“At the time of the White Dawn;
At the time of the White Dawn,
I arose and went away.
At Blue Nightfall I went away.
I ate the thornapple leaves
And the leaves made me dizzy.
I drank thornapple flowers
And the drink made me stagger…”

~Original Author Unkown
So begins the Pima “Datura Song” first translated in 1901 from a song-poem ritually performed by Tohono O’odham shamans of south-central Arizona and northern Sonora, Mexico. This song was sung to bring success with a hunt, but also in cases of sickness where the characteristic symptoms were vomiting and dizziness (Frank Russell, The Pima Indians, 1908). It illustrates the great significance and nature of datura plants in the oral and sacred traditions of many native cultures.
