Solandra /soʊˈlændrə/[1] is a genus of flowering plants in the nightshade family, Solanaceae.

Solandra grandiflora was once (and likely still is) used by the Huichol of Mexico and other tribes of the region where it is known by the name "kieli" or "kieri" with some archaeological evidence supporting the theory that its use as a hallucinogen predates that of peyote (Lophophora williamsii).

A tea from the branches and more so from the roots and fruits is used as an inebriant in native traditions.

The alkaloids present include atropine, noratropine, hyoscyamine, and tropine with about 0.15% overall content in the leaves.
