The tryptamines are a group of psychotropic hallucinogenic substances that are either natural or synthetic, found in many plants and even in some animals.
This family of substances includes: the dimethyltryptamine DMT, the diethyltryptamine, the Dipropyltryptamine, 4-OH-DMT, 5-OH-DMT, the butofenine, 5-MeO-DMT.
The tryptamines act on serotonin receptors in the central nervous system, derived from the interest of shamanism, and the effect these plants have on the hman mind. The American chemist Alexander Shulgin is known to have studied these effects.
Their chemical structure is of type indole, and they belong to the indolalkylamines, close relatives to the group of lysergic acid chemicles like LSD, and they closely resemble the amino acid tryptophan.
