Emergency Room Visits Yearly: Unknown

Mandatory Minimum Sentence: None

Mechanism of Action: Increases Serotonin when combined with an MAOI


Psychotria carthagensis, or amyruca, is one of the admixtures that can be used to make the entheogenic brew ayahuasca. It is traditionally combined with Banisteriopsis caapi. The leaves of Psychotria carthagensis contain DMT. According to Ott (1994), there is 0.2% average DMT in dried leaves.

Psychotria carthagensis is currently legal to buy, sell, and possess in the United States.


General MAOI warnings. When ingested orally, MAOIs inhibit the catabolism of dietary amines. Sufficient intestinal MAO-A inhibition can lead to hypertensive crisis, when foods containing tyramine are consumed (so-called “cheese syndrome”), or hyperserotonemia if foods containing tryptophan are consumed. The amount required to cause a reaction exhibits great individual variation and depends on the degree of inhibition, which in turn depends on dosage and selectivity.

The exact mechanism by which tyramine causes a hypertensive reaction is not well understood, but it is assumed that tyramine displaces norepinephrine from the storage vesicles. This may trigger a cascade in which excessive amounts of norepinephrine can lead to a hypertensive crisis. Another theory suggests that proliferation and accumulation of catecholamines causes hypertensive crises.
