Squawvine (Mitchella repens) is an herb traditionally used by Native American tribes and in early American herbal medicine, primarily for issues related to women's reproductive health. Its use for supporting the bladder or urinary tract, however, is less prominent but still noted in some herbal traditions. Historical records indicate that squawvine was sometimes used as a mild diuretic and to support urinary tract function, but such uses are secondary to its primary application as a parturient (to aid childbirth) and for menstrual discomfort.

There is very limited scientific research on squawvine in general, and essentially no modern studies evaluating its effectiveness or mechanism for supporting bladder health or treating bladder conditions. The evidence for its use in this context is therefore based almost entirely on traditional herbal practices and anecdotal reports, rather than clinical trials or pharmacological research. Consequently, its rating for evidence supporting bladder health is low.

In summary, squawvine’s use for supporting the bladder body system is justified by tradition, but not substantiated by scientific evidence. Anyone considering its use should consult with a qualified healthcare provider, particularly given the lack of rigorous safety or efficacy data.
