Silkvine Root Bark Whole (Periploca Sepium Bunge)

Silkvine Root Bark Whole (Periploca sepium Bunge) is the dried root bark of a climbing shrub traditionally used in Chinese medicine (TCM) for its warming, tonifying, and invigorating properties. Known in TCM as Bei Wu Jia Pi, this herb has long been valued for its ability to strengthen the tendons and bones, dispel wind-damp, and support yang energy, particularly in cases of weakness and fatigue.

In traditional practice, Silkvine Root Bark is regarded as bitter, acrid, and warm in nature, entering the Kidney and Liver channels. It is commonly prescribed to treat soreness of the lower back and knees, weakness in the limbs, and joint pain due to wind-damp or cold invasion. It is also used in certain formulas to support kidney yang, invigorate circulation, and enhance endurance and vitality.

Because of its stimulating qualities, Periploca is sometimes compared to Eleutherococcus senticosus (Siberian Ginseng), another herb used to strengthen the body’s resilience and energy reserves. However, Silkvine carries a more focused warming and bone-strengthening action within the TCM framework.

Modern phytochemical studies of Periploca sepium reveal the presence of steroidal glycosides, periplocin, and triterpenes, compounds associated with cardiotonic, anti-inflammatory, and immunomodulatory effects. These constituents reflect its traditional role in restoring vitality and supporting musculoskeletal health, though they also demand careful use.

Each batch of Silkvine Root Bark Whole (Periploca sepium Bunge) is carefully harvested and dried to preserve its woody texture, aroma, and potency. When decocted, it yields a warm, slightly bitter infusion traditionally used to tonify yang, strengthen tendons, and dispel wind-damp cold.
