Quick Summary
Greater Celandine (Chelidonium majus) is a medicinal plant containing isoquinoline alkaloids and phenolic compounds. It has been studied primarily for its topical antimicrobial properties and potential role in wound healing. Clinical evidence to support its efficacy for functional gastrointestinal disorders or systemic diseases is limited, with most observed benefits reported in preclinical or in vitro studies. Safety concerns mainly involve potential hepatotoxicity and phototoxicity, with limited data on human safety. More rigorous clinical trials are needed to clarify its efficacy and safety in humans.
What is it
Greater Celandine is a perennial herb native to Europe and parts of Asia, known for its bright yellow-orange sap and small yellow flowers. The plant has a long history of use in traditional medicine, often applied externally or consumed in various herbal formulations. It contains diverse bioactive constituents, particularly alkaloids and phenolic compounds.
Traditional Uses
- Topical treatment for skin conditions and wounds
- Management of digestive complaints such as dyspepsia and irritable bowel syndrome
- Support for respiratory ailments and infections in traditional systems
Active Compounds
Key active compounds in Greater Celandine include:
- Isoquinoline alkaloids (e.g., chelidonine, sanguinarine)
- Phenolic compounds
- Furanocoumarins (associated with phototoxicity)
Potential Benefits with Evidence Levels
- Antimicrobial activity (topical use, wound healing)
Evidence level: Preclinical and in vitro studies
Several studies demonstrate strong antimicrobial effects of Chelidonium majus extracts against Gram-positive bacteria in vitro. When combined with sericin, these properties may support topical wound healing applications with low cytotoxicity. The plant’s pharmacological compounds may reduce inflammation and promote tissue regeneration relevant to wound care.

Evidence level: Limited clinical evidence and review conclusions
Current clinical data do not strongly support Chelidonium majus for managing IBS or related functional gastrointestinal disorders. Studies on herbal medicines for IBS generally show inconclusive results, and Chelidonium majus-specific evidence is lacking.

Use of Evidence-Based Herbal Medicines for Patients with Functional Gastrointestinal Disorders (2020) - Potential antiviral, antibacterial, and anti-inflammatory effects
Evidence level: Experimental and traditional use with some supportive in vitro data
Experimental studies show that alkaloids from Chelidonium majus may have antibacterial, antifungal, antiviral, and anti-inflammatory properties. For example, formulations for vaginal delivery demonstrated these effects alongside in vitro safety.

Side Effects
- Potential hepatotoxicity (liver injury) reported in association with herbal products containing Chelidonium majus alkaloids
- Skin phototoxic reactions due to furanocoumarins and related compounds
- Local irritation or allergic reactions with topical applications (rare, limited data)
Drug Interactions
Specific drug interactions involving Greater Celandine are not well documented. However, due to the presence of bioactive alkaloids, theoretical interactions with drugs metabolized by liver enzymes cannot be excluded. Clinical data are insufficient, and more research is needed to clarify herb-drug interaction risks.
Who Should Avoid It
- Individuals with pre-existing liver disease or impaired hepatic function should avoid use due to hepatotoxicity risk
- Those with known photosensitivity or risk of phototoxic skin reactions
- Pregnant and breastfeeding women, as safety data are insufficient and potential toxicity is a concern
Evidence Limitations
- Lack of high-quality, large-scale randomized controlled trials evaluating clinical efficacy and safety in humans
- Most data are preclinical, in vitro, or based on traditional use and small clinical studies with methodological limitations
- Variability in herbal preparation composition complicates interpretation and reproducibility
- Limited pharmacokinetic and herb-drug interaction information available
- Adverse event reports mainly come from spontaneous case reports lacking systematic safety monitoring
