Helenium
Also known as Common sneezeweed, Autumn sneezeweed, Swamp sunflower, Wild sunflower, Sneezewort (regional, though this name more properly belongs to Achillea ptarmica), Sneezewort.
Helenium autumnale, the common sneezeweed, is a North American perennial of wet meadows and streambanks in the Asteraceae family, bearing yellow daisy-like flower heads in late summer and autumn. Its dried and powdered flowers were used by nineteenth century eclectic physicians as an errhine, a substance snuffed to provoke sneezing and clear the sinuses, much as older snuffs were used for head colds. The plant's common name reflects this historical use rather than any resemblance to the unrelated sneezewort, Achillea ptarmica, which shares the folk name in some regions.

In eclectic practice, powdered sneezeweed flower was insufflated in small pinches to trigger sneezing, on the theory that this reflex helped loosen and expel thick nasal secretions in chronic catarrh and sinus congestion, particularly when the head felt dull and heavy and ordinary decongestant measures had failed.
