Celandine (Chelidonium majus)

Celandine (Chelidonium majus) is a European medicinal plant containing alkaloids like chelidonine and sanguinarine that demonstrate anticancer and antimicrobial properties. These compounds work by disrupting cellular processes in cancer cells while preserving healthy tissue.

Origin & History

Celandine (Chelidonium majus) is a perennial herb native to Europe and West Asia, now naturalized worldwide, belonging to the poppy family (Papaveraceae). The plant contains a distinctive yellow-orange latex and is harvested for its aerial parts (0.27-2.25% alkaloids) and roots (3-4% alkaloids), with extraction typically using methanol, ethyl acetate, or water to isolate bioactive compounds.

Historical & Cultural Context

Chelidonium majus has been used for centuries in European and East Asian traditional medicine systems for antimicrobial, anticancer, and anti-inflammatory purposes. Historical applications included treating skin conditions, infections, and digestive issues, utilizing the plant's distinctive latex and alkaloid content.

Health Benefits

• Anticancer potential: In vitro studies showed methanol and ethyl acetate extracts demonstrated strong cytotoxic activity against gastric (HGC-27) and colon (HT-29) cancer cells without harming non-cancerous cells (PMID: 38301936) - evidence quality: preliminary
• Antimicrobial activity: CM-AMP1 peptide from aerial tissue exhibited membrane-lytic antibacterial effects against E. coli through bacterial stress response mechanisms (PMC10959680) - evidence quality: preliminary
• Antioxidant properties: High phenolic and alkaloid content in methanol extracts demonstrated cholinesterase and tyrosinase inhibition - evidence quality: preliminary
• Traditional anti-inflammatory support: Historical use suggests anti-inflammatory benefits, though no clinical studies available - evidence quality: traditional only
• Digestive health support: Traditional applications include digestive issues, though lacking modern clinical validation - evidence quality: traditional only

How It Works

Celandine's primary bioactive alkaloids, including chelidonine, sanguinarine, and chelerythrine, exert cytotoxic effects by inducing apoptosis in cancer cells through mitochondrial dysfunction and DNA fragmentation. The antimicrobial peptide CM-AMP1 disrupts bacterial cell membranes, while other alkaloids inhibit topoisomerase enzymes. These compounds selectively target abnormal cells while demonstrating minimal toxicity to healthy tissue.

Scientific Research

No human clinical trials, RCTs, or meta-analyses were identified in the available research. Evidence is limited to in vitro studies, including one examining cytotoxic effects on cancer cell lines (PMID: 38301936) and another investigating the antimicrobial peptide CM-AMP1's effects on E. coli (PMC10959680).

Clinical Summary

Current evidence for celandine is limited to preliminary in vitro studies. Laboratory research showed methanol and ethyl acetate extracts demonstrated strong cytotoxic activity against gastric (HGC-27) and colon (HT-29) cancer cell lines without harming non-cancerous cells. Antimicrobial studies identified the peptide CM-AMP1 with activity against various pathogens. No human clinical trials have been conducted to establish safety or efficacy, making the evidence quality preliminary and insufficient for therapeutic recommendations.

Nutritional Profile

Celandine (Chelidonium majus) is a medicinal herb rather than a dietary staple, so macronutrient content is not well-characterized in nutritional databases; however, as a leafy plant it contains approximately 15-25% dry weight protein, ~5-10% lipids, and ~40-50% carbohydrates including cellulose and pectins. The primary bioactive compounds are isoquinoline alkaloids, present predominantly in the latex and aerial tissues: chelidonine (0.1-1.0% dry weight, the most abundant), berberine (0.01-0.1%), coptisine (0.05-0.3%), sanguinarine (0.01-0.05%), chelerythrine (0.01-0.1%), and stylopine. Chelidonic acid (pyran-2,6-dicarboxylic acid) is a characteristic non-alkaloid constituent at approximately 0.2-0.5% dry weight. Flavonoids include rutin, quercetin, and kaempferol glycosides at combined concentrations of ~0.5-1.5% dry weight. Hydroxycinnamic acid derivatives (caffeic acid, chlorogenic acid, ferulic acid) are present at ~0.1-0.5%. Carotenoids (beta-carotene, lutein) contribute to the yellow-orange latex pigmentation. Vitamin C has been detected in aerial parts (~20-50 mg/100g fresh weight). Minerals include potassium (~300-500 mg/100g dry weight), calcium (~200-400 mg/100g dry weight), magnesium (~100-200 mg/100g dry weight), and iron (~5-15 mg/100g dry weight). Bioavailability note: alkaloid absorption is significant via mucous membranes and GI tract; however, sanguinarine and chelerythrine have narrow therapeutic-to-toxic margins. The plant is NOT used as a food source due to hepatotoxicity risk; all concentrations are for reference in medicinal/research contexts only.

Preparation & Dosage

No clinically studied dosage ranges have been established in human trials. In vitro studies used various extracts without specifying doses equivalent to human intake. Consult a healthcare provider before starting any new supplement.

Safety & Interactions

Celandine contains hepatotoxic alkaloids that can cause serious liver damage, particularly with prolonged use or high doses. The plant's latex is highly irritating to skin and mucous membranes and can cause severe contact dermatitis. Celandine may interact with medications metabolized by cytochrome P450 enzymes and should be avoided during pregnancy and breastfeeding due to potential teratogenic effects. Internal use is banned or restricted in several countries due to liver toxicity concerns.
