Her testimony became the seed of what would later become the Nagoya Protocol on Access and Benefit-Sharing (2014). But more immediately, it sparked the Matsés Traditional Medicine Project (1994–2001), the first-ever indigenous-led effort to document and protect traditional knowledge before outsiders could claim it. Saika trained 12 young Matsés—both men and women, breaking the shamanic gender taboo—to interview elders, press plant specimens, and translate their uses into three languages. The resulting 800-page manuscript, Nuestro Monte, Nuestra Vida , was never commercially published. It exists as a digital lockbox: outsiders may read summaries, but the full text requires a Matsés elder’s permission.
Today, in the Matsés territory, a new kambo ceremony is never opened without an elder reciting her words: “The frog gives its poison. The vine gives its dream. But only the people give the permission.” And in laboratories far away, where researchers isolate compounds for new antibiotics or antidepressants, they now include a line in their ethics statements: “Knowledge sourced with prior informed consent.”
Saika Kawateka died in 2019, not of old age, but of complications from a wasp sting—a humbling reminder that the forest she loved never promised safety, only relationship. Her funeral was attended by botanists from Kew Gardens, lawyers from the World Intellectual Property Organization, and the children of the same rubber tappers who had once hunted her people. They came because Saika had taught them a singular lesson: that a plant’s name is not a fact to be extracted, but a story to be shared. saika kawatika
She had no concept of “alkaloids” or “receptor antagonists.” But she had a system: the Matsés pharmacopoeia, an oral encyclopedia of over 300 medicinal plants, each coded by taste, texture, animal behavior, and spiritual warning. Saika was its youngest living archivist.
But Saika was different. She was curious, not fearful. At fifteen, she saved the life of a lost Brazilian botanist, Pedro Esteves, who had stumbled into their territory riddled with fever. While her father chanted icaro songs over him, Saika prepared a brew of crushed chiric sanango roots—a neuromuscular blocker used in hunting. Esteves, delirious, scribbled notes on bark. When he recovered, he asked her one question: “How do you know which plants heal and which kill?” Her testimony became the seed of what would
By 1985, logging companies had begun circling the Matsés reserve. Their scouts carried satellite maps, but Saika carried something more powerful: a chacruna leaf in her mouth and a plan. She realized that the outside world valued her knowledge only as a commodity. When a pharmaceutical representative offered her village $5,000 for rights to study the kambo frog secretion (a potent immune stimulant), Saika refused. Her father had taught her that the frog’s poison was not a product—it was an ancestor who had agreed to help the Matsés in exchange for ritual respect.
In the humid, electric air of the upper Amazon Basin, where the canopy blurs the line between green and gold, a quiet revolution began not with a machete’s flash, but with a whisper. That whisper was Saika Kawateka, a woman of the reclusive Matsés people, whose name would one day be etched into scientific journals and international treaties—though she herself never learned to read them.

Born in a palm-thatched maloca around 1958, Saika was the youngest of a shaman’s three daughters. Her people called themselves the “jaguar’s kin,” and they had avoided permanent contact with the outside world until a brutal encounter with rubber tappers in the 1960s. By the time Saika was ten, half her village had perished from influenza brought by missionaries. The rest fled deeper into the labyrinth of rivers, becoming masters of invisibility.
