1, job's tears and grass beads are two different things. It's easy to tell when shelling, but it's hard to tell the truth when shelling. We should distinguish the true from the false by their characters, colors and tastes.

2. Caozhu is also called Hui Hui Rice, Coix lachryma, Chuangu, Caobodhi or Bodhi. They are the seeds of wild Coix lachryma-jobi, and their shells are hard and shiny, just like painting. Because grass beads have natural pores and luster in the middle of the shell, people often use them to string door curtains, beads or bracelets.

3. Common edible coix seed and grass bead belong to the same species. They are all coix lachryma-jobi plants, but they are two different varieties. Although coix seed and grass bead have similar efficacy, the medicinal efficacy of grass bead is far lower than that of coix seed, which is also the main reason for trying to distinguish them.

4. It is easy to distinguish between coix seed and grass bead, because grass bead is bigger than coix seed, and its shell is hard and smooth, and it has its own luster. Coix seed is smaller than grass bead, and its shell is brittle and dull.

5. Coix lachryma-jobi has a smooth surface, occasionally yellowish brown seed coat, one end is blunt and round, the other end is wide and slightly concave, the hilum is light brown and punctate, and the cross section is white and powdery. The surface of grass beads is not smooth, and occasionally there are residual reddish-brown seed coats. Umbilical cord with flat ends and brown and black spots at one end. The cross section is white or translucent keratin-like.

6. The really good coix seed color is milky white and slightly cyan, while the color of grass beads is milky white and slightly transparent. The white one is smoked with sulfur. Neither coix seed nor grass beads are suitable for eating or medicine, which is completely out of consideration.

7. Really good coix seed, which tastes slightly sweet after being cooked, has a sticky taste and is a little sticky in the mouth. If there is no such taste and taste, it is a fake such as grass beads. In addition, Job's tears and grass beads will not be bitter, nor will they taste of traditional Chinese medicine. If they taste spicy, bitter or traditional Chinese medicine, it means that they have been stored for too long and are old.

8. The starch content of grass beads is not as good as that of coix seed, but the content of protein is higher than that of coix seed. Both of them are edible, but the edible value and medicinal value of grass beads are not great. If Chinese medicine shops use grass beads as medicine, it is shoddy.
