Pangolin Scales — Safety & Interactions
Chuan Shan Jia · Squama Manitis
Use with caution. Practitioner review recommended before use.
Contraindications
- Pregnancy — absolutely contraindicated; strong Blood-activating action causes uterine contractions and significant risk of miscarriage; one of the strongest classical pregnancy contraindications in TCM
- Open abscesses with pus already draining — the 'promoting suppuration' action is only appropriate for unruptured abscesses; inappropriate if rupture has already occurred
- Qi and Blood Deficiency without Stasis — powerful Blood-moving drug requires adequate Qi to drive; exhausts Qi in severely deficient patients
- LEGAL: possession and use of genuine Chuan Shan Jia is illegal in China (2020 ChP removal) and internationally (CITES Appendix I); practitioners must use validated substitutes
Cautions
- Historical dose: 3–10 g roasted scales in decoction; 1–1.5 g powder (chong fu); the drug was always processed (roasted in sand or vinegar-treated) before internal use
- ETHICAL AND LEGAL ADVISORY: Chuan Shan Jia should not be used in clinical practice; any product claiming to contain genuine pangolin scales is either illegal or fraudulent; validated TCM substitutes exist for all classical indications
- Adulteration: given the species ban, commercially available 'Chuan Shan Jia' is frequently adulterated with pig skin, fish scales, or synthetic polymer scales; practitioners should be aware that authentic pangolin-derived products cannot be legally sourced
