Himalayan Teasel Root Classic Formulas … Natural Herb Library

Primary Actions

Tonifies the Liver and Kidney and strengthens sinews and bones - Chuan Xu Duan is classically used for low back pain, weak knees, frail tendons, and structural weakness rooted in deficiency.
Reconnects injury and supports repair - the herb is valued in traumatic injury, tendon damage, and fracture-recovery patterns where both movement and rebuilding are needed.
Secures the Chong and Ren while stopping bleeding - traditional use includes threatened miscarriage, uterine bleeding, and restless fetus when deficiency and instability underlie the presentation.

Shou Tai Wan - classic fetus-calming formula that pairs Xu Duan with Sang Ji Sheng, Tu Si Zi, and E Jiao for threatened miscarriage from deficiency.
Xu Duan Tang or Xu Duan San lineages - classical trauma and bleeding-oriented formulas that preserve the herb's reconnecting reputation.
Low-back and sinew-bone combinations with Du Zhong and Niu Xi - common traditional strategy for chronic lumbar weakness and structural instability.

Official Chinese references describe Xu Duan as bitter, sweet, acrid, and slightly warm, entering the Liver and Kidney to tonify, reconnect, and move the blood channels.
The name itself carries the idea of reconnecting what is broken, which is why the herb sits naturally at the intersection of orthopedics, gynecology, and pregnancy support.
Modern quick-reference material explicitly notes that Chuan Xu Duan is the same Dipsacus asper root as standard Xu Duan, just with regional naming emphasis.
