The authors used Ultra-High Performance Liquid Chromatography and High Resolution Mass Spectroscopy to test for the presence of the alkaloids atropine, scopolamine, and ephedrine. Atropine and scopolamine are naturally found in the nightshade plant family, and can induce delirium, hallucinations, and altered sensory perception. Ephedrine is a stimulant derived from certain species of shrubs and pines, which can increase excitement, alertness, and physical activity. The authors detected scopolamine, ephedrine and atropine in three replicated hair samples.
The authors suggest that the presence of these alkaloids may have been due to consumption of some nightshade plants, such as mandrake (Mandragora autumnalis), henbane (Hyoscyamus albus) or thorn apple (Datura stramonium), and joint pine (Ephedra fragilis). The authors suggest that these drug plants may have been used as part of ritual ceremonies performed by a shaman.
