What is Sang Ji Sheng and what makes it unique?

Sang Ji Sheng (Mulberry Mistletoe, Taxillus chinensis) is unique among wind-damp dispelling herbs because it ALSO tonifies the Liver and Kidney and nourishes Blood. Most wind-damp herbs only dispel pathogenic factors, which can further weaken deficiency patients. Sang Ji Sheng dispels wind-damp (for joint pain) while simultaneously strengthening the Liver-Kidney (the root of bone and tendon health). This dual action makes it ideal for chronic rheumatic and arthritic conditions where the patient has both wind-damp obstruction AND underlying organ deficiency — a very common presentation in elderly patients.

Can Sang Ji Sheng be used during pregnancy?

Yes — Sang Ji Sheng is one of the few wind-damp dispelling herbs that is considered safe during pregnancy when prescribed by a qualified TCM practitioner. It is traditionally used to calm the fetus and prevent miscarriage in women with Kidney deficiency who also have lower back pain. Its ability to tonify the Kidney (which 'holds' the fetus) while relieving back pain makes it particularly useful during pregnancy. However, as with all herbs during pregnancy, it should only be used under professional supervision.

Sang Ji Sheng (桑寄生): Mulberry Mistletoe in TCM — Dispelling Wind-Damp While Nourishing Liver and Kidney

What Is Sang Ji Sheng?

Sang Ji Sheng (桑寄生), the dried stems and leaves of Mulberry Mistletoe (Taxillus chinensis), is one of the most valuable herbs in the TCM pharmacopeia for treating chronic joint and lower back pain. What makes it unique is its dual nature: it simultaneously dispels wind-dampness (treats the symptoms) AND tonifies the Liver and Kidney (treats the root).

This dual action addresses a common clinical reality: most chronic joint pain patients have both excess (wind-damp obstruction) and deficiency (Liver-Kidney weakness). Sang Ji Sheng treats both in a single herb.

Why the Host Tree Matters

Sang Ji Sheng is a parasitic plant. TCM considers the host tree significant:

Mulberry tree (桑) host = best quality (Sang = mulberry)
The mulberry is valued in TCM — its leaves, twigs, and fruit all have medicinal use
The parasite absorbs and transforms the host’s properties
This is why “Sang” (mulberry) is specified in the name
