Kadsura Vine Stem Pieces (Kadsura longipedunculata) are the dried stem segments of a rare woody vine traditionally used in Chinese medicine (TCM) for its warming, blood-invigorating, and pain-relieving properties. Known in TCM as Hai Feng Teng, this herb has been treasured for centuries as a circulation-promoting and joint-supporting remedy, especially for cold-induced pain, stiffness, and restricted movement. In traditional practice, Kadsura Vine Stem is classified as acrid, bitter, and warm, entering the Liver channel. It is used to dispel wind-damp, unblock the meridians, and relieve pain, making it a key ingredient in formulas addressing arthritis, rheumatism, and muscle soreness caused by cold or damp stagnation. It is also said to nourish sinews and invigorate blood, restoring flexibility and vitality to the limbs. In folk herbal medicine, it is sometimes prepared as a warming wine infusion or decoction to ease back pain, joint stiffness, and menstrual cramping. Modern phytochemical studies of Kadsura longipedunculata have identified lignans, triterpenes, and volatile oils, which contribute to its anti-inflammatory, analgesic, and circulatory-enhancing effects. These compounds help explain its traditional use for joint mobility, musculoskeletal comfort, and microcirculation support. Each batch of Kadsura Vine Stem Pieces (Kadsura longipedunculata) is carefully harvested and air-dried to preserve its woody structure, warm aroma, and therapeutic potency. When decocted, the stems yield a mildly spicy, warming infusion that supports joint health, flexibility, and recovery from cold-damp obstruction.
