TCM Properties

Traditional Use

Resolves toxicity and disperses nodules — the principal TCM herb for lymph node enlargement (scrofula), thyroid nodules, carbuncles, hard abscesses, and cancer-type Phlegm-toxin masses; the anti-nodule, mass-dispersing action is its primary classical indication
Clears Heat toxicity and reduces swelling — hot abscesses, carbuncles, snake bite, insect sting, and infected wounds; topical fresh pseudobulb paste applied directly to toxin lesions
Reduces Phlegm-toxin masses — hard, fixed nodules classified as Phlegm-Stasis accumulation in TCM; combined with other Phlegm-softening and Blood-activating herbs in cancer and chronic nodule formulas

External antidote — fresh Shan Ci Gu pseudobulb ground to paste applied topically for snake bite (Pi She Shang), wasp stings, and furuncles; one of the classical emergency external applications
Clears Liver Fire — Liver Fire with red eyes, headache, and irritability in the context of Phlegm-Fire accumulation

Xiao Jin Dan (小金丹) — classical formula for scrofula, lymph node tuberculosis, and Phlegm-Stasis masses; Shan Ci Gu combined with Bai Jie Zi, Ma Qian Zi, She Xiang, Ru Xiang, and Mo Yao; dissolves Phlegm-Blood Stasis nodules; one of the main formulas still used for benign and malignant lymph node masses in TCM oncology
Zi Jin Ding (紫金锭) / Wan Ying Dan — classical multi-use detoxifying tablet containing Shan Ci Gu as a key 'five tiger' anti-toxin ingredient; combined with Shan Zha, Wu Bei Zi, Zhu Sha, and She Xiang; treats food poisoning, internal toxin, and topical infections

Ben Cao Hui Yan (Ni Zhumo, 1624 CE): 'Shan Ci Gu (山慈菇) resolves toxins, disperses nodules, treats scrofula and snake bite; the corm (pseudobulb) is the medicinal part — applied externally as a poultice or taken internally; reduces hard Phlegm masses that do not soften with ordinary treatment'
Ben Cao Gang Mu (Li Shizhen): 'Shan Ci Gu — sweet, slightly cold; enters the Liver and Spleen; treats scrofula and carbuncles, reduces masses, resolves toxins; used both internally in decoction and externally as paste; the name (mountain water-chestnut) reflects the rounded corm appearance'
COLCHICINE NOTE: Cremastra appendiculata (the primary Shan Ci Gu source) contains colchicine and related colchicine-type alkaloids; colchicine is a potent microtubule-disrupting anti-mitotic compound — the molecular basis of the anti-proliferative/anti-tumour TCM indication; it is also the active compound in modern gout treatment (pharmaceutical colchicine). However, colchicine has a narrow therapeutic index: toxicity (myopathy, bone marrow suppression, multi-organ failure) can occur with drug interactions via CYP3A4/P-gp inhibitors. Standard TCM decoction doses of Shan Ci Gu contain far less colchicine than pharmaceutical doses, but the interaction risk warrants flag=1 and documentation. The alternative source Pleione bulbocodioides contains dactylorhin lectins rather than colchicine — has lower interaction risk.

Colchicine and colchicine-type alkaloids (Cremastra fraction) — microtubule polymerisation inhibitor; anti-mitotic, anti-inflammatory (gout mechanism), cytotoxic at high doses
Dactylorhin E and military orchid glycosides (Pleione fraction) — mannose-binding orchid lectins; immunostimulatory, antiviral
β-Sitosterol and stigmasterol (phytosterols) — anti-inflammatory
Polysaccharide complex (glucomannans and fructans) — immunostimulatory, anti-tumor in vivo
Cremastrine (phenanthridine alkaloid) — anti-tumor in vitro

Anti-tumor and anti-proliferative: colchicine from Cremastra appendiculata inhibits cell proliferation across multiple cancer cell lines (breast, liver, lung, colorectal) via tubulin polymerisation disruption and mitotic arrest; validates the classical anti-cancer mass-dispersing indication; colchicine-derived drugs (vinblastine-type compounds) are modern antineoplastic agents, establishing the pharmacological rationale for the anti-tumour TCM action class
Anti-inflammatory: colchicine (pure pharmaceutical compound) is the validated treatment for acute gout — potently reduces NLRP3 inflammasome activation and neutrophil migration; Shan Ci Gu decoction extracts show similar but attenuated anti-inflammatory activity consistent with colchicine content
Antiviral: polysaccharide fractions from Pleione pseudobulbs demonstrate in vitro inhibitory activity against influenza virus and other RNA viruses; validates broad anti-toxin/anti-pathogen classical indications

Pregnancy — absolutely contraindicated; colchicine is teratogenic (disrupts spindle formation in dividing cells) and associated with miscarriage and fetal abnormalities at supratherapeutic doses
Spleen-Stomach Deficiency Cold without Phlegm-toxin masses — cool, dispersing action injures digestive Yang in Cold deficiency patterns
Known colchicine hypersensitivity

Standard dose: 3–9 g dried pseudobulb in decoction; 30–60 g fresh herb ground to poultice for external use; do not exceed standard doses
Colchicine content: standard decoction doses contain far less colchicine than pharmaceutical anti-gout doses; myopathy and bone marrow suppression risks are low at therapeutic TCM doses — but the risk multiplies dramatically with CYP3A4/P-gp inhibitors (see drug interactions)
Distinguish Cremastra vs Pleione source: Cremastra appendiculata contains colchicine; Pleione bulbocodioides lacks colchicine but has orchid lectins — pharmacologically distinct; market supplies often mix the two; Pleione source carries lower interaction risk

CYP3A4 inhibitors (clarithromycin, erythromycin, azithromycin, verapamil, diltiazem, itraconazole, ketoconazole) — SERIOUS: CYP3A4 is the primary metabolic pathway for colchicine; concurrent CYP3A4 inhibitors dramatically increase colchicine plasma levels to potentially toxic concentrations; macrolide antibiotic + colchicine is a known clinically fatal drug combination at pharmaceutical doses; monitor carefully even at TCM decoction doses
P-glycoprotein inhibitors (cyclosporine, quinidine, verapamil) — P-gp is the primary efflux pump for colchicine; P-gp inhibitors increase colchicine bioavailability and toxicity risk; cyclosporine combination is particularly dangerous
Statins (HMG-CoA reductase inhibitors — simvastatin, atorvastatin) — colchicine + statins increases myopathy risk; monitor for muscle pain and weakness
