Vegetative characteristics

The celandine is a deciduous, biennial to perennial herbaceous plant that reaches heights of up to 70 centimeters. It forms a branched rhizome . Their milky juice is yellow-orange.

The alternate leaves are divided into a petiole and a leaf blade. The green-gray leaf blade, which is frosted by a thin wax film, is notched. The underside of the leaf is lighter and slightly hairy ( trichomes ).

Generative characteristics

The flowering period extends from May to October. The hermaphrodite flowers are four-fold and about two centimeters in size. The two sepals fall off early. Its four petals are yellow. There are twelve to many free stamens . Two carpels have become an ovary grown. The stylus ends in a two-lobed scar. The thin, bilobed capsule fruit is about five centimeters long and contains few to many seeds. The egg-shaped, black seeds carry a cock-comb-shaped caruncula .

The number of chromosomes in Europe is 2n = 12, in Japan, in Chelidonium majus subsp. asiaticum H.Hara 2n = 10 or 12.

ecology

Greater celandine is a hygromorphic hemicryptophyte .

When the hairy stems break off or the leaves tear, a yellow-orange milky sap emerges from articulated milk tubes . The poisonous juice has a sharp, bitter and very unpleasant taste.

In cool, rainy weather, the flowers are closed and the flower stalks lower. The pollination is effected by insects ( Entomophilie ). There is also self-pollination .

The seeds are spread by ants ( myrmecochory ), which are attracted by the caruncula.

Occurrence

Originally, celandine was widespread in the temperate and warm-tempered areas of Eurasia and the Mediterranean . It was taken to North America by settlers who used it as a remedy for skin diseases and is therefore considered a neophyte there .

This nitrogen-loving species grows widespread in the vicinity of human dwellings, for example on rubble sites, at roadsides, in black locust trees and even in crevices, but also in the mountains .

The celandine occurs in Central Europe in societies of the order Glechometalia but also of the association Arction. In the Allgäu Alps, it rises in the Tyrolean part in the plain near Steeg up to 1250 m above sea level.

The ecological indicator values ​​according to Ellenberg for Chelidonium majus are: L6 = penumbra to half-light plant, T6 = moderately warm to warm indicator, Kx = indifferent behavior, F5 = indicator of freshness, Rx = indifferent behavior, N8 = pronounced nitrogen indicator, S0 = does not bear salt.

Common names

Ingredients and their effects

Description of the ingredients

The celandine contains a number of alkaloids, over 20 of which have been isolated and chemically identified. The most important are berberine , chelerythrine , chelidonine , coptisine , sparteine , chelidoxanthin and sanguinarine . The alkaloids are present both in the above-ground parts of the plant and in the root. In autumn they concentrate in the root, which then becomes highly toxic.

(-) - Scoulerin is the biogenetic precursor of the main alkaloids
Sliced ​​stem with leaked milky juice

The alkaloids are predominantly of the benzophenanthridine , protoberberine or protopine type , depending on their chemical structure , and are derived biogenetically from (-) - scoulerin , a benzyl isoquinoline . Among them, coptisin is the main alkaloid. Chelerythrine is the most potent. Some alkaloid salts are yellow or orange in color and give the milky sap its characteristic color. Furthermore, celandine contains proteolytic enzymes in the milk sap. Other ingredients of the plant are organic acids such as malic , citric and chelidonic acids, as well as caffeic acid esters and flavonoids .

Alkaloid analysis

The identification of the alkaloids is possible by thin layer chromatography or high performance liquid chromatography .

A thin-layer chromatographic analysis of the celandine alkaloids serves - in addition to the macroscopic and microscopic examination of the dried herb - the identification of celandine ( Chelidonii herba ) according to the European Pharmacopoeia . For this purpose, a test solution prepared according to the instructions is chromatographed on silica gel in addition to a reference solution containing methyl red and papaverine . The zone sequence obtained from the test solution is assessed in comparison with that from the reference solution after spraying with Dragendorff reagent and sodium nitrite solution .

Pharmaceutical qualities of celandine must contain at least 0.6 percent total alkaloids, calculated as chelidonin. The predominant chelidonium alkaloids in terms of quantity contain dioxymethylene groups, from which formaldehyde can be split off with strong acids (the pharmacopoeia method prescribes sulfuric acid) , which reacts with chromotropic acid to form a purple-red dye . This is measured quantitatively spectrophotometrically at 570 nm. Using the “specific absorption” for chelidonin, the amount is converted (“calculated as chelidonin”).

