In 2004 and 2005 we worked on the book "Haoa Usi Mitsana, pequeño libro de medicina yagan". To this end, we held interviews with our Yagan families and with experts on natural medicine on the island. At the some time we conducted research on books and drawings.

We made numerous field trips with Julia González, Cristina Calderón and Jimena Saiter to identify and gather the natural materials we would be using (plants, fruits, algae, etc.).

We were able to make our own experiences with these remedies, their use, and their effects on different ailments.
