Psychotria carthagenensis – Sameruca (plant)

5.0 (1 review)




Psychotria carthagenensis is used in South America as an additive to Ayahuasca brews (Plants of the Gods, Schultes and Hofmann, 1992). Faster and easier to grow than Psychotria viridis and used in the same manner. Rubiaceae family. Several reports have failed to find any alkaloids present in P. carthagenensis but they have shown in animal studies that extracts have an effect on the CNS.

Care and Cultivation of Psychotria carthagenensis

Psychotria carthagenensis are relatively fast growing plants that flower after 1-2 years. They prefer a part shade position that is moist and well drained; think of the rainforest understory where they live. More tolerant of cold conditions than Psychotria viridis. Fertilise moderately over the warmer months and provide adequate water.

Psychotria viridis or ‘Nexus’ can be grafted onto this species for faster growth and more cold tolerance.

    My carth had no problems at all adjusting to the climate, had a nice thick stem and lots of leaves. Much more forgiving than viridis in my cool climate.
