Rhizome of Heartleaf Drynaria

Traditional Use

Primary Actions

• Tonifies the Liver and Kidney and strengthens bones ... Gu Sui Bu is classically used for weak low back and knees, sore sinews, loose teeth, and chronic deficiency affecting the skeleton.
• Mends sinews and reconnects injured bone ... it is a signature herb for fractures, traumatic injury, and slow recovery after damage to bone or tendon.
• Supports Kidney-deficiency patterns that show up in the teeth and lower body ... traditional use extends to tooth looseness, tinnitus, and weakness after overwork when depletion underlies the presentation.

Secondary Actions

• This page should stay on the accepted Drynaria roosii medicinal rhizome lane rather than drifting into generic ornamental-fern discussion.
• Gu Sui Bu is regularly paired with Xu Duan, Du Zhong, or Zi Ran Tong when the treatment goal is both movement and structural repair.

Classic Formulas

• Gu Sui Bu with Xu Duan and Du Zhong ... classic bone-and-sinew support strategy for chronic weakness or post-traumatic recovery.
• Trauma formulas pairing Gu Sui Bu with Zi Ran Tong, Ru Xiang, or Mo Yao ... used when fractures, bruising, and pain all need attention together.

Classical References

• Traditional materia medica describes Gu Sui Bu as bitter and warm, entering the Liver and Kidney to reconnect injured bones and strengthen the lower back and knees.
• The herb's name literally points toward mending broken bones, which is why it remains a signature traumatology tonic rather than a generic anti-inflammatory fern.
