Rating (out of 5): 2

Barbary matrimony vine, also known as Lycium barbarum or goji berry, has a long history of use in traditional Chinese medicine (TCM), particularly to support eye health. In TCM, the berries are believed to nourish the liver and kidney, which are considered closely linked to eye function. Classical texts such as the "Shennong Bencao Jing" and later TCM materia medica reference goji berries as a remedy for improving vision, treating blurred eyesight, and alleviating eye fatigue. The traditional rationale is largely based on the doctrine of signatures and empirical observation rather than controlled scientific studies.

Modern research provides limited but emerging support for these traditional uses. Lycium barbarum is rich in carotenoids, especially zeaxanthin, which is known to accumulate in the retina and may help filter harmful blue light and reduce oxidative stress on eye tissues. Some small-scale clinical studies and animal research suggest potential benefits for protecting retinal cells and improving visual function, but these studies are preliminary and not yet conclusive. There is insufficient high-quality clinical evidence to fully validate the traditional claims. Therefore, while its use for eye health is primarily justified by tradition, there is a plausible scientific basis that warrants further investigation.
