Goji berry, known as Gou Qi Zi in Traditional Chinese Medicine, has been valued for centuries as a tonic for the liver, kidneys, and eyes. Modern research suggests that its rich profile of polysaccharides, zeaxanthin, and betaine may contribute to antioxidant activity, with studies indicating potential benefits for immune function, eye health, and blood sugar regulation. Preliminary findings also point to possible protective effects on liver cells and a role in supporting healthy aging, though much of this evidence comes from animal or small-scale human studies. Commonly consumed as dried fruit or brewed into tea, goji berries remain one of the most widely researched traditional botanicals, with ongoing investigations continuing to explore the extent and mechanisms of their potential health-supporting properties.
