Sinicuichi
Sinicuichi (Heimia salicifolia) is a perennial shrub of the loosestrife family, Lythraceae, native to the Americas from the southwestern United States through Mexico and Central America to Argentina. It grows to roughly 1.5 meters with narrow leaves and yellow flowers. The leaves have been used orally for shamanic purposes by indigenous peoples of Central America and Mexico. Its effects are tentatively classed as psychedelic and reported to be primarily auditory, and its major active compound remains unidentified.
