Xuefengteng (Ventilago leiocarpa) is a medicinal liana commonly found in the mountain forests of southern China.

Xuefengteng is a folk umbrella term for a group of medicinal woody lianas, and the plants it refers to vary slightly from region to region; the more common account identifies it as Ventilago leiocarpa, a plant in the buckthorn family (Rhamnaceae). It is mainly distributed in the mountainous areas of southern China, where it is commonly seen in open woodlands, forest edges and valley thickets, climbing up other trees with its twining habit.

Xuefengteng is a perennial evergreen liana with slender, tough stems and branches, and old vines have rough outer bark. Its leaves are alternate and nearly leathery in texture, its flowers are tiny and inconspicuous, and its fruit often bears wing-like structures that let the seeds be dispersed by the wind. The word "blood" in its folk name is mostly related to its traditional use in treating blood deficiency, rheumatism and similar conditions.

In traditional usage, the roots and stems of Xuefengteng are the main parts used; folk practitioners often used it to dispel wind and dampness and to relax the sinews and invigorate the collaterals, and it was often mentioned alongside liana medicines such as Jixueteng (Millettia reticulata) for dealing with problems like rheumatic bone pain and blood deficiency with general weakness. It should be noted that medicinal use should be carried out under professional guidance, and it is not advisable to dig it up and take it on your own.

If you want to cultivate it artificially, Xuefengteng prefers a warm, humid climate and is fairly shade-tolerant; it is best planted in well-drained soil rich in humus, with a trellis set up for it to climb. It can be propagated by sowing or by cuttings, and in daily care it is enough to keep the soil moist and provide appropriate shade. Wild resources have been dwindling year after year due to harvesting, so when you come across it in the mountains, leaving the plant in place to protect the source is the sustainable way to use it.
