Known in TCM as Gui Ban (龟板), this salty and sweet, cool herb enters the Heart, Kidney, and Liver. Traditionally, it nourishes Yin and anchors rising Yang ... raw Gui Ban is used for chronic deficiency patterns with tidal heat, dizziness, bone steaming, and restless depletion, most often applied for low back pain, dizziness, and night sweats. Modern research has identified Collagen among its active constituents.

Traditional Use

Primary Actions

  • Nourishes Yin and anchors rising Yang ... raw Gui Ban is used for chronic deficiency patterns with tidal heat, dizziness, bone steaming, and restless depletion.
  • Strengthens bone and fills marrow ... classical use extends to weak low back and knees, developmental weakness, and long-standing structural depletion.
  • Supports blood and stabilizes deep deficiency patterns ... tortoise plastron is also used when Chong and Ren weakness, deficiency heat, and constitutional exhaustion appear together.

Secondary Actions

  • This page should stay distinct from `prepared-tortoise-plastron` ... the raw plastron record preserves the colder, more specimen-forward Gui Ban lane rather than the pharmacy-prepared version.
  • It also must remain separate from `tortoise-shell` and from the softshell-turtle `Bie Jia` family ... shell-derived Yin medicinals are related, but they are not interchangeable.

Classic Formulas

  • Da Bu Yin Wan ... the classic Kidney-Yin and deficiency-heat formula where Gui Ban helps cool bone steaming while supporting deep depletion.
  • Da Ding Feng Zhu ... tortoise plastron enriches Yin and extinguishes internal wind in severe chronic deficiency patterns.
  • Zuo Gui Wan and related essence-tonifying strategies ... Gui Ban or its gelatin derivatives are selected when marrow and structural support are central.

Classical References

  • Materia medica tradition describes Gui Ban as nourishing Yin, suppressing Yang, strengthening bone, and benefiting chronic deficiency states.
  • Its heavy descending nature explains why it appears in long-cook formulas for deep deficiency rather than in quick symptomatic treatment.

Modern Research

Active Compounds

  • Collagen peptides and gelatin-like protein fractions ... major constituents discussed in plastron extract studies
  • Mineral-rich bone matrix fractions ... relevant to the classic bone-strengthening lane
  • Amino acids and small bioactive extract constituents ... explored in osteogenic and neurodifferentiation research

Studied Effects

  • A 2021 study found that Plastrum testudinis extract suppressed osteoclast differentiation through NF-κB pathway effects and improved senile osteoporosis outcomes in preclinical work (PMID 33974944).
  • A 2019 study reported that Plastrum Testudinis extracts promoted proliferation and osteogenic differentiation of rat bone-marrow mesenchymal stem cells, closely matching the traditional bone-strengthening lane of Gui Ban (PMID 30984279).
  • A 2020 study found that Plastrum Testudinis extracts promoted neural stem-cell differentiation into dopaminergic neurons, showing that modern research interest extends beyond skeletal use alone (PMID 32382312).

Safety & Interactions

Contraindications

  • Spleen or Stomach deficiency with poor digestion of heavy rich substances
  • Exterior excess or damp accumulation without clear Yin deficiency

Cautions

  • Raw Gui Ban is heavy, rich, and slow-acting ... it is not a casual short-term supplement.
  • Animal-source identification matters because tortoise plastron, broader tortoise-shell material, and softshell turtle shell occupy different clinical lanes.
