Coin Press - Brazilian ritual root gets second life as potential anti-depressant

At street stalls where medicinal herbs are sold, customers can buy the plant's root which contains dimethyltryptamine (DMT), a hallucinogenic substance that researchers say could be used to alleviate symptoms.

Following instructions he found on the internet, Guaracy Carvajal extracted DMT at home in 2016 from roots he bought on the street.

The 31-year-old software programmer, who had tried various treatment for chronic depression he has suffered since adolescence, said the drug makes it "feel like you've solved something in your life."

Physicist Draulio Araujo, who has conducted extensive research on the drug, said "the response is rapid. One day after treatment, (patients) already showed a significant improvement in their depression symptoms."

Yet he also warned that it "is not a magic cure" and that psychedelics "are not for everyone."

As a researcher at the Brain Institute of the Federal University of Rio Grande do Norte, Araujo and his team treated 14 people with the drug for six months.

The patients inhaled vaporized DMT, under medical supervision.

"It's common for our patients to say that something changed, that a key opened something," he said.

His patients also received psychological therapy, and some continued with conventional pharmaceutical drugs.

Neuroscientist Fernanda Palhano-Fontes, also of the Brain Institute, said "we have patients who improve significantly, others who don't improve at all."

Araujo's findings were published in the scientific journal Nature in April. In 2024, he published another study with promising results in the journal Psychedelic Medicine.

As for Carvajal, who stopped using jurema preta some time ago, he said the drug really allows a person to "start to have a lighter life."

It helped him get through a time when he was in "a state of questioning myself" about "work, day-to-day life," he said.

- Spiritual channels -

Brazil occupies a fairly prominent place in DMT research due to the substance's prominence in society, Araujo said.

While there is no ban on the cultivation or possession of jurema, which is also known as Mimosa tenuiflora, consumption of DMT is prohibited, except for religious and scientific use.

Jurema's roots are combined with other plants in a wine-like beverage that is consumed at rituals that include dancing and drums, part of Indigenous tradition in northeast Brazil where the plant grows.

"It's not hallucination," said Joyce Souza, a young woman attending a jurema ceremony in Planaltina, on the outskirts of Brasília.

"My spiritual channels become more accessible, I can communicate better with myself," Souza said.

Gathered in a house courtyard and dressed in white, the group of mostly novices waited for more seasoned practitioners to enter a trance and bring messages from ancient spirits.

Meanwhile, back in the lab, Araujo is hoping to expand his DMT research to a study of 100 patents.

"Let's say that in five years we'll have... a clear picture on when it will reach a real clinical setting," he said.
