In 1941, [[Richard Evans Schultes]] first identified ololiuhqui as ''Turbina corymbosa'' and the chemical composition was first described in 1960 in a paper by [[Albert Hofmann]].<ref>{{cite journal|last1=Hofmann|first1=A|last2=Tscherter|first2=H|title=Isolation of lysergic acid alkaloids from the Mexican drug ololiuqui (Rivea corymbosa (L.)

{{quote|My chemical investigations of ''Ololiuhqui'' seeds led to the unexpected discovery that the entheogenic principles of ''Ololiuhqui'' are alkaloids, especially lysergic acid amide, which exhibits a very close relationship to lysergic acid diethylamide (<nowiki>=</nowiki>ʟsᴅ). It follows therefrom that ʟsᴅ, which hitherto had been considered to be a synthetic product of the laboratory, actually belongs to the group of sacred Mexican drugs.|author=Albert Hofmann, Burg i.L., Switzerland, November 1992<ref>{{Cite book |last=Ott |first=Jonathan |title=Pharmacotheon: Entheogenic Drugs, Their Plant Sources and History |publisher=Natural Products Co. |isbn=9780961423490 |edition=2nd Edition, Densified |publication-date=1996 |pages=13 |chapter=Foreword |orig-date=1993-07}}</ref>}}
