In the eighteenth century, dittany gained notice in Europe for its efficacy in treating worms and infections. A tincture of dittany cut with wine was also used to treat epilepsy. William Woodville reports in his three-volume Medical Botany that the plant could often be seen adorning the borders of flower gardens, emitting a strong bituminous odor. Wizards, follow your nose: as term begins, and you make your way to platform 9-and-3/4, you'll do well to nab this odiferous plant from Woodville's former garden, located in King's Cross just yards away from the Hogwarts Express.
