Certified Organic Coltsfoot Extract
Also known as: Coltsfoot, Coughwort, Foal's Foot, Tussilago farfara
Overview
Coltsfoot (*Tussilago farfara*) is a perennial herb native to Europe and Asia, recognized for its historical use in treating respiratory ailments and possessing expectorant and anti-inflammatory properties. It primarily contains mucilages, flavonoids, and pyrrolizidine alkaloids (PAs), which contribute to both its therapeutic effects and safety concerns. While traditionally used for conditions like bronchitis and asthma, evidence from human clinical trials is limited, with most studies focusing on animal models or traditional practices. The safety profile is complicated by PAs, which can be hepatotoxic. The herb typically appears in various forms, including teas and extracts, though the standardization of dosages is not established due to insufficient human research.
Benefits
Coltsfoot is primarily noted for its expectorant and anti-inflammatory properties, making it potentially beneficial for individuals with respiratory conditions such as bronchitis and asthma. However, the strength of evidence remains low, as many findings are anecdotal or derived from animal studies rather than robust human trials. Additionally, some evidence suggests that coltsfoot may have antioxidant and immune-stimulating effects, yet these claims are not well substantiated. Traditionally, its use tends to focus on adults suffering from respiratory issues, although safety concerns limit its application in sensitive populations, including children and those with chronic health problems.
How it works
The primary biological action of coltsfoot involves its mucilaginous compounds, which soothe and protect the respiratory tract by forming a protective layer on mucosal surfaces. Flavonoids present in the extract may help reduce inflammation, providing symptomatic relief in respiratory conditions. However, it’s crucial to note that the pyrrolizidine alkaloids associated with coltsfoot can lead to toxic effects, complicating its therapeutic use. While some of these compounds interact with the liver, specific molecular targets and bioavailability pathways remain largely undefined due to limited research.
Side effects
The safety of coltsfoot is a significant concern, primarily due to the presence of pyrrolizidine alkaloids (PAs), which are linked to liver damage and other severe health issues. Common side effects are not well documented because of the lack of human studies, but potential adverse effects include hepatotoxicity with prolonged use and risks of thrombosis. Rarely, severe liver issues can arise, especially in individuals with pre-existing conditions. Moreover, coltsfoot might interact with drugs metabolized by the liver, enhancing their toxicity. It is contraindicated in pregnant and breastfeeding women, patients with liver disease, and those with heart problems. Caution is also advised for children and individuals with chronic health conditions.
Dosage
The dosage of coltsfoot is not well established due to varying individual factors and forms of preparation. Traditional applications, such as teas or infusions, do not have standardized dosages. Long-term use is discouraged because of the toxicity associated with PAs, and short-term use is recommended instead. While specific maximum safe doses have not been defined, the preparation method may impact safety; water extracts could be safer compared to oil extracts, which have higher PA concentrations. Overall, due to insufficient data, timing and method of administration should be approached with caution.
