Luisa de Álvarez de Toledo

1915-1990

An under recognized pioneer of psychedelic therapy in 1950s Argentina

Luisa Agusta Rebeca Gambier de Alvarez de Toledo (1915-1990) was an influential Argentine doctor and psychoanalyst who played a key role in the development of psychoanalysis in Argentina and Uruguay. Known as ‘Rebe’ to her friends, she was an early member of the Argentine Psychoanalytic Association (APA) and served in various leadership positions within the organization from the 1950s through the early 1970s.

Alvarez de Toledo made significant contributions to psychoanalytic theory and technique. Her 1954 paper "The Analysis of ‘Associating,’ ‘Interpreting,' and ‘Words’" [published in Spanish as “El Análisis del ‘Asociar’, del ‘Interpretar’ y de ‘Las Palabras’”] explored the central role of language in psychoanalysis and had a lasting impact on the field. In the late 1950s and early 1960s, she pioneered the use of both ayahuasca and LSD in psychedelic therapy. Working with a group of Argentine colleagues based in Buenos Aires, Alvarez de Toledo developed an innovative approach that combined psychedelics with talk therapy and group sessions in a comfortable, non-clinical environment.

Though this research was cut short due to changes in drug laws in the 1960s, it stands as an important early example of psychedelic-assisted psychotherapy.

The action of LSD 25 leads the patient to a state of prenatal regression, in which they have oceanic experiences of identity with the analyst (with the mother), with the cosmos, feeling at the peak of omnipotence; beyond time and space...

These omnipotent experiences express the opposite; the absolute dependence of the fetus in relation to the mother; an uncontrollable world that creates and sustains it.
