Celandine
Specifically for Multiple Chemical Sensitivity
0 up • 0 down
Why it works for Multiple Chemical Sensitivity:
There is no credible clinical evidence that greater celandine (Chelidonium majus) treats Multiple Chemical Sensitivity (MCS / idiopathic environmental intolerance). On the contrary, oral celandine preparations have a well-documented risk of liver injury; regulatory bodies (EMA/HMPC) have concluded the oral benefit–risk is negative except for tightly-controlled traditional preparations with very low alkaloid content.
- Traditional/herbal medicine uses: greater celandine has a long folk history for liver/gallbladder complaints, skin problems and “detox”-type indications. That folk use is why some practitioners or patients try it for MCS (patients often try liver/“detox” herbs). Frontiers MDPI
- Pharmacology: the plant contains many isoquinoline alkaloids (chelidonine, sanguinarine, berberine, etc.) that have measurable biological effects in cells and animal studies (anti-microbial, spasmolytic, cytotoxic in lab assays). Those mechanisms do not amount to clinical proof for MCS. MDPI
Summary: historical use + in-lab activity → hypothesis generation, not proof that celandine will help MCS in people.
How to use for Multiple Chemical Sensitivity:
Because there is no evidence base for MCS, there are no evidence-based clinical instructions for using celandine to treat MCS. What exists are traditional/herbal or homeopathic posologies — but those are not supported by trials and come with important safety restrictions:
- Regulatory safety limit (EU HMPC / EMA): For oral preparations the EMA documents and related assessments set an upper safety limit of about 2.5 mg total alkaloids per day; the HMPC concluded oral use has an unfavorable benefit–risk profile in many contexts and recommended caution/withdrawals in some Member States. If any practitioner still considers oral use (not recommended for MCS), the alkaloid limit is an important safety parameter. Flore European Medicines Agency (EMA)
- Common (non-evidence) preparations reported in herbal sources: tinctures, infusions, dried herb (traditional tincture ratios and folk dosages vary). These are traditional doses you may see listed in herbal manuals — they are not clinical recommendations for MCS and are accompanied by the EMA safety concerns above. (Example herbal posologies are listed in herbalist sources; again: not evidence-based for MCS.) The Naturopathic Herbalistarzneipflanzenlexikon.info
- Homeopathic Chelidonium (high dilutions / pellets) is a separate preparation form widely used by homeopaths for “liver” complaints; homeopathic uses are not supported by conventional clinical evidence for MCS. If you see “Chelidonium” on a homeopathy label it is not the same as using the whole-plant herbal tincture. Homeopathy at DrHomeo.com
Practical medical point: Because MCS is a condition where patients are often sensitive to agents, and because celandine contains biologically active alkaloids and can cause irritation/allergy, adding a plant extract is likely to cause adverse effects for some sufferers. There are no validated instructions to recommend celandine for MCS.

Regulatory assessment / public statement: EMA/HMPC assessment and public statement on Chelidonium majus (assessment report and final public statement). These explain evidence gaps and safety concerns. Must-read for safety/dosing. European Medicines Agency (EMA)
Hepatotoxicity / clinical reviews: focused clinical reviews and case series describing greater celandine-associated hepatotoxicity and acute hepatitis. These summarize case reports of liver injury and discuss causality. ScienceDirect European Review
MCS clinical context / lack of pharmacologic cures: JACI-In Practice review and other recent reviews that summarize diagnosis and management of MCS / idiopathic environmental intolerance (note lack of proven herbal cures). jaci-inpractice.org ScienceDirect
Specific Warnings for Multiple Chemical Sensitivity:
Hepatotoxicity (liver injury): Multiple case reports and reviews associate oral Chelidonium preparations with cholestatic or hepatocellular hepatitis, sometimes severe. Regulatory agencies have flagged this repeatedly. If you have liver disease or take hepatotoxic drugs, do not take oral celandine. ScienceDirect Flore
Regulatory caution / EMA position: The HMPC/EMA concluded that the benefit–risk of oral use is negative in many contexts and recommended restrictions; an upper limit of ~2.5 mg total alkaloids/day is mentioned for preparations where a traditional use monograph is retained. This is a safety ceiling — not a treatment endorsement for MCS. European Medicines Agency (EMA) Flore
Topical effects — skin irritation and allergic contact dermatitis: The fresh latex is caustic; topical use can cause blistering, burns or allergic contact dermatitis. Use caution with topical applications. SynapseBotanical-online
Pregnancy / breastfeeding and children: Generally advised avoid or use only under specialist supervision. Many sources list pregnancy and lactation as contraindications (safety not established). The Naturopathic Herbalist Happy Herb Co
Drug interactions / special populations: Because of liver metabolism concerns and unknown interactions, avoid with other hepatotoxic drugs or when hepatic function is impaired. ScienceDirect
People with MCS may be more sensitive: MCS patients commonly report sensitivity to plant extracts, perfumes, tincture alcohols, etc.—introducing a herb may provoke symptoms rather than help them. No controlled evidence supports benefit and real risk exists for harm (especially liver). jaci-inpractice.org BMJ Open
General Information (All Ailments)
What It Is
Celandine is a herbal plant, scientifically known as Chelidonium majus, belonging to the poppy family (Papaveraceae). Commonly referred to as Greater Celandine, it is a perennial herb native to Europe and western Asia, but now found in many temperate regions worldwide.
