Kaxinawá legend states that one day many people in tribe became very ill and their Pajé (Medicine Man) had done everything possible to cure them. Under the effect of sacred plant medicines, he entered the forest and received a visit from ‘The Grandmother’. She brought in her hands a frog, from what she took a white secretion and taught the Pajé how to apply it. Returning to the tribe following the guidelines he had received, the Pajé cured his tribe. From then on, he was known as Pajé Kampu.
After his death it is said that his spirit lives on in the frog where it protects the health of those who defend the forest. The secretion became known as Kambo through some tribes will call it Sapo. Kampu or Vacina De Floresta.
