Euclea, from the Greek eukleia meaning "glory and fame", denotes a group of flowering plants in the Ebenaceae or ebony family. They were described as a genus by Linnaeus in 1774. The genus includes evergreen trees and shrubs, native to Africa, the Comoro Islands and Arabia. Several species are used for timber, producing a hard, dark heartwood timber similar to ebony.
An oneirogen, from the Greek ὄνειρος óneiros meaning "dream" and gen "to create", is that which produces or enhances dream-like states of consciousness. This is characterized by an immersive dream state similar to REM sleep, which can range from realistic to alien or abstract. Many dream-enhancing plants such as dream herb and African dream herb, as well as the hallucinogenic diviner's sage, have been used for thousands of years in a form of divination through dreams, called oneiromancy, in which practitioners seek to receive psychic or prophetic information during dream states. The term oneirogen commonly describes a wide array of psychoactive plants and chemicals ranging from normal dream enhancers to intense dissociative or deliriant drugs. Effects experienced with the use of oneirogens may include microsleep, hypnagogia, fugue states, rapid eye movement sleep (REM), hypnic jerks, lucid dreams, and out-of-body experiences. Some oneirogenic substances are said to have little to no effect on waking consciousness, and will not exhibit their effects until the user falls into a natural sleep state.

Salvia divinorum is a plant species with transient psychoactive properties when its leaves are consumed by chewing, smoking, or as a tea. The leaves contain opioid-like compounds that induce hallucinations. Because the plant has not been well-studied in high-quality clinical research, little is known about its toxicology, adverse effects, or safety over long-term consumption. Its native habitat is cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady, moist locations. The plant grows to over a meter high, has hollow square stems like others in the mint family Lamiaceae, large leaves, and occasional white flowers with violet calyxes. Botanists have not determined whether Salvia divinorum is a cultigen or a hybrid because native plants reproduce vegetatively and rarely produce viable seed.

Euclea crispa, commonly known as the blue guarri, is an Afrotropical plant species of the family Ebenaceae. The hardy and evergreen plants may form a dense stand of shrubs, or grow to tree size. It is widespread and common in the interior regions of southern Africa, and occurs northward to the tropics. Though some are present near the South African south and east coasts, they generally occur at middle to high altitudes. It is readily recognizable from its much-branched structure and dull bluish foliage colour. Those bearing lanceolate leaves may however resemble the Wild olive, another common species of the interior plateaus.