The celandine root ( Chelidonii radix ) is not monographed in the European Pharmacopoeia.

In vitro and in vivo effects

Celandine extracts have an in vitro antiviral , antibacterial , antifungal , anti-inflammatory and mildly toxic ( cytotoxic ) effect on human cells, which is attributed to the content of chelidonin, coptisin and protopin . Chelerythrine and sanguinarine are also cytotoxic. A weak effect against influenza viruses was found in vivo .

The following effects of isolated alkaloids are mentioned: antispasmodic ( spasmolytic ) on the smooth muscles and central sedative (chelidonine and protopine), choletic (berberine), weakly analgesic (chelidonine), central paralyzing and irritating to the mucous membrane (chelerythrine), AChE- inhibiting ( sanguine- inhibiting).

Fresh celandine is sometimes highly poisonous for animals. However, cases of poisoning are rare because of the unpleasant taste of the plant.

Effects in medical application

In folk medicine , the juice of the plant is used externally for skin diseases such as warts , either native or as an ointment ("Glaucionsalbe", Latin also "Glaucina" ). Protein-dissolving ( proteolytic ) and antiviral mechanisms are discussed as the principle of action . The juice and the ointment can be very irritating. However, if the juice is applied to a wart for several days, it can go away completely. The color begins to fade after a short time and repeated hand washing. However, the benefits are insufficiently documented in clinical studies.

Because of the papaverine-like, slightly spasmolytic and cholagogic effects of the alkaloids typical of chelidonium, preparations made from the herb drug are or were used internally for spasmodic complaints in the gastrointestinal tract and in the biliary tract.

Oral pharmacokinetic studies show that high concentrations of chelidonium alkaloids occur in the stool and only low concentrations in the liver. An accumulation in the liver was not observed. The excretion via the kidneys is low. The findings indicate that poor absorption, but not a high first-pass effect, is mainly responsible for the low systemic bioavailability . In particular, the resorption of the quaternary alkaloids (chelerythrine, sanguinarine) is estimated to be very low.

Medical efficacy for dosages with an intake of 2.5 milligrams of celandine total alkaloids or less has not been adequately proven.

unwanted effects

After the dermal application of Chelidonium majus for the treatment of warts, the occurrence of contact dermatitis has been observed, which decreased after discontinuation of therapy.

Swallowing parts of the plant in large quantities leads to severe irritation of the gastrointestinal tract . Accordingly, the symptoms manifest themselves in burning, pain, increased salivation, vomiting , bloody diarrhea , weakness in arms and legs, dizziness and circulatory disorders such as accelerated breathing and increased pulse rate. In severe cases of poisoning, death from circulatory failure can occur.

Celandine is suspected of causing dose-dependent toxic liver damage ( hepatitis , cholestasis and even liver failure ) after internal use of therapeutic doses . Since 1993, new reports of suspected liver damage from preparations containing celandine have been made known.

A change in the assessment of the benefit-risk ratio can be seen in the documents that were created for companies and authorities to simplify approval procedures. After the publication of the positive monograph of Commission E in 1985, in which celandine and its preparations - average daily dose of 2-5 g of drug or 12-30 milligrams of total alkaloids - for the treatment of spasmodic complaints in the biliary tract and gastrointestinal tract Tracts were positively assessed, followed in 2003 by the adoption of a monograph by the European Scientific Cooperative on Phytotherapy (ESCOP). She also assessed the risk-benefit ratio as positive in the indication “slight cramps in the upper gastrointestinal tract, slight biliary complaints and dyspeptic complaints such as flatulence” and refers to preparations for adults and children from 12 years of age with a mean daily dose of 1.2–3.6 grams of crushed medicinal drug as a tea infusion and various extracts, including a standardized extract with 9–24 milligrams of total alkaloids (calculated as chelidonin ).

The Committee for Herbal Medicines (HMPC) of the European Medicines Agency, on the other hand, classified the risk-benefit ratio of celandine in preparations for internal use as negative in 2011: The data situation is for a “well-established-use” indication (“general medical use “) Not sufficient for monopreparations made from celandine. Even if one considers a daily dose of less than 2.5 mg total alkaloids as harmless, the benefit remains questionable. A “traditional application” is proven, but is not advocated because of the numerous reports of potential liver damage. A European harmonized monograph could therefore not be drawn up.

