ESPD50

Ethnopharmacologic Search for Psychoactive Drugs

On the 50th anniversary during the month of June 2017 an international group of specialists finally gathered again to share their perspectives on past, present, and future research in the field of ethnopharmacology. The symposium was held at the spectacular Tyringham Hall in Britain. Synergetic Press published a collector’s box set including the first edition of 1967 plus a brand new book with the 50th anniversary symposium’s findings.

“The discovery of ESPD’s publication changed my life. For me, at least, that book was influential because it provided a cultural context for psychedelics based on traditions older and richer than anything I had encountered in mass media sources.”
