This evergreen shrub, cultivated in mountainous regions, acts as a mild stimulant, fostering conversation, enhancing alertness, and reinforcing cultural bonds. Yet behind its traditional use lies a complex story of chemistry, controversy, and changing legal status worldwide. The active compounds in khat cathinone and...

As the most widely recognized and cultivated psychedelic mushroom, Psilocybe cubensis has become synonymous with the modern psychedelic renaissance. This golden-capped, spore-spreading fungus thrives in tropical and subtropical regions around the world, often found in nutrient-rich soils where it decomposes organic matter as part of its natural life cycle. But beyond its ecological role, it holds the key to some of the most promising breakthroughs in mental health and consciousness studies. T...

Deep in the humid, temperate forests of southern Chile grows a small, enigmatic tree known to local Indigenous communities and plant enthusiasts as Latua pubiflora often called árbol de los brujos or “sorcerer’s tree.” As the only species in its genus, this plant holds a unique and potent place in the world of entheogens, particularly within Mapuche and Huilliche traditional medicine and spiritual practice. Latua contains powerful tropane alkaloids similar to those found in datura and brugman...

For over 5,000 years, the small, spineless peyote cactus (Lophophora williamsii) has been a cornerstone of spiritual life for many Indigenous peoples of North America, particularly within the Native American Church. This slow-growing desert plant, containing the psychedelic compound mescaline, offers more than altered perception it provides a pathway to healing, community, and cultural continuity.

While not a classic hallucinogen, the betel palm (Areca catechu) produces a nut chewed by hundreds of millions for its mild yet culturally profound psychoactive effects. Across South Asia, Southeast Asia, and the Pacific, betel nut chewing is a deeply rooted social ritual, a symbol of hospitality, and a traditional medicine but one shadowed by significant health risks. The areca nut contains arecoline, a stimulant alkaloid that affects the central and autonomic nervous systems. When chewed us...

Climbing trellises and winding through gardens worldwide, the humble morning glory (Ipomoea violacea and Turbina corymbosa) conceals a powerful secret: its seeds contain ergine (LSA), a naturally occurring psychedelic compound closely related to LSD. For centuries, Indigenous cultures across Mesoamerica notably the Aztec and Zapotec peoples honored these vines as sacred, using them in divination and spiritual ceremonies under the names ololiuqui or tlitliltzen. When ingested, LSA induces effe...

Steeped in European folklore, feared and revered for millennia, Mandragora officinarum mandrake is one of history’s most legendary psychoactive plants. With its often human-shaped root and notorious mythology, it occupies a singular space where medicine, magic, and danger powerfully converge. Like other nightshades, mandrake contains tropane alkaloids scopolamine, hyoscyamine, and atropine which induce delirium, vivid hallucinations, and deep sedation. In ancient times, it was used as an anes...

Native to the arid coastal mountains of Chile, Lobelia tupa is a striking red-flowered plant deeply woven into the cultural and spiritual practices of the Mapuche people. Known locally as tupa, tabaco del diablo (devil’s tobacco), or tra-tra, this plant has been used for centuries in ceremonial contexts, healing rituals, and as a potent psychoactive agent though its effects and risks place it in a category distinct from more commonly discussed entheogens. Unlike classic psychedelics such as p...

Unlike classic hallucinogens, wild lettuce does not induce vivid visions or profound mystical states but is instead valued for its calming, sedative, and pain-relieving properties, making it a unique member of the world of herbal consciousness modifiers. The milky sap of wild ...

With its pendulous, trumpet-shaped flowers and intoxicating fragrance, Brugmansia known across Latin America as floripondio or “angel’s trumpet” is among the most visually striking and pharmacologically powerful psychoactive plants. Yet behind its enchanting appearance lies a deeply complex and often dangerous profile, one that demands extreme caution, cultural respect, and specialized knowledge. Like its relatives datura and belladonna, Brugmansia contains high levels of tropane alkaloids sc...