In 2005, the Federal Institute for Drugs and Medical Devices initiated a step-by-step procedure based on reports of hepatotoxic reactions with the aim of reducing the maximum permissible daily dose for total alkaloids from 2.5 mg to 0.0025 mg (ie 2.5 micrograms) and the approval of drugs withdraw with a higher dose. The safety factor of 1000 for the daily dose of 2.5 mg total alkaloids, which is safe according to studies, was justified with insufficient relevance of the studies for the long-term effects in humans. The authorities did not derive the proposed limit value from the available side effect reports , but based it on in vitro data on rat hepatocytes . In April 2008, the BfArM issued the step-by-step plan notification, which, however, deviated from the original plan insofar as the approval of celandine-containing medicinal products with a higher daily intake of now 2.5 milligrams of total alkaloids (calculated as chelidonin) would be revoked if a dosage was given between 2.5 micrograms and 2.5 milligrams of total alkaloids per day, however, warnings should be included in the package insert.

Celandine components are also said to be contained in the controversial cancer drug Ukrain .

history

etymology

Celandine goes back to Middle High German schëlkrūt , also called schëlwurz . The name “Chelidonium” was first mentioned by Dioscurides and Pliny . They differentiated between a "large Chelidonium" and a "small Chelidonium". According to Dioscurides and Pliny, the name is derived from the Greek word χελιδών chelidon , German 'swallow' , and refers to the fact that the chelidonium begins to bloom when the swallows arrive and wilts when the swallows leave. In 1976, however, it was precisely assumed that the original name was probably due to the common gray-blue color of certain species of swallow and a “herba chelidonia” (cf. Middle Latin celidonia ). "But there are other ways of interpretation".

In Gart health (1485), in small Destillierbuch of Hieronymus Brunschwig (1500) and by the fathers of botany "lesser Chelidonium" as was celandine ( Ficaria needle ), the "big Chelidonium" as celandine ( Chelidonium majus interpreted). In ancient times and in the Middle Ages, chelidonia minor can also refer to turmeric or a type of horned poppy such as red horned poppy or yellow horned poppy ( Chelidonium glaucium ).

Antiquity - late antiquity

Dioscurides and Pliny reported that the swallows used the juice of the chelidonion to heal their blind young. The juice of the "large chelidonium" mixed with honey was considered a remedy for "darkening the eyes". The root, when chewed, should relieve toothache. It was taken with white wine and aniseed for the treatment of jaundice ("icterici sive auriginosi") (cf. signature theory ). Large and small chelidonium were used externally to treat skin diseases, but the “small chelidonium” was used especially as an externally applied caustic agent. These indications were adopted by later authors. The indications mentioned in Dioscorides were also mentioned outside of the technical prose.

middle Ages

Little book about the burnt-out waters . Cover photo. 15th century

The doctors of the Arab Middle Ages also quoted from the works of Dioscurides.

In the Physica attributed to Hildegard von Bingen (12th century) it was stated that celandine contains a “dark and bitter poison” that is more harmful than useful to humans. However, when mixed with old lard, the celandine juice can heal internal ulcers.

In the German Macer (13th century), another application of celandine was stated: "The roots pounded with vinegar vnde that used with wisem wine help the giggling vunde růmet di brust."

In the printed versions of the little book on the burnt waters , ascribed to the Viennese doctor Michael Puff , which appeared in rapid succession from 1477 until well into the 16th century, a new indication was given for the distilled water obtained from celandine : “It is also good drunk for die bermůter. ”In the manuscripts that appeared before the printing and which served as a template for the printed“ Little Book of Burnt Waters ”, this addition was not included. Instead it said that the mother swallow would heal the eyes of her young with the juice of the celandine. In the 15th and 16th centuries, the name bermutter referred to menstrual cramps ("The uterus rises up and creates pain in the abdomen") but also generally cramp-like pain in the abdomen in women and men, in young and old.

From the second half of the 15th century, a recommendation can also be found, according to which flowering celandine should be placed in a sevenfold distilled wine together with cumin . A small amount of the resulting tincture should be mixed with two-thirds of wine every morning. This potion should be used for disease prevention and long life in health. In addition to the golden women's hair moss and the sundew , the celandine in particular was used by some alchemists to represent the materia prima and the aurum potabile . The selection criterion was the golden-yellow color of the celandine juice. They interpreted the name “chelidonium” as “donum coeli - heavenly gave”.

