Infusions of the leaves were used by by Native Americans as an emetic. A poultice of them was applied to inflamed throat glands, cuts, bruises, swellings and other wounds, and for removing the pus from scrofulous sores or boils. http://herb.umd.umich.edu/herb/search.pl?searchstring=Nicotiana+glauca
β-pyridyl-α'-piperidine, called anabasine, isomeric with nicotine, was shown to be the main alkaloid in N.glauca (and a minor alkaloid in N.tabacum).
