Historically, Sinicuichi is actually an ancient divination plant, affectionately called "The Sun Opener", reportedly allowing practitioners, while in a trance state, to recall events which took place many years earlier as if they had happened yesterday. The drink that has been made from this plant is called Sinicuichi as well, and is referred to as the "magical drink causing oblivion" by the Mexicans.

The author of Magical Poisons, published in 1938, reports a curious pattern of commonality in experiences reported by the Sinicuichi drinkers he worked with. Those he studied would often “lose clear and correct orientation concerning space and time” after consuming the drink. But, he goes on to say that while partakers were under the spell of Sinicuichi, that “ideas and memories from years ago, which have engraved themselves into their memories, are correctly reproduced. Some babble that they are able to precisely recall occurrences that took place within the first few days of their lives, and others report that they can recall events that took place before they even came into the world, things that their grandfathers may have experienced.”

It is important to note that every one of these studies made a drink out of the FRESH leaves of Sinicuichi plant, and not the dried ones which are available commercially by venders such as us. The traditional preparation of the Sinicuichi drink involves leaving slightly wilted leaves in water for a day, and then pressing these thoroughly the following day. The juice obtained in this was then allowed to ferment.
