A side-by-side comparison of two medicinal plants — every documented constituent, action, use, safety note and cited source, assembled automatically from the Omnia Sana database.
At a glance
Chickweed and Common coltsfoot: they share 3 indicated uses (arthritis / joint pain, inflammation (general), skin irritation); 1 pharmacological action in common.
Evidence face-off — shared uses
| Condition | Chickweed | Common coltsfoot | Verdict |
|---|---|---|---|
| Arthritis / joint pain | 2/10 | 1/10 | Comparable evidence |
| Inflammation (general) | 2/10 | 2/10 | Comparable evidence |
| Skin irritation | 1/10 | 1/10 | Comparable evidence |
Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
Key Constituents
Contribute to antioxidant and anti-inflammatory activity.
Minor constituents; large amounts of fresh herb have anecdotally been linked to mild gastrointestinal upset, possibly related to saponin content.
Nutritive constituents supporting its traditional use as a wild edible green.
Hepatotoxic constituents that are the central safety concern for this plant; regulatory limits and PA-controlled/PA-reduced products exist specifically because of these compounds.
Demulcent polysaccharide contributing to the traditional soothing action on irritated airways.

Safety, Cautions & Contraindications
Don’t overdo it as food: some wild-edible-plant research flags chickweed among plants checked for oxalic acid / nitrates—fine in normal amounts, but “huge daily servings” aren’t a smart idea for everyone. (Guil et al., 1997). Kidney stones / high-oxalate diets: if you’re prone to calcium-oxalate stones, treat chickweed like other higher-oxalate greens—moderation. (Guil et al., 1997). Possible stomach upset in large amounts (nausea/diarrhea reported anecdotally; some sources link this to saponins and “too much fresh herb”). (Singh et al., 2022). Pregnancy / breastfeeding: because good human data is limited, many herbal references advise sticking to food amounts or avoiding medicinal dosing unless guided by a professional. (Singh et al., 2022).
Duke (2002) notes that chickweed has primarily folkloric (score f) activity as a demulcent, emollient, and depurative. Its main medicinal applications are external — including soothing inflamed skin, eczema, and itching. No strong clinical evidence supports specific internal medicinal uses. The plant contains flavonoids and coumarins. It is considered generally safe as a dietary green and in topical preparations, though no standardized dosages are established (Duke, 2002).
Safety notes (contraindications, interactions, pregnancy/lactation notes, adverse effects, dose-duration cautions) Important: Coltsfoot naturally contains pyrrolizidine alkaloids (PAs)—plant chemicals that can damage the liver and may increase cancer risk with enough exposure (EMA, 2021; Kopp et al., 2020).
Because of this, European regulators set very strict limits for PA exposure from herbal products (EMA, 2021).
Many safety-focused herbal references recommend avoiding homemade/internal coltsfoot use, unless the product is specifically made to be PA-controlled / PA-reduced (EMA, 2021).
Avoid internal use if you are pregnant or breastfeeding, have liver disease, or for children—these groups are treated as “sensitive” in PA risk guidance (EMA, 2021).
Medication caution: if you take medicines that stress the liver (some prescription drugs can), it’s extra important to avoid unregulated PA exposure (general PA risk logic; consult a clinician) (EMA, 2021).
Topical use may still carry PA considerations; EMA discusses limits and recommends use only on intact skin for PA-containing products (EMA, 2021).
Duke (2002) provides clinical support (score 2) for coltsfoot's anti-inflammatory and expectorant effects, explaining its traditional use in bronchitis and coughs. However, the plant contains hepatotoxic pyrrolizidine alkaloids (PAs), and Duke notes a carcinogenic score (1) — a critical safety concern. Commission E has placed restrictions on coltsfoot use, recommending maximum internal use of 4–6 weeks per year and avoiding use in pregnancy, lactation, and in children under 12. Duke rates its overall safety as low (+) and emphasizes that preparations free of PAs are preferred (Duke, 2002).
External Ids
Botanical Description
Low, sprawling annual herb (Caryophyllaceae) forming mats, with weak trailing stems bearing a single line of fine hairs running up one side, switching sides at each leaf node - a key identification feature. Leaves are opposite, ovate and pointed. Tiny white, star-shaped flowers have five deeply notched petals that appear as ten, followed by a small capsule.[1]
Low perennial herb notable for flowering before its leaves appear: solitary, bright yellow, dandelion-like flower heads emerge on scaly pinkish stalks in very early spring, followed later by large, hoof-shaped (heart-shaped with angular teeth), white-woolly-backed leaves arising directly from the creeping rhizome.[11]
Habitat
Native to Europe, now a cosmopolitan weed found worldwide, growing in disturbed ground, gardens, cultivated land and waste places, tolerating cool, moist conditions.[1]
Grows on disturbed, damp or clay-rich waste ground, riverbanks, railway embankments and bare soil; native to Europe, North Africa and temperate Asia and naturalised in North America.[11]
Harvesting
The whole aerial plant is gathered fresh, ideally in spring or autumn when most tender, and used fresh or dried.[1]
Flowers are gathered in very early spring before the leaves appear; leaves are gathered later in the season once expanded. Given the plant's pyrrolizidine alkaloid content, harvesting from a positively confirmed patch (not a look-alike) and preferring PA-tested commercial material for internal use is strongly advised.[2]
Traditional Uses
Chickweed has a long European and North American folk-medicine tradition as a cooling, soothing emollient for itchy, inflamed skin conditions such as eczema, and as a nutritious wild spring green. Modern phytochemical review confirms broad anti-inflammatory and antioxidant activity, though clinical trial evidence remains limited.[1, 11]
Coltsfoot has an ancient European and Chinese tradition, reflected in its Latin name (tussis = cough), as an expectorant and demulcent remedy for coughs, bronchitis and irritated airways; because of its pyrrolizidine alkaloid content, contemporary use is restricted to short courses of PA-controlled preparations under regulatory limits (see contraindications).[1, 2, 12]
Preparations
Crushed fresh herb, or an infused oil/salve, applied to itchy, irritated or inflamed skin.
Commercially prepared, pyrrolizidine-alkaloid-tested extract or syrup, the only form recommended for internal use given the plant's natural PA content.
Dried flower or leaf infused in hot water; traditional but subject to strict duration/PA-content limits under EU herbal regulation.
Dosage
EU regulatory guidance restricts internal use to PA-controlled preparations. The EMA public statement on unsaturated pyrrolizidine alkaloids records a maximum daily intake for internal use of 1 microgram of PAs for at most 6 weeks per year, or 0.1 microgram per day with no duration limit; for cutaneous use the limits are 100 micrograms for at most 6 weeks per year, or 10 micrograms without a duration limit. Not for use in pregnancy, breastfeeding, or children. Note that these are limits on PA intake, not a herb dose — no EMA monograph exists for Tussilago farfara, so there is no official posology for the herb itself. Educational reference only, not a prescription — consult a qualified practitioner and prefer tested commercial products.
