Zanthoxylum Riedelianum

Zanthoxylum riedelianum is a species of flowering plant in the Rutaceae family, commonly known as Riedel's prickly ash or the Brazilian pepper tree. Native to Brazil, this plant is primarily found in the Atlantic Forest biome. It typically grows up to 10 meters tall and features a dense, rounded crown with thorny branches. The leaves are compound, consisting of 5 to 9 leaflets that are glossy green on top and paler underneath. The small, greenish-yellow flowers bloom in clusters from October to December. The fruit of Zanthoxylum riedelianum is a small berry that changes from green to red when ripe. It has a pungent aroma and spicy taste due to its high essential oil content, including compounds such as limonene, citral, eugenol, and linalool. Traditionally, indigenous communities have used this plant for its medicinal properties, particularly for its analgesic effects against ailments like toothaches and rheumatism. Ecologically, Zanthoxylum riedelianum plays an essential role by providing food for birds such as thrushes and tanagers. These birds feed on its fruits and help disperse its seeds throughout the forest. Although considered an invasive species outside Brazil due to its rapid growth and ability to outcompete native vegetation, it remains an important cultural symbol within Brazilian folklore. During New Year celebrations known as "Festa de São João," it is believed that hanging branches of this plant around homes can ward off evil spirits.
