The risks of exposure are mild due to the low concentration of PAs in coltsfoot, however, regular or excessive consumption of coltsfoot, especially in the form of herbal teas, should be avoided (1). See the section on safety (below) before consuming coltsfoot in herbal formulas. .<\/p>","into_the_heart_of":"[caption id=\"attachment_14702\" align=\"alignright\" width=\"600\"]<img class=\"size-medium wp-image-14702\" src=\"https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110600\/Coltsfoot-flowers-Tussilago-farfara-600x400.jpg\" alt=\"Coltsfoot (Tussilago farfara)\" width=\"600\" height=\"400\" \/> Coltsfoot (<em>Tussilago farfara<\/em>)[\/caption]\r\n\r\n<span style=\"font-weight: 400;\">There are some conflicting opinions about the energetics of coltsfoot as it is categorised by some as cooling (2,3) and by others as warming (4). However, this difference of opinion could be explained by the preparation of the herb, since the fresh herb is cooling, whereas the dried herb is more heating (5).<\/span>\r\n\r\n<span style=\"font-weight: 400;\">There is, however, agreement that it is both moistening and drying, depending on the condition being treated (2,3,4,6). In conditions of excessive mucus, coltsfoot will thicken and dry the phlegm and astringe the mucous membranes, whereas dry conditions can be supported by the mucilaginous polysaccharides.\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Coltsfoot contains some constituents in the category of pyrrolizidine alkaloids (PAs), of which there are around 650 different kinds (7). Although PAs are often collectively considered to be toxic, there is a varying degree of toxicity in these constituents from mild to significant, and some are entirely non-toxic (7). <\/span>\r\n\r\n<span style=\"font-weight: 400;\">During the process of breakdown in the liver some types of PAs are converted to toxic byproducts, which can damage the hepatic tissue (8). The main PAs in coltsfoot are the non-toxic tussilagine, tussilaginine, isotussilagine and isotussilagine (7). However, it also contains small amounts of the toxic senkirkine (0.015%) and trace amounts of the toxic senecionine (0.001%) (7). The concentrations of PAs in coltsfoot are thought to be too low to be clinically significant, although the dangers associated with long-term use, even at low doses, are unclear (1). No cases of human toxicity have been linked to the use of coltsfoot at the recommended dosages (1,7). <\/span>\r\n\r\n<span style=\"font-weight: 400;\">Two case reports of toxicity were later determined to be misidentification of a Senecio species as coltsfoot, and a combination of other PA containing herbs ingested at the same time (9).\u00a0 In animal studies exploring toxicity, rats had to be exposed to very high doses of coltsfoot (more than 4% of their diet) before they deve<\/span><span style=\"font-weight: 400;\">loped liver damage, which took between six to twelve months (7)<\/span><span style=\"font-weight: 400;\">. To give context to this, one cup of coltsfoot infusion will contain one part-per-million (PPM*) of total PAs, which is an extremely low exposure (7). PAs are water soluble and will be more highly concentrated in water extracts, whereas oil extracts contain lower concentrations of the potentially toxic PA constituents (7). <\/span>\r\n\r\n<span style=\"font-weight: 400;\">*<\/span><span style=\"font-weight: 400;\">One PPM equates to one microgram (mcg) per gram (5).<\/span>","tradtional_uses":"[caption id=\"attachment_14697\" align=\"alignright\" width=\"600\"]<img class=\"size-medium wp-image-14697\" src=\"https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110547\/Coltsfoot-plants-Tussilago-farfara-600x400.jpg\" alt=\"Coltsfoot (Tussilago farfara)\" width=\"600\" height=\"400\" \/> Coltsfoot (<em>Tussilago farfara<\/em>)[\/caption]\r\n\r\n<span style=\"font-weight: 400;\">Culpeper\u2019s <\/span><i><span style=\"font-weight: 400;\">Complete Herbal<\/span><\/i><span style=\"font-weight: 400;\"> states that the fresh leaves or juice are cooling and drying, and to be used for a hot, dry cough, wheezing and shortness of breath (10).

