.
