This site is not intended as medical advice. You couldn't follow the advice anyway, since Hamlin's Wizard Oil has not been sold for many decades.
This site is a piece of americana, a trip back to the days of traveling snake oil salesmen and their miracle cures.
Hamlin's Wizard Oil was a real product. You can still buy the empty bottles online, for example on eBay. (Hint: the bottles with labels still attached are the most valuable).
Hamlin's sponsored singing troupes known as the Wizard Oil Concert Companies. The company distributed songbooks with the words to the songs sung in concert. These songbooks were liberally laced with instructions to treat myriad diseases with Hamlin's Wizard Oil. The content of this Web site is from one such book, entitled "Special Edition, The Old Songs, Published at Request of Many Old Friends".
