- Latin
- Carapax Eretmochelydis
Known in TCM as Dai Mao (玳瑁), this sweet and salty, cold herb enters the Liver and Heart. Traditionally, it historically calmed the Liver and arrested convulsion ... Dai Mao was classically used for high-fever agitation, spasms, and heat-driven tremor or delirium, most often applied for fever, insomnia, and abscess. Modern research has identified Keratinous among its active constituents.

Traditional Use
Primary Actions
- Historically calmed the Liver and arrested convulsion ... Dai Mao was classically used for high-fever agitation, spasms, and heat-driven tremor or delirium.
- Historically cleared heat and resolved toxin ... older indication lists include pox-like eruptions, sores, carbuncles, and other toxic-heat lesions.
- Historically settled agitation and opened the orifices ... traditional discussion links the shell to intense heat disturbing the Heart and consciousness.
Secondary Actions
- This record is historical and documentary only ... Dai Mao comes from the hawksbill sea turtle and should not be read as a use-promoting modern materia medica page.
- It must remain separate from `turtle-shell` ... Dai Mao is hawksbill shell scute material, while Bie Jia is softshell turtle shell with a very different TCM lane.
Classic Formulas
- Historical febrile-convulsion combinations with Ling Yang Jiao, Shui Niu Jiao, or Gou Teng ... a classic heat-wind context rather than ordinary sedation.
- Historical toxin-clearing and rash-oriented prescriptions ... documentary references for pox, sores, and severe heat agitation.
- Shell-powder and decoction traditions ... important historically, but not a viable modern sourcing model.
Classical References
- Traditional herbology describes Dai Mao as sweet, salty, and cold, entering the Liver and Heart to calm wind, stop convulsion, clear heat, and resolve toxin.
- Modern conservation law and endangered-species protection override the historical use record.
Modern Research
Active Compounds
- Keratinous scute matrix and calcium-rich shell material discussed mainly in authentication rather than therapeutic literature
- Wildlife-forensic DNA markers used to identify hawksbill tortoiseshell products
- Conservation and illegal-trade data that now dominate the modern literature
Studied Effects
- A 2022 paper on illegal marine turtle exploitation underscores why hawksbill-derived medicinals belong in a conservation-first frame rather than a clinical revival frame (PMID 36069207).
- A 2016 mitochondrial DNA profiling study of illegal tortoiseshell products highlighted the continuing enforcement need for hawksbill shell identification (PMID 27364288).
- A 2015 rookery-recovery paper from the Solomon Islands showed that hawksbill populations can rebound under protection, reinforcing why historical shell use should not be normalized (PMID 25853880).

Safety & Interactions
Contraindications
- Pregnancy
- Deficiency-cold patterns without toxic heat or convulsive agitation
- Any attempted modern sourcing or clinical use of genuine hawksbill shell
Cautions
- Hawksbill-derived medicinals are ethically unacceptable and tightly constrained by modern wildlife protection.
- Any legitimate contemporary discussion should center on conservation, illegal trade, and historical context rather than use promotion.
- Legal and sustainable substitutes should be chosen for heat, toxin, or convulsion treatment goals.
