We are currently witnessing a renaissance in the field of psychiatry in the use of psychedelic substances as a treatment for various psychiatric conditions that prove resistant to the medications offered by the pharmaceutical industry.
The ancestral wisdom of indigenous peoples
Indigenous peoples deserve deep recognition for the ancestral knowledge they have preserved for centuries about the spiritual, therapeutic, and communal properties of these psychedelic substances of plant, fungal, and animal origin. Cultures from Siberia, the Amazon, Mesoamerica, Africa, and other regions of the world already used sacred plants and fungi in shamanic rituals, healing ceremonies, and processes of social cohesion. We have testimonies of these rituals dating back to prehistoric times. This knowledge was not the result of casual experimentation, but of deep observation of nature and intergenerational transmission based on respect, experience, and the spiritual dimension of life.
Substances such as psilocybin from the so-called “sacred mushrooms,” ayahuasca, peyote cactus, and many others have been part of ritual practices oriented toward emotional healing, connection with community, and the search for existential meaning. For a long time, these traditions were disparaged or persecuted through a colonial lens and by Western cultural models that regarded these practices as primitive or superstitious. However, contemporary medicine and psychiatry are today rediscovering the therapeutic potential of these substances.
Science catches up
In recent decades, numerous scientific studies have shown that psychedelics such as psilocybin or LSD can help in cases of treatment-resistant depression, anxiety associated with serious illness, post-traumatic stress, or addictions, especially when conventional treatments have not been effective. Prestigious research centers and hospitals in Europe and North America have begun integrating these substances into rigorous therapeutic protocols, thereby recovering, albeit from a scientific perspective, part of the knowledge that indigenous peoples had already developed long before.
It is important to remember that during the 1950s and 1960s, LSD and psilocybin were legal substances, widely studied in medical and psychological settings. However, amid a context of social and cultural change, these substances were broadly prohibited, often more for political and ideological reasons than scientific ones. This prohibition interrupted promising research for decades and contributed to stigmatizing both psychedelics and the traditional cultures that used them.
Toward regulation and recognition
Today, some countries and regions are reviewing these policies and moving toward the regulation or decriminalization of certain traditional psychedelics, especially when used for therapeutic or spiritual purposes. This shift also represents an opportunity to recognize the value of indigenous knowledge and to affirm respect for the peoples who have kept this wisdom alive despite persecution and misunderstanding.
Recognizing indigenous peoples does not simply mean accepting that “they already knew,” but understanding that their relationship with nature, health, and consciousness can offer a complementary and necessary perspective for the contemporary world. The current recovery of psychedelics in medicine should be accompanied by an exercise in historical humility, cultural respect, and justice toward those communities that, for centuries, have safeguarded this knowledge for the benefit of individuals and community alike.
