Traditional UsesWhile specific traditional medicinal uses for Calystegia binghamiae are not widely documented or recommended due to its rarity and potential toxicity, other species within the Convolvulaceae family, including some Calystegia, have historically been used as strong purgatives, primarily from the root. Some traditional applications might have included mild diuretic effects or external use for skin conditions, though these are not well-substantiated for this specific species and carry risks.
