Psychotria carthagenensis, also known as amyruca, is a South American rainforest understory shrub from the coffee family, Rubiaceae. It grows from the tropics of South America to Mexico.{{cite web|url=http://apps.kew.org/wcsp/|title=WCSP |work= World Checklist of Selected Plant Families|access-date=2 April 2010}}

The plant is used in the preparation of the ayahuasca decoction.{{Cite thesis |title=Monoamine oxidase inhibitors in Amazonian hallucinogenic plants : ethnobotanical, phytochemical, and pharmacological investigations |url=https://open.library.ubc.ca/soa/cIRcle/collections/ubctheses/831/items/1.0096656 |publisher=University of British Columbia |date=1984 |first=Dennis Jon |last=McKenna}}

Pharmacological studies

A study in 1972 based in gas chromatography–mass spectrometry method determined the presence of the alkaloids N,N-Dimethyltryptamine (DMT), N-monomethyltryptamine (MMT) and 2-methyl-1,2,3,4-Tetrahydro-β-carboline (MTHC) in the leaves.{{Cite journal |last1=Rivier |first1=Laurent |last2=Lindgren |first2=Jan-Erik |date=1972 |title="Ayahuasca," the South American Hallucinogenic Drink: An Ethnobotanical and Chemical Investigation |url=https://www.jstor.org/stable/4253328 |journal=Economic Botany |volume=26 |issue=2 |pages=101–129 |doi=10.1007/BF02860772 |jstor=4253328 |bibcode=1972EcBot..26..101R |issn=0013-0001}}

In a study in 1994 on ethanol extracts of the leaves showed negative results for the presence of alkaloids.{{cite journal|title= Absence of alkaloids in Psychotria carthagenensis Jacq.

Hybridisation

Psychotria carthagenensis has been hybridised with the closely related P. viridis, by Australian nurseryman and scientist Darren Williams. The cultivar Nexus was created in 2008, sold by the nursery Herbalistics, resulting in a plant with greater cold tolerance, increased growth rate.
