The tea has had many names including Santo Daime (or simply Daime), Hoasca, Ayahuasca, Yage, and Caapi. It is made from two or more plants, one a woody vine (Ayahuasca vine or Jagube; generally "Banisteriopsis caapi"), and the others known as admixtures. While various plants are used throughout South America, most of which have high concentrations of dimethyltryptamine, the preferred admixture in the case of Santo Daime is "Psychotria viridis", known to church members as the "Queen of the Forest," after the figure who is said to have appeared to the church's founder in a vision, prompting him to start the religion. DMT occurs naturally in the human body and is speculated to be released at the time of death, but it is normally digested in the stomach if consumed and an MAOI (monoamine oxidase inhibitor), in this case tetrahydroharmine, harmine and harmaline, is needed to allow it to reach the brain in this way, thus the use of the vine. The Santo Daime Church uses only the Jagube vine and the Viridis leaf, not adding any other plants to the mixture. The tea is prepared ceremoniously over a week by members of the church in a festival called a 'feitio'. Hymns are sung, and Daime is drunk while the men hammer the vine into powder and the women clean and sort the leaves. Because of the very specific manner in which they prepare their sacrament, and the very specific way in which they use it, the beverage is not called 'Ayahuasca', but 'Santo Daime'. In some communities there are very clear distinctions.
