Medicinal plants have been used for millennia across the world to heal all kinds of diseases. Today medical sciences have made great progress due to these plants. Fortunately, they have not replaced traditional medicine, which is still being practiced for the benefit of a great number of people.

In the state of Zacatecas, in Mexico, Sanjuana López and other women from the community of San Jerónimo expand their knowledge on herbal medicine thanks to a project financed by IFAD. The project keeps these traditions alive and provides scientific information.

Roots travelled with the Independent Office of Evaluation to Zacatecas to speak with Sanjuana and other participants of the "Living Pharmacy" workshop.