16th Century

Hieronymus Bock (1498–1554)

The fathers of botany also interpreted the “smaller chelidonium” as celandine ( Ficaria verna ) and the “large chelidonium” as celandine ( Chelidonium majus ). They adopted the indications for celandine from their predecessors. Hieronymus Bock divided these indications into:

  • Internally: to open the liver in jaundice, to heal infectious diseases ("pestilentz")
  • Externally: as eye medication, against stains on the face and "pestilentzblattern", to divert serous or fibrinous exudates ("limb water") caused by joint inflammation or injuries, to treat poorly healing wounds ("fistulas" and "cancer"), toothache , Stomach grief , warts in the anal and genital region ("feigwartzen")

Sources from the 16th century (selection):

17th and 18th centuries

In 1768 Jacques-Christophe Valmont de Bomare wrote in the revision of his Dictionnaire raisonné :

"This plant, 4 to 5 onces [approx. 120 to 150 g] prepared and taken as an infusion in water or whey, has a diuretic effect [- diurétique -] and it is suitable for releasing blockages of the spleen, liver and ureter and especially for curing jaundice caused by thickening of the Lymph has arisen in the vessels. (The celandine cures jaundice by making the bile in the bile ducts fluid.) It is also said that celandine use is harmful if the jaundice is caused by liver inflammation, or by an acute illness such as convulsions or a bite Viper was caused. It is also claimed that the juice of the celandine ingested expels poison through sweat. But you can only take a moderate amount of it, because the juice is so hot that it often causes terrible symptoms. "

Further sources from the 17th and 18th centuries (selection):

19th century

Mathieu Orfila (1787-1853)

Mathieu Orfila , the founder of modern toxicology , reported in 1815 on experiments in which he administered aqueous extracts or the juice from celandine leaves internally and externally to dogs. Orfila realized that celandine and its extract, both internal and external at the dosages he used, cause violent accidents with fatal consequences. He also found that celandine and its preparations also act on the lungs. From the second third of the 19th century, the newly discovered ingredients of celandine, especially its alkaloids , were the subject of toxicological studies.

Chelidonin . In 1824 the Parisian chemist JP Godefroy noticed an alkaloid while examining the celandine, which he called "chélidonine". When Leo Meier repeated the analysis steps given by Godefroy in Königsberg in 1827, however, he did not find an alkaloid. The discovery of chelidonin was attributed to JMA Probst , who made it pure in 1839. The pharmacist Reuling in Umstadt found after a self-experiment in 1839: “Chelidonin has little or no narcotic effect. Five grains [approx. 0.3 g] sulfuric acid chelidonin ingested only produces a bitter, salty, scratchy, pungent taste ”.

Chelerythrine - Sanguinarine . In 1839, JMA Probst made the alkaloid chelerythrine from the celandine and the yellow horn poppy . In 1842 Jacob Heinrich Wilhelm Schiel (1813–1889) stated that the American chemist James Freeman Dana (1793–1827) made it from the Canadian roots in 1828 Bloodweed ( Sanguinaria canadensis ) represented sanguinarine is identical to Probst's chelerythrine. In 1869 Ludwig Weyland tried sanguinarine (chelerythrine) in animal experiments on the frog. According to Husemann (1871 and 1883), 0.06 g of the alkaloid known as chelerythrine and sanguinarine caused vomiting in humans, and 0.001 g subcutaneously killed frogs and 0.02 g rabbits. Symptoms of poisoning resulted in adynamia and clonic or even tonic convulsions . Death resulted from paralysis of the respiratory center . Small doses increased the pulse rate and blood pressure, while large doses reduced it by paralyzing the vasomotor center and the heart.

Chelidonic acid . While investigating the herb and the roots of the celandine, JMA Probst discovered chelidonic acid in 1839. Lerch (1846), Hutstein (1851) and Wilde (1863) subsequently published the results of their research on this vegetable acid.

In 1831, the Berlin doctor Emil Osann specified the following forms and dosages for the medical use of celandine:

1. usually as an extract from the herb (Chelidonii herba) dissolved in water or in pill form.
According to the third edition of the official Prussian Pharmacopoeia from 1804, celandine extract was obtained only with water as an extractant. From the fourth edition onwards, the instructions for preparing the celandine extract have been changed so that alcohol is added after the juice mixed with water has been squeezed out. This made the extract water-alcoholic. In the German Pharmacopoeia published in 1872 , a regulation for the production of an aqueous-alcoholic celandine extract was given.
The recommended dosages were given very differently. For the aqueous extract, Pfaff (1821) recommended a dosage of five to ten grains (approx. 0.3 to 0.6 g) and Link / Osann (1831) a dosage of half a drachm to a whole drachm (approx. 8 to 3.6 g).
The extract was used internally for "congestion in the liver and portal vein system" with hardening of the liver, gallstones, hemorrhoidal complaints ..., for "dropsy due to congestion and weakness of the organs of the abdomen", for "three- and four-day alternating fever" and for skin rashes (" scrofulous and venereal dyscrasias ")
2. Less often the freshly squeezed juice from the herb and / or from the root.
According to Link / Osann (1831), the dose was a scruple (approx. 1.2 g) to one drachma (approx. 3.6 g) two to three times a day together with other herbal remedies ( dandelion , earth smoke , couch grass ) as a spring cure for "blood purification"
The freshly squeezed celandine juice was also used on warts and genital warts.
The fresh herb was used as a poultice for the treatment of "flaccid ulcers" and for the resorption of foot edema.

