|Unknown||Salvia divinorum may have a long history of use in divination and healing ceremonies in Central America, but how far back its history goes is unknown. [Details]|
|1938||Jean B. Johnson reports learning of a Mazatec tea made from the beaten leaves of a "hierba Maria", and used for divination. 1|
|1945||Blas Pablo Reko reports a "magic plant" called “hoja de adivinación” (leaf of prophecy), used by Cuicatecs and Mazatecs to produce visions. It was probably S. divinorum. 1|
|1952||Roberto Weitlaner reports a "yerba de María" in Oaxaca. It is said to be used by curanderos (shamans or healers). 2|
|1957||Mexican botanist A. Gómez Pompa collects specimens of a hallucinogenic Salvia plant he describes as "xka [sic] Pastora". His specimens cannot be identified at the species level. 3|
|1960||R. Gordon Wasson collects samples of S. divinorum, but they are inadequate for botanical identification. 4 [Details]|
|Jul 12, 1961||Wasson ingests S. divinorum, and experiences effects. 4|
|Jun 1962||Sterling Bunnel brings the first live S. divinorum plants to the United States from Huautla de Jiménez. Cuttings from this sample are widely-propagated and are commonly available to this day. 5 [Details]|
|Oct 9, 1962||Wasson and Anita Hofmann, wife of Albert Hofmann, ingest juice of S. divinorum in a ceremony conducted by curandera Consuelo Garcia. Two days later Albert Hofmann also tried the leaves. 6|
|Dec 1962||Wasson and Hofmann collect flowering samples for identification. Carl Epling and colleagues identify it as a novel species and give it the name "Salvia divinorum". 7|
|1963||Wasson tentatively proposes S. divinorum as a candidate for the unidentified Aztec plant sacrament "pipiltzintzinli". If correct, this widely-contested hypothesis would imply a long history of cultivation and use. 8|
|1963||Dr. Shulgin begins evaluating the oral use of Salvia Divinorum leaves. At doses ranging from 5-15 mg little to no effects were felt. Just over a year later in 1964 he would try what he referred to as "Salvose" and described as a "glassy extract". Once again no effects were perceived. Salvia Divinorum does not appear in the lab books again after this. 9 [More Info]|
|1975||Ott and Diaz contemporaneously observe persons smoking dried S. divinorum leaves in Mexico City. There is no known report of S. divinorum being smoked prior to this time, and it appears to be a novel use of the plant. 10|
|1982||Ortega et al. publish a paper describing their isolation of a novel compound from S. divinorum, which they call salvinorin. 11|
|1984||Valdes et al. identify two S. divinorum derivatives which they call divinorin A and B. Divinorin A is found to be identical to the Ortega's salvinorin, so the compounds are re-named salvinorin A and B. 12|
|1994||Siebert sponsors investigation into several possible mechanisms of action for salvinorin A, but finds no evidence that it interacts with any of a few dozen common neurotransmitters and peptides. Several possibilities are eliminated, but its mechanisms of action remain unknown. 13|
|Late 1990s||Salvia becomes available commercially online and its public visibility dramatically increases.|
|Dec 11-13, 1998||1st Annual Ska Pastora, Leaves of the Shepherdess: Salvia Divinorum and Salvinorin-A [Details]|
|Dec 9-12, 1999||2nd Annual Ska Pastora, Leaves of the Shepherdess: Salvia Divinorum and Salvinorin-A [Details]|
|2002||Roth et al. report that salvinorin A is a highly-selective kappa-opioid agonist, solving the long mystery of its site of action. 14 [Details]|
|Aug 2005||Louisiana becomes the first state in the US to ban human consumption of S. divinorum. Several other states follow suit. [More Info]|
