Job’s tears, also known as adlay or adlay millet, is a tall grain-bearing perennial tropical plant of the family Poaceae (grass family). In its native environment it is grown at higher elevation areas where rice and corn do not grow well. Job’s tears are also commonly sold as Chinese pearl barley.
There are two main varieties of the species, one wild and one cultivated. The wild variety, has hard-shelled pseudocarps—very hard, pearly white, oval structures used as beads for making prayer beads or rosaries, necklaces, and other objects. The cultivated variety is harvested as a cereal crop, has a soft shell, and used medicinally in parts of Asia.
