Daniel Siebert

Daniel J. Siebert is an ethnobotanist, pharmacognosist, and author who lives in Malibu, California.

Siebert has studied Salvia divinorum for over twenty years and claims to be the first person to unequivocally identify (by consuming it in 1993) Salvinorin A as the primary psychoactive principal of Salvia divinorum. In 1998, Siebert appeared in the documentary Sacred Weeds shown in the United Kingdom. He has discussed Salvia divinorum on National Public Radio, Fox News, CNN, Telemundo and his comments have appeared in the Los Angeles Times, USA Today, and The New York Times.

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.

In 2010, like the twelve years preceding it, he stated plans on publishing a book about Salvia divinorum called Divine Sage.