The plant has distinctive yellow flowers, deeply lobed leaves, and a bright orange latex-like sap that oozes when the stem is broken. This sap has long been used in traditional medicine, particularly for treating warts, liver ailments, and digestive issues.
Its key bioactive compounds include alkaloids such as chelidonine, sanguinarine, berberine, and chelerythrine — all of which contribute to its physiological effects. Celandine is commonly available in forms such as tinctures, teas, extracts, and topical salves.
How It Works
Celandine’s medicinal properties stem from its complex alkaloid composition, which interacts with several biological systems:
- Digestive Support – Certain alkaloids (especially chelidonine and berberine) promote bile secretion from the liver and gallbladder, improving digestion and helping relieve conditions like biliary dyskinesia, indigestion, and gallstones.
- Antispasmodic Effect – It helps to relax smooth muscles in the digestive tract, reducing cramps and intestinal spasms. This is one reason why Celandine was historically used for stomach and intestinal discomfort.
- Antimicrobial & Antiviral Properties – Compounds like sanguinarine and chelerythrine exhibit strong antibacterial and antifungal activity, explaining the plant’s topical use for skin infections and warts.
- Liver Protection (Hepatoprotective) – In controlled amounts, Celandine may aid liver function and protect against certain toxins, though excessive use can have the opposite effect (hepatotoxicity).
- Analgesic & Anti-inflammatory Effects – The alkaloids may also reduce pain and inflammation by modulating the activity of neurotransmitters and inflammatory mediators.
Why It’s Important
Celandine holds significance for several reasons — cultural, medicinal, and pharmacological:
- Traditional Medicine – It has been used since ancient Greek and Roman times for treating jaundice, liver problems, and skin growths. In folk medicine, it was viewed as a “cleansing” herb for the body’s detoxification systems.
- Modern Herbalism – Today, it remains a key component in herbal formulas aimed at liver health, detoxification, and gastrointestinal comfort.
- Scientific Research – Celandine’s alkaloids are of ongoing interest in pharmacology for their potential anticancer, antiviral, and antimicrobial effects.
- Holistic Importance – Its role in supporting liver function connects it to the broader goal of maintaining systemic balance, energy metabolism, and overall vitality in holistic medicine.
In short, Celandine bridges ancient herbal wisdom with modern biomedical exploration, offering both historical value and ongoing scientific curiosity.
Considerations
While Celandine can provide notable health benefits, caution is essential due to its potent bioactive compounds:
- Toxicity Risk – Overuse or improperly prepared extracts can cause liver toxicity, nausea, or digestive irritation. The line between a therapeutic and toxic dose is relatively narrow.
- Medical Supervision – It should be used only under the guidance of a qualified herbalist or healthcare professional, especially for individuals with liver disease, gallstones, or bile duct obstruction.
- Pregnancy & Breastfeeding – Not recommended, as its alkaloids may be harmful to fetal development or pass through breast milk.
- Topical Use – The orange sap can irritate the skin if applied excessively; caution is advised when using it directly on warts or lesions.
- Drug Interactions – Celandine may interact with prescription medications, particularly those metabolized by the liver (e.g., certain painkillers, antidepressants, or antiviral drugs).
In essence, while Celandine can be a valuable herbal ally, it should be respected for its potency and pharmacological power — ideally used in moderate doses and with professional oversight.
