Stellaria dichotoma, also known as "Yin Chai Hu" in traditional Chinese medicine (TCM), has been used historically in Chinese herbal formulations. Its primary traditional indications include clearing deficiency heat, treating night sweats, and alleviating fever due to yin deficiency. There are scattered references in traditional texts and herbal compendia that suggest it may have an effect on urinary frequency or nocturnal urination (bedwetting), often as part of multi-herb formulas aimed at supporting kidney and bladder function in children. However, these uses are based on TCM theory rather than modern biomedical understanding, and Stellaria dichotoma is not a principal herb for enuresis in most respected TCM sources.

Scientific research on Stellaria dichotoma for the treatment of bedwetting (nocturnal enuresis) is extremely limited. No significant clinical trials or pharmacological studies have directly supported its efficacy for this condition. Most available evidence is anecdotal or based on traditional use rather than rigorous scientific validation. Therefore, the evidence rating remains low (1/5), reflecting weak support from traditional sources and a lack of scientific evidence.
