⭐ Core Definition: Echinopsis

Echinopsis is a genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. As of November 2025, Plants of the World Online used a broad circumscription of the genus, resulting in about 80 accepted species, ranging from large and treelike types to small globose cacti. The name derives from echinos hedgehog or sea urchin, and opsis appearance, a reference to these plants' dense coverings of spines.

They are remarkable for the great size, length of tube, and beauty of their flowers, borne upon generally small and dumpy stems.

👉 Echinopsis in the context of Mescaline

Mescaline, also known as mescalin or mezcalin, and in chemical terms 3,4,5-trimethoxyphenethylamine, is a naturally occurring psychedelic protoalkaloid of the substituted phenethylamine class, found in cacti like peyote (Lophophora williamsii) and San Pedro (certain species of the genus Echinopsis) and known for its serotonergic hallucinogenic effects.

Mescaline is typically taken orally and used recreationally, spiritually, and medically, with psychedelic effects occurring at doses from 100 to 1,000 mg, including microdosing below 75 mg, and it can be consumed in pure form or via mescaline-containing cacti. Mescaline induces a psychedelic experience characterized by vivid visual patterns, altered perception of time and self, synesthesia, and spiritual effects, with an onset of 0.5 to 0.9 hours and a duration that increases with dose, ranging from about 6 to 14 hours. Ketanserin blocks mescaline’s psychoactive effects, and while it's unclear if mescaline is metabolized by monoamine oxidase enzymes, preliminary evidence suggests harmala alkaloids may potentiate its effects.

Echinopsis in the context of Echinocereus

Echinocereus is a genus of ribbed, usually small to medium-sized, cylindrical shaped cacti, comprising about 70 species native to the southern United States and Mexico in very sunny, rocky places. Usually the flowers are large and the fruit edible.

The name comes from the Ancient Greek ἐχῖνος (echinos), meaning "sea urchin", and the Latin cereus meaning "candle". They are sometimes known as hedgehog cacti, a term also used for the Pediocactus and Echinopsis.
