Jacquinia macrocarpa pungens

In Alamos, people used to make soap from sanjuanico fruit.

Throughout the region, people made necklaces from sanjuanico flowers, a practice followed by the Mayo, the Seri and the Yaqui. The flowers were collected and dried. When rehydrated even flowers 100 years old looked as if they were fresh picked.

The last of the Mayo weavers still use sanjuanico to make a yellow dye.
