Ayahuasca (ayawaska pronounced [ajaˈwaska] in the Quechua language) is any of various psychoactive infusions or decoctions prepared from the Banisteriopsis spp. vine, usually mixed with the leaves of dimethyltryptamine-containing species of shrubs from the Psychotria genus. The brew, first described academically in the early 1950s by Harvard ethnobotanist Richard Evans Schultes, who found it employed for divinatory and healing purposes by the native peoples of the Amazonian Colombia, is known by a number of different names (see below). It has been noted that effects can be had from imbibing the Caapi vine alone, but that DMT-containing plants remain inactive when drunk as a brew without an MAO inhibitor (such as Caapi). How indigenous peoples discovered the synergistic properties of the ayahuasca brew remains unknown.

The chupacabras (Spanish pronunciation: [tʃupaˈkaβɾas], from chupar "to suck" and cabra "goat", literally "goat sucker") is a legendary cryptid rumored to inhabit parts of the Americas. It is associated more recently with sightings of an allegedly unknown animal in Puerto Rico (where these sightings were first reported), Mexico, and the United States, especially in the latter's Latin American communities. The name comes from the animal's reported habit of attacking and drinking the blood of livestock, especially goats
