Area of Science:

Ethnobotany
Biodiversity Informatics
Conservation Science

Background:

Traditional knowledge (TK) on medicinal plants is vulnerable to cultural change and environmental degradation.
Ethnobotanical databases are crucial for conserving TK and advancing scientific research.
Brazil possesses rich medicinal flora and cultural diversity, necessitating robust documentation efforts.

Purpose of the Study:

To present Ewé, a novel online database for Brazil's medicinal flora.
To facilitate the documentation and conservation of traditional plant uses.
To provide tools for hypothesis generation and meta-analyses in ethnobotanical studies.

Main Methods:

Development of an online database using open-source tools.
Inclusion of data on medicinal flora, specifically testing with the Leguminosae family.
Compilation of use reports from literature and herbarium sources.

Main Results:

The Ewé database is now available online at www.ewedb.com.
Test data includes 2078 use reports for the Leguminosae family.
Ewé incorporates visualization tools for large datasets, distinguishing it from existing databases.

Conclusions:

Ewé serves as a valuable resource for the conservation of traditional knowledge on Brazilian medicinal plants.
The database enhances the potential for hypothesis generation and meta-analyses in ethnobotany.
Accessible online tools like Ewé are vital for safeguarding cultural and biological heritage.
