Sargent's Vine (Red Vine)

Sargentodoxa cuneata

In Chinese herbalism, the tough, woody stem of this forest vine is known as Da Xue Teng, or big blood vine, and has long been gathered from the mountain woodlands where it climbs old trees toward the light. Herbalists traditionally simmered the sliced stem into decoctions meant to invigorate the blood and clear stagnation, reaching for it when pain settled into the joints, the abdomen, or the monthly cycle. It has also traditionally been used to support recovery after minor injury, in keeping with the old idea that a plant which bleeds red sap can help blood move freely again. Village healers in the herb's native range considered it a reliable, everyday remedy rather than an exotic one, the kind of vine every household recognized by sight.

Safety.

Sargentodoxa is not significantly toxic, but because it strongly invigorates the blood, it is traditionally avoided during pregnancy and used cautiously with blood-thinning medications, where it may raise bleeding risk.
