Hamburger Beans

Seeds from the Mucuna vine are called Hamburger Beans or True Sea-Beans in the United States. In Mexico, they are known as Ojo de Venado or Deer’s Eye. There are hundreds of varieties growing in tropical regions around the globe.They can be brown, red or brindle shades of red and brown. These beans are members of the pea and bean family that contain toxic, hallucinogenic or medicinal alkaloids and therefore figure in good luck charms. In the case of the Mucuna bean, the mature beans are considered both aphrodisiac and very protective in Mexico and Central America against the evil eye. Nowadays they are carried for good luck.
