|It is said that the Indians of the Ecuadoran
highlands smoke this plant, known as shanin, the
effects of which resemble those of Coriaria
thymifolia. The plant is said to give its user "the
feeling of rising into the air or floating weightlessly
away" (Alvear 1971, 23*; Schultes and Hofmann
1992, 53*). Chemical studies to date have not
detected the presence of any alkaloids (Butler at al.
1981; Ott 1993,417*). It is possible, however, that
new diterpenes may be present, as they have been
found in a relative, Petunia patagonica (Speg.)
Millan (Guerreiro et al. 1984). Ketones have alsobeen found in the genus (Elliger et al. 1990).
