Project MKULTRA/Subproject 1

Subproject 1 was a U.S. Central Intelligence Agency program, active in 1953 and operating under the aegis of Project MKULTRA, organised for the purpose of researching and financing the study of Rivea Corymbosa (also known as ipomoea corymbosa, turbina corymbosa), a species of morning glory, the seeds of which contain ergine (LSA), an ergoline alkaloid similar to LSD. Available documentation reveals the agency paid an unidentified researcher in the Princeton University chemistry department to isolate and characterise "the alkaloids of Ipomoea Sidafolia Choisy (Rivea Corymbosa) in order to determine their activities as agents affecting the central nervous system of human beings." The later Subproject 22 continued research in this area.
