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
Flower essential oil dominated by linalool and linalyl acetate, the principal compounds behind the calming, anxiolytic and antimicrobial activity.
Antioxidant constituents of the flower.
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
Generally very safe. Essential oil should not be ingested in large amounts. Rarely, contact dermatitis may occur. May potentiate the effect of sedative medications. Avoid therapeutic doses during pregnancy.
Duke (2002) rates lavender as ++ and provides clinical evidence (score 2) for carminative activity, consistent with Commission E approval for nervous stomach disorders and functional abdominal complaints. Additional experimental activities include anxiolytic, antispasmodic, and antiseptic effects. The essential oil demonstrates COX-2 inhibitory and Alzheimer's-relevant properties at the experimental level. Dose: 1–2 teaspoons (4–8 g) dried flowers as tea; 1–3 drops essential oil in a carrier for topical or aromatherapy use. Duke notes that oral lavender oil (Silexan) has clinical evidence for generalized anxiety disorder (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).

Botanical Description
Aromatic, evergreen, woody-based perennial subshrub with narrow, grey-green, felted leaves. Slender flowering spikes carrying whorls of small, tubular, two-lipped violet-blue flowers rise well above the foliage on long, unbranched stalks.[4]
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 the mountains of the western Mediterranean (southern France, Spain, Italy); widely cultivated in sunny, well-drained, often calcareous sites across temperate and Mediterranean climates worldwide.[4]
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 flower spikes are cut as the flowers open, in mid- to late summer, when essential oil content is highest, and dried in a warm, shaded, airy place or distilled fresh for essential oil.[4]
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
Lavender flower has a long Mediterranean and European tradition as a calming, sedative herb for nervous tension, anxiety and insomnia, and as a mild digestive carminative and antiseptic for minor wounds and skin irritation; the essential oil in particular has an extensive modern clinical evidence base for anxiety and sleep support.[4]
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
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
The EU herbal monograph gives 1-2 g of the flower in 150 mL of boiling water as an infusion, three times daily, in adolescents, adults and elderly; a tincture at 2-4 mL three times daily is also listed. The monograph notes that lavender may impair the ability to drive or use machines. Not recommended under 12 years. Educational reference only, not a prescription.
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.

Pairings
Lavender and valerian are both calming herbs used to aid relaxation and sleep; taken together their sedative effects can add up, so while they may help relaxation they can also increase drowsiness — avoid combining with sedative medicines or before driving.[22, 23]
Lavender and lemon balm are both calming herbs used to ease anxiety and aid sleep; taken together their sedative effects can add up, so while they may help relaxation they can also increase drowsiness — avoid combining with sedative medicines or before driving.[22, 24]
Lavender and chamomile are both calming herbs used to ease anxiety and aid sleep; taken together their sedative effects can add up, so while they may help relaxation they can also increase drowsiness — avoid combining with sedative medicines or before driving.[22, 25]
