Silkvine Root Bark Powder (Periploca Sepium Bunge)

Silkvine Root Bark Powder (Periploca sepium Bunge) is the finely milled form of the root bark of the silkvine plant, a traditional herb known in Chinese medicine (TCM) as Bei Wu Jia Pi. Revered for its warming, strengthening, and restorative effects, it has been used for centuries to invigorate yang energy, fortify the tendons and bones, and dispel wind-damp cold.

In traditional practice, Silkvine Root Bark is classified as bitter, acrid, and warm, entering the Liver and Kidney channels. It is commonly prescribed for weakness of the lower back and knees, soreness of the joints, cold pain in the limbs, and general fatigue associated with yang deficiency. It also appears in classical formulas intended to support circulation, increase physical endurance, and relieve stiffness or swelling caused by damp-cold conditions.

As a powdered form, it allows for easy blending into herbal capsules, tinctures, liniments, or tonifying formulas, offering convenience while maintaining the herb’s traditional potency.

Modern research on Periploca sepium identifies cardiac glycosides, triterpenes, and flavonoids among its active constituents, associated with circulatory stimulation, anti-inflammatory effects, and immune regulation. These bioactive compounds correspond to its historical reputation as a yang tonic and musculoskeletal strengthener, though they also warrant careful dosing and professional supervision due to their intensity.

Each batch of Silkvine Root Bark Powder (Periploca sepium Bunge) is carefully prepared from premium-grade root bark and ground to a fine consistency to preserve its warm, slightly bitter flavor and bioactive integrity. The powder can be used in decoctions, capsules, or external preparations for its warming, strengthening, and damp-dispelling properties.