The condition often becomes chronic with deep, dried mucus that is difficult to expel, and the lungs may be damaged by scar tissue (3). The active constituents support recovery of the bronchial cilia, restore the integrity of the respiratory mucosa and increase immune resistance which can provide relief from the exhausted condition (2,3). These conditions are often accompanied by constricted airways and trapped mucus, in which coltsfoot dilates the bronchi and loosens stagnation, making it easier to cough up any phlegm (18).\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Coltsfoot has antioxidant and antibacterial actions, however alternative herbs with these actions specific to the lungs include <\/span><a href=\"https:\/\/www.herbalreality.com\/herb\/elecampane\/\"><span style=\"font-weight: 400;\">elecampane<\/span><\/a><span style=\"font-weight: 400;\"> (<\/span><i><span style=\"font-weight: 400;\">Inula helenium<\/span><\/i><span style=\"font-weight: 400;\">), <\/span><a href=\"https:\/\/www.herbalreality.com\/herb\/thyme\/\"><span style=\"font-weight: 400;\">thyme<\/span><\/a><span style=\"font-weight: 400;\"> and <\/span><a href=\"https:\/\/www.herbalreality.com\/herb\/aniseed\/\"><span style=\"font-weight: 400;\">aniseed<\/span><\/a><span style=\"font-weight: 400;\"> (<\/span><i><span style=\"font-weight: 400;\">Pimpinella anisum<\/span><\/i><span style=\"font-weight: 400;\">).\u00a0<\/span>\r\n<h3><a href=\"https:\/\/www.herbalreality.com\/herb\/ground-ivy\/#digestive-system\">Digestive system<\/a><\/h3>\r\n<span style=\"font-weight: 400;\">Due to the mucilage content of coltsfoot, it has a demulcent action which can be used to sooth irritations in the GIT and treat inflammatory digestive disorders, especially where there is ulceration (15).

Since the discovery of PAs, which can cause veno-occlusive liver disease in susceptible individuals, the traditional herbal use of the coltsfoot has come into question (23).\u00a0 Prolonged use and high doses should be avoided and limited to 4\u20136 weeks use per year (2,14,28).<\/span>\r\n\r\n<span style=\"font-weight: 400;\">The European medicines agency recommends the maximum duration of two weeks of continuous use (29).\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">In Australasia coltsfoot cannot be legally prescribed for internal use (29).<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Avoid during pregnancy due to potential abortifacient effect and the hepatotoxic pyrrolizidine alkaloids, which can be fatal to the foetus (28). Coltsfoot should not be consumed when breastfeeding due to the hepatotoxic pyrrolizidine alkaloids (28). Coltsfoot should not be taken by children under the age of 18 years old (5). The use of coltsfoot is recommended under the guidance of a qualified medical herbal professional.<\/span>","interactions":"<span style=\"font-weight: 400;\">Coltsfoot should not be taken at the same time as herbs or medications which induce CYP3A, including <\/span><a href=\"https:\/\/www.herbalreality.com\/herb\/st-johns-wort\/\"><span style=\"font-weight: 400;\">St John\u2019s Wort<\/span><\/a><span style=\"font-weight: 400;\"> (<\/span><i><span style=\"font-weight: 400;\">Hypericum perforatum<\/span><\/i><span style=\"font-weight: 400;\">), <\/span><a href=\"https:\/\/www.herbalreality.com\/herb\/schisandra\/\"><span style=\"font-weight: 400;\">schisandra<\/span><\/a><span style=\"font-weight: 400;\"> (<\/span><i><span style=\"font-weight: 400;\">Schisandra chinensis<\/span><\/i><span style=\"font-weight: 400;\">) and epilepsy medications (5). Induction of phase one liver metabolism (specifically CYP3A), speeds the conversion of PAs to the activated toxic pyrroles (5,8). Conjugation of the pyrroles in phase two liver metabolism is the rate limiting step of detoxification, and induction of phase one metabolism increases the potential for hepatic cell injury (8).\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Coltsfoot should not be taken alongside other medications requiring phase two liver metabolism, especially those requiring glutathione conjugation, since PA-induced hepatotoxicity may be more pronounced if the glutathione content in the liver is low (8).\u00a0\u00a0<\/span>\r\n\r\n<span style=\"font-weight: 400;\">Due to the risk of additive toxicity, coltsfoot should not be taken alongside other PA containing herbs or supplements, including boneset, borage, butterbur, comfrey, gravel root, hemp agrimony, and tansy (30).<\/span>","contraindications":"<span style=\"font-weight: 400;\">Coltsfoot should be avoided or only taken under the guidance of a medical herbalist if there is profuse congestion of catarrh of the mucous membranes, since the mucilage may exaggerate the effect of the mucosal discharge (28).

