What types of ritual use Ayahuasca?

Ayahuasca[note 1] is a South American[1] psychoactive and entheogenic brewed drink traditionally used both socially and as a ceremonial or shamanic spiritual medicine among the indigenous peoples of the Amazon basin, and more recently in North America and Europe.[2][3][4] The tea causes altered states of consciousness often known as "psychedelic experiences" which include visual hallucinations and altered perceptions of reality.
