Daniel J. Siebert is an ethnobotanist, pharmacognosist, and author who lives in Malibu, California.[1]
Siebert has studied Salvia divinorum for over twenty years and claims to be the first person to unequivocally identify (by consuming it in 1993[2]) Salvinorin A as the primary psychoactive principal of Salvia divinorum.[1][3] In 1998, Siebert appeared in the documentary Sacred Weeds shown in the United Kingdom.[1] He has discussed Salvia divinorum on National Public Radio,[4] Fox News, CNN,[5] Telemundo and his comments have appeared in the Los Angeles Times, USA Today, and The New York Times.[1]
In 2002, Siebert wrote a letter to the United States Congress in which he objected to bill H.R. 5607 introduced by Rep. Joe Baca (D-California) which sought to place Salvia divinorum in Schedule I of the Controlled Substances Act.[6]
In 2010, like the twelve years preceding it, he stated plans on publishing a book about Salvia divinorum called Divine Sage. [7]