Coltsfoot should not be used by anyone with a history of liver disease due to the potential hepatotoxicity from the pyrrolizidine alkaloids (28). <\/span>","sustainability_image_one":320403,"sustainability_image_two":320404,"faqs":null,"not_suitable_for":["Avoid in pregnancy and lactation","Drug interactions","Contraindications","Toxicity concern","Not suitable for children"]},"featured_image_urls_v2":{"full":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara.jpg",1716,1140,false],"thumbnail":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara-600x600.jpg",600,600,true],"medium":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara-1000x664.jpg",1000,664,true],"large":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara-1300x864.jpg",580,385,true],"banner_image":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara-1600x800.jpg",1600,800,true],"gform-image-choice-sm":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara.jpg",300,199,false],"gform-image-choice-md":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara.jpg",400,266,false],"gform-image-choice-lg":["https:\/\/i.herbalreality.com\/wp-content\/uploads\/2024\/11\/03110555\/Coltsfoot-Tussilago-farfara.jpg",600,399,false]},"post_excerpt_stackable_v2":"","category_list_v2":"","author_info_v2":{"name":"","url":""},"comments_num_v2":"0 comments","_links":{"self":[{"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb\/14694","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb"}],"about":[{"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/types\/herb"}],"version-history":[{"count":4,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb\/14694\/revisions"}],"predecessor-version":[{"id":320416,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb\/14694\/revisions\/320416"}],"acf:post":[{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/posts\/6308"},{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/posts\/178"},{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb\/5819"},{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/herb\/5786"},{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/condition\/150"},{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/condition\/9321"}],"acf:term":[{"embeddable":true,"taxonomy":"sense","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense\/27"},{"embeddable":true,"taxonomy":"sense","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense\/527"},{"embeddable":true,"taxonomy":"sense","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense\/28"},{"embeddable":true,"taxonomy":"sense","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense\/18"},{"embeddable":true,"taxonomy":"sense","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense\/31"},{"embeddable":true,"taxonomy":"writer","href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/writer\/1910"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/media\/14700"}],"wp:attachment":[{"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/media?parent=14694"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/tags?post=14694"},{"taxonomy":"conditions","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/conditions?post=14694"},{"taxonomy":"sustainability","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sustainability?post=14694"},{"taxonomy":"sense","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/sense?post=14694"},{"taxonomy":"western_action","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/western_action?post=14694"},{"taxonomy":"chinese_action","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/chinese_action?post=14694"},{"taxonomy":"ayurvedic_action","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/ayurvedic_action?post=14694"},{"taxonomy":"energetics_action","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/energetics_action?post=14694"},{"taxonomy":"writer","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/writer?post=14694"},{"taxonomy":"region","embeddable":true,"href":"https:\/\/www.herbalreality.com\/wp-json\/wp\/v2\/region?post=14694"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
