Coptis Chinensis Herb
Coptis chinensis
Traitement des infections digestives en médecine traditionnelle chinoise
Coptis chinensis works primarily through its high berberine content, which activates AMP-activated protein kinase (AMPK), a key enzyme regulating cellular energy metabolism. This mechanism helps improve insulin sensitivity and glucose uptake. Berberine also demonstrates antimicrobial activity by disrupting bacterial cell membranes and inhibiting pathogen enzyme function. Additionally, it modulates inflammatory pathways and supports cardiovascular health through lipid metabolism effects. Evidence Level: C (preclinical and limited clinical data).
Does Coptis chinensis interact with medications?
Yes, Coptis chinensis has significant drug interactions. It should not be combined with MAOI antidepressants due to potential hypertensive crisis. The berberine content may enhance effects of diabetes medications, increasing hypoglycemia risk. It may also interact with blood thinners, cytochrome P450 substrates, and blood pressure medications. Berberine can inhibit certain liver enzymes, potentially altering drug metabolism. Always consult a healthcare provider before combining with prescription medications. Evidence Level: C.
What is the recommended dosage for Coptis chinensis?
The typical adult dosage for Coptis chinensis is 2-5 grams of dried root prepared as a decoction daily. For standardized berberine extract, 500 mg taken three times daily is commonly used. Dosage may vary based on the specific condition being treated and individual tolerance. Always follow practitioner guidance, as the intensely bitter herb can cause gastric irritation at higher doses. Evidence Level: Traditional use with Level C clinical support.
Is Coptis chinensis safe during pregnancy?
No, Coptis chinensis is contraindicated during pregnancy and breastfeeding. The berberine content can cross the placental barrier and may stimulate uterine contractions, potentially causing miscarriage or premature labor. Neonatal jaundice has been associated with berberine exposure in newborns. Women of childbearing age should use effective contraception while taking Coptis chinensis supplements. This herb is rated unsafe for pregnant women. Evidence Level: C for safety data.
What is Coptis chinensis used to treat?
Coptis chinensis is traditionally used in Chinese medicine for treating digestive infections, bacterial diarrhea, and dysentery. Its antimicrobial properties make it effective against various gastrointestinal pathogens. Modern research suggests potential benefits for type 2 diabetes management through blood glucose regulation and cardiovascular health, including cholesterol reduction. It is also used to clear heat toxicity in traditional Chinese medicine frameworks. Evidence Level: C for clinical evidence; Traditional use for digestive applications.

Résumé
Coptis chinensis (Chinese goldthread) is a traditional medicinal plant containing isoquinoline alkaloids, most notably berberine, used for its antimicrobial, anti-inflammatory, and metabolic regulatory properties [PMID:32335802, PMID:10767672].
Contexte
Coptis chinensis, also known as Huanglian in China, is a medicinal plant from the Ranunculaceae family [PMID:28533961, PMID:27774066]. Its dried rhizome is the primary part used in traditional medicine [PMID:27774066, PMID:10767672].
Usages traditionnels
It has been used for centuries in Traditional Chinese Medicine for clearing heat and detoxification [PMID:33181286, PMID:40234956]. Traditional applications include treating stomach inflammation, digestive tract ulcers, and cardiovascular-associated problems such as obesity and diabetes mellitus [PMID:33181286, PMID:27774066].
Composés actifs
The herb contains isoquinoline alkaloids, including berberine (the primary constituent), epiberberine, coptisine, palmatine, jatrorrhizine, and magnoflorine [PMID:32335802, PMID:33152460, PMID:37637408]. It also contains bioactive proteins (approximately 25 kDa and 60 kDa), such as chitinase and $\beta$-glucosidase [PMID:42134700].
Mécanisme d'action
Coptis chinensis and its alkaloids act through multiple pathways: berberine regulates glycometabolism and lipid metabolism [PMID:32335802]; coptisine regulates NF-$\kappa$B, MAPK, PI3K/Akt, and NLRP3 inflammasome pathways [PMID:31622015]; and epiberberine utilizes Akt, ERK, and p53/Bax apoptosis pathways [PMID:33152460]. Additionally, it may modulate the microbiota-gut-brain axis and the TLR4/NF-$\kappa$B pathway [PMID:41131617, PMID:41197341].
Preuves cliniques
Preuve BMetabolic Disorders (Lipid-lowering and Insulin Resistance)
Lipid-lowering and insulin-resistance improving actions have been clearly demonstrated in numerous randomized clinical trials [PMID:27671811].
Preuve CInfectious Diseases
Predominant clinical uses include bacterial diarrhea, intestinal parasite infections, and ocular trachoma infections [PMID:10767672].
Preuve DColorectal Cancer
Huang-Lian-Jie-Du Decoction (containing C. chinensis) may enhance the efficacy of Capecitabine-Oxaliplatin via Akkermansia muciniphila and CD8+ T cells [PMID:40972261].
Preuve DInflammatory Bowel Disease/Colitis
C. chinensis-derived extracellular vesicle-like nanoparticles (Cc-ELNs) alleviated colitis in mice by reducing neutrophil recruitment and inhibiting NETs [PMID:40517238].
Sécurité et effets indésirables
Epiberberine is reported to have low toxicity [PMID:33152460]. In vitro studies showed that berberine can induce gene mutations in the Ames test and micronuclei in human lymphoblastoid cells by interfering with topoisomerase II; however, these effects were negated with metabolic activation and were not observed in primary human blood lymphocytes, suggesting a lack of relevance for human risk assessment [PMID:40354871].
Grossesse et allaitement
Experiments in pregnant rats and mice indicated that Chinese Goldthread Rhizome and berberine did not induce neonatal jaundice or affect glucose-6-phosphate dehydrogenase activity [PMID:19004212].
Synthèse des preuves
Evidence ranges from high-level clinical trials for metabolic effects (Level B) to preliminary animal and in vitro studies for neuroprotective, anticancer, and anti-inflammatory effects (Level D).
