Male huayruro seeds can be used in ceremony. The name huayruro comes from the seed of the huayruro plant (Ormosia sp) that grows in the Amazon rainforest. This seed is characterized by being part red and part black, visually suggesting complementary and duality. Perhaps due to this unusual natural characteristic there has been the belief among Peruvians that these seeds have the dual power to attract good fortune and ward off evil spirits. Sold in packages of 12 seeds.