A tinctura chelidonii made from celandine was a major liver product of the Rademacher school and was given in 5–20 drops 3–4 times a day.

20th to 21st century

Celandine is suspected of causing dose-dependent toxic liver damage ( hepatitis , cholestasis and even liver failure ). The first reports of suspected liver inflammation caused by medicinal products containing celandine extract were made in 1993 and announced in 1998. See the following table for the chronology of the side effect reports and their accompanying circumstances:

Authority - institution - company Chronology of side effect reports and their accompanying circumstances
Commission E of the former Federal Health Office In May 1985, Commission E of the former Federal Health Office published a positive monograph on celandine (Chelidonii herba), in which the herb and its preparations were approved for the treatment of spasmodic complaints in the biliary tract and gastrointestinal tract, with contraindications, Side effects and interactions were reported as "not known".
Drugs Commission of the German Medical Association (AkdÄ) In October 1998 the Medicines Commission informed the German medical profession that eight cases of hepatitis had been registered in their database since 1993 after the administration of preparations containing celandine extract, and that a suspicion of a medicinally toxic cause must therefore be expressed.
Medicines Commission of the German Medical Association In November 2002, the drug commission of the German medical profession had over 60 reports on chelidonium preparations in its database for adverse drug reactions (ADRs), more than 40 relating to “liver damage”. Fatal liver failure was reported in one case. Since more effective substances are available for the effects claimed by chelidonium preparations, the Medicines Commission advised against the use of celandine extracts.
Federal Institute for Drugs and Medical Devices (BfArM) In April 2008, the Federal Institute for Drugs and Medical Devices ordered that the approval of celandine-containing drugs, for which more than 2.5 milligrams of total alkaloids (calculated as chelidonin ) per daily dose can be administered according to the dosage instructions in the package insert, be revoked. If the dosage instructions in the package insert are between 2.5 micrograms and 2.5 milligrams, detailed warnings should be included in the package insert. The Steigerwald Arzneimittel company filed an objection to this order and did not adapt the instructions for use of its gastrointestinal drug "Iberogast" accordingly.
Steigerwald Arzneimittel In May 2008, the Steigerwald company announced that the recommended daily dose of 60 "Iberogast" drops had taken 0.25 milligrams of total alkaloids.
European Medicines Agency EMA In its assessment report published in September 2011, the European Medicines Agency (EMA) certified that celandine and the preparations made from it generally had a negative benefit-harm ratio and recommended that the group of people to be treated and the amount of recommended daily doses be restricted. This also applies to daily doses below 2.5 milligrams of total alkaloids.
Bayer takes over Steigerwald In July 2013, the phytopharmaceutical manufacturer Steigerwald and with it its product “Iberogast” was taken over by Bayer AG.
Swissmedic In January 2018, the Swiss Medicines Institute, Swissmedic, included a warning about liver damage such as acute liver failure and hepatitis in the package insert and in the specialist information for the celandine-containing drug "Iberogast".
Bayer Vital GmbH In September 2018, the manufacturer Bayer Vital GmbH also added detailed warning notices to the “Iberogast” package insert.

In June 2019, the Cologne public prosecutor's office started investigations against unknown persons. The reason was a death that occurred in the spring of 2018, which was linked to the consumption of "Iberogast". It was questionable whether this death could have been prevented by earlier information on the package insert.

Kiel 1980, p. 40): Grintwurtz is very warm and contains poisonous juice. It has such a dark and bitter poison in it that it cannot be of any benefit to human health, because if it were to bring health to man in one respect, it would on the other hand only cause him a greater illness inside. When someone eats or drinks it, it ulcers and harms them internally, and so at times causes pain and discomfort in man, both in solution and in digestion. But if you eat, drink or touch something unclean, which causes ulcers in the body, take old lard, add plenty of grint root juice to it, crush it so that it dissolves in a bowl. Then he smeared himself with the sebum and will heal.
