It has been shown to aid in cancer prevention, alleviate muscle tension, and reduce joint inflammation, as well as regulate blood pressure, blood sugar, and cholesterol levels. It also helps prevent gout and supports skin whitening and anti-aging.Additionally, coix seed contains a variety of bioactive compounds, including polysaccharides, flavonoids, terpenes, sterols, and alkaloids.

This is believed to help expel blood from the lungs and gradually heal the condition. Simple methods like this have been used since ancient times to treat lung cancer and continue to offer valuable insights for modern practices.Research has shown that polysaccharide extracts from coix seed can induce apoptosis (programmed cell death) in nonsmall cell lung cancer (NSCLC) cells, thereby aiding in the inhibition and treatment of NSCLC, the most common form of lung cancer.In addition to lung cancer, coix seed may also be beneficial in treating malignant tumors of the female reproductive system, such as breast cancer and cervical cancer. Studies have shown that coix seed and its extracts can inhibit the proliferation, invasion, and migration of various cancers, including colon, liver, gastric, and pancreatic cancers, while promoting cancer cell apoptosis. It may also serve as a significant adjunctive therapy in cancer treatment.Relief for Joint InflammationAnother notable benefit of coix seed is its ability to relax muscles and relieve cramps.
