American ethnobotanist From Wikipedia, the free encyclopedia
Daniel J. Siebert was an ethnobotanist, pharmacognosist, and author who lived in Southern California.[1]
Siebert had studied Salvia divinorum for over twenty years and was the first person to unequivocally identify (by human bioassays in 1993[2]) Salvinorin A as the primary psychoactive substance of Salvia divinorum.[1][3] In 1998, Siebert appeared in the documentary Sacred Weeds shown in the United Kingdom.[1] He had 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]
