Composition
There are claims that Hamlin's Wizard Oil and Kickapoo Indian Oil are both based on "Flagg's Instantaneous Relief", the concoction of Prof. E. H. Flagg. What-ever the truth may be, most recipes proposed for Hamlin's oil agree that the main constituent is alcohol, combined with oils of sassafras and clove, camphor, and often aqua ammonia and turpentine, potentially in addition to other tinctures.

Oleson's "Secret nostrums and systems of medicine" (1890), citing a Dr. Douglas, lists the basic formula for Hamlin's Wizard Oil as follows: "Alcohol (1 pt), gum camphor (1 oz), oil sassafras (&frac12; oz), tincture of myrrh (&frac12; oz), tincture of capsicum (&frac12; oz), and chlorofrom (&frac12; oz)."

Alternately, "Dr. Chase's New Receipt Book" (1889) gives his recipe for Hamlin's Wizard Oil as: "Spirits of camphor, &frac12; oz.; aqua ammonia, &frac14; oz.; oil of sassafras, &frac14; oz.; oil of cloves, 1 dr.; chloroform, 2 drs.; spirits of turpentine, 3 drs.; dilute alcohol, 3 drs."
