A defined compound
Modern reference databases identify harmine by a specific chemical structure. “Telepathine” is retained as a historical name, not a separate active ingredient.

What is
telepathine?
An early name for harmine—and a portal into chemistry, botanical knowledge, strange reports, and the discipline of separating evidence from interpretation.
The short answer
Telepathine is a historical synonym for harmine.
Harmine is a β-carboline alkaloid reported in plants including Banisteriopsis caapi andPeganum harmala. The arresting old name came from an era of competing alkaloid names and reports interpreted through ideas about telepathy. The name documents that history; it does not prove paranormal communication.
A culturally loaded name
The word carries early scientific encounters with Indigenous plant knowledge, regional names, and extraordinary reported experiences.

Related does not mean identical.
Harmine, harmaline, “harmala,” and tetrahydroharmine are often blurred together. Some are individual compounds; one can name a broader family or plant. Those differences matter when reading research or evaluating a product claim.
