Nothing makes ayahuasca a nickname and b.caapi a name, the name ayahuasca is more ancient and definitely relates more to the true nature of _________ than b.caapi

The scientific name for the plant is Banisteriopsis Caapi
The "common name" is: ayahuasca, yagé, cipó, vegetal, natem, shori, mihi, etc...
(The word ayahuasca refers to the B. Caapi vine, as well as a brew made from just B. Caapi, and also refers to brews made with psychotria viridis / diplopterys cabrerana, B. Caapi and other admixture plants.
Ayahuasca is a quechua word, and serves as a good title, however I don't understand why "ayahuasca" was preferred over any of the other common names from other tribal peoples...
The reason why we use Latin names is because this way it doesn't matter what country or region you live in or what language you speak, the plant receives a set name that is the same EVERYWHERE and for everyone...
So, technically, the Latin name is always the scientifically correct and preferred nomenclature, it's also the preferred nomenclature if you wish to be understood by people from other regions of the globe or people who speak other languages.
