Bassia scoparia (also known as Kochia scoparia) has been used in traditional Chinese medicine (TCM) for a variety of ailments, including certain eye problems. In TCM, the seeds of Bassia scoparia, called "Di Fu Zi," are included in classic herbal formulas such as "Long Dan Xie Gan Tang," which is prescribed for conditions described as "damp-heat" affecting the liver and eyes. Traditional indications for Di Fu Zi include redness, swelling, and pain of the eyes, often corresponding to inflammatory or infectious conditions.

However, the evidence supporting its efficacy for eye disorders is almost entirely anecdotal and based on long-standing use within the TCM system. Modern pharmacological studies have focused more on Bassia scoparia’s anti-inflammatory, diuretic, and antioxidant properties, but these studies are limited and rarely directly investigate its effects on eye diseases or specific ophthalmic conditions. There are no high-quality clinical trials or robust scientific evidence confirming its benefit for eye health in humans.

In summary, the use of Bassia scoparia for eye problems is rooted in traditional medicine rather than modern scientific validation, and the strength of evidence supporting its use for this purpose remains weak.
