Key Constituents
Responsible for the characteristic astringency.
Antioxidant and anti-inflammatory constituents.
Flax is the richest dietary source of SDG-type lignans, converted by gut bacteria to the mammalian lignans enterodiol and enterolactone; studied for antioxidant and hormone-modulating activity.
The dominant fatty acid of the seed oil (~50-55% of total oil), a plant-based omega-3 studied for cardiovascular and anti-inflammatory effects.
Concentrated in the seed coat; gives flaxseed its demulcent, laxative, bulk-forming action.
Present at low levels; cooking/roasting reduces them to negligible amounts in normal food use - a theoretical concern only at high raw intakes.
Pharmacological Actions
Anti-inflammatory gargle (mild inflammation of the mouth and throat / sore throat)
Agrimonia eupatoria ethanolic extract is cytotoxic to breast, colon, lung and cervical cancer cells and inhibits the PI3K/Akt/mTOR pathway (preclinical/in silico).
Traditional & Indicated Uses
inferred from bitter-tonic action
inferred from anti-inflammatory action
Agrimonia eupatoria ethanolic extract shows dose-dependent cytotoxicity against MCF-7 (breast), HT-29 (colon), A549 (lung) and HeLa (cervical) cancer cells and inhibits the PI3K/Akt/mTOR/COX-2/MMP-2 axis (preclinical).

Safety, Cautions & Contraindications
Traditional-use indication only: if diarrhoea persists longer than 3-4 days, or symptoms of mouth/throat inflammation persist beyond about a week, a doctor should be consulted.
Use during pregnancy and breastfeeding is not recommended, as safety has not been established.
Flaxseeds are safe for most people at recommended food amounts (1–2 tablespoons ground/day). They must be ground or milled to be bioavailable — whole seeds largely pass through the gut undigested. High fibre content may cause bloating, flatulence, and loose stools, especially if fibre intake is increased rapidly without adequate hydration. Flaxseeds contain cyanogenic glycosides (linamarin, linustatin); cooking or roasting reduces these to negligible levels in normal food amounts. Raw seeds in very large quantities are a theoretical concern, but typical use is safe (EFSA, 2017).
Medication interactions: Flaxseed may reduce absorption of oral medications if taken simultaneously — space flaxseed supplementation 1–2 hours from medications. Omega-3 ALA and lignans may mildly enhance anticoagulant/antiplatelet effects; use caution with blood thinners. Some sources suggest caution with hormone-sensitive conditions due to phytoestrogen (lignan) content, though dietary amounts are unlikely to pose risk (Adolphe et al., 2010).
Pregnancy: Food amounts are generally considered safe; high-dose supplements should be discussed with a clinician due to limited safety data.
Duke (2002) rates flaxseed as +++ with clinical evidence (score 2) for antiatherogenic, hypocholesterolemic, laxative, lipolytic (fat-dissolving), and demulcent activities. Flaxseed's omega-3 fatty acids (ALA) and lignans are associated with reduced cardiovascular risk. Commission E approves flaxseed as a laxative and for mucilaginous protection of inflamed gastrointestinal mucosa. Dose: 1–2 tablespoons ground seed with ample water, twice daily. Whole seeds should be chewed or ground for full medicinal effect. Cyanogenic glycosides are present but at safe levels in normal dietary amounts (Duke, 2002).

Botanical Description
Slender, downy perennial herb with a basal rosette of pinnately compound leaves and a single, unbranched, upright flowering stem. The leaflets are toothed, alternating large and small, and silvery-downy beneath. Small, five-petalled, bright yellow flowers are borne closely along a slender terminal spike (raceme), opening a few at a time from the base upwards, giving the old name 'church steeples'. After flowering, small bristly, hooked burrs form that cling to clothing and animal fur for dispersal.[13, 14]
Erect annual herb, slender and often branched near the top, growing 30-80 (up to 100) cm tall from a fine taproot. Leaves are alternate, sessile, narrowly lanceolate to linear, blue-green and entire-margined. Flowers are pale blue (occasionally white or pink), five-petalled and borne on slender stalks in loose terminal cymes. The fruit is a small globular capsule ('boll') that splits into ten compartments, each containing one flattened, glossy, red-brown seed.[5]
Habitat
Native to the Mediterranean region and the Fertile Crescent, cultivated since prehistory for fibre and oil and now grown worldwide in temperate regions with well-drained, fertile soils and a cool, moist growing season; occasionally found as a naturalised escape on waste and cultivated ground.[5]
Harvesting
The flowering aerial parts are cut in summer, at the start of flowering, and dried promptly in a warm, airy, shaded place.[13]
Grown as an annual crop, seed is harvested once the capsules ('bolls') have dried and turned brown, typically in late summer, by cutting or combining the whole plant and threshing out the seed. Whole seed stores well; it should only be ground shortly before use, since the oil in ground seed oxidises and turns rancid quickly.[2]
Traditional Uses
Agrimony has a long folk history as an astringent remedy for mild diarrhoea, as a gargle for sore throats and mild mouth/throat inflammation, and as a mild bitter digestive tonic; it has also been applied topically to minor wounds and skin inflammation. It is officially recognised in the European Union herbal monograph for traditional use in mild diarrhoea and mild inflammation of the mouth or throat.[13, 14]
Flaxseed has a long history of traditional use as a bulk-forming laxative and demulcent for constipation and irritated gut mucosa, and as a poultice for boils and inflamed skin. Modern interest centres on its lignan (secoisolariciresinol diglucoside) and alpha-linolenic acid content, studied for cardiovascular, metabolic and hormone-related outcomes.[2, 4, 5]
Preparations
Whole seed freshly ground (milled) and taken with plenty of liquid, or stirred into food; grinding is needed to make the oil and lignans bioavailable, as whole seeds largely pass through the gut undigested.
Cold-pressed oil taken as a concentrated source of alpha-linolenic acid (omega-3); lacks the fibre and lignan content of the whole ground seed.
Dosage
The EU herbal monograph gives 1.5-4 g of the comminuted herb in 250 mL (or less) of boiling water as an infusion, 2-3 times daily, in adolescents, adults and elderly. As a gargle for mild oral or throat inflammation, 1.5 g in 150 mL of boiling water 2-4 times daily, or a decoction of 3-4.5 g in 250 mL 2-3 times daily. Educational reference only, not a prescription.
The EU herbal monograph gives 1-4 mL three times daily (orally, or as a gargle for oral and throat use). Educational reference only, not a prescription.
Traditional guidance and Duke (2002) suggest 1-2 tablespoons of ground seed with ample water, once or twice daily. Educational reference only, not a prescription.
A randomised placebo-controlled trial titrated flax oil capsules (550 mg alpha-linolenic acid per 1 g of oil) to 12 capsules per day, i.e. up to roughly 12 g of oil daily, over 16 weeks - broadly matching the 1-2 tablespoons (about 10-15 mL) daily often cited for omega-3 intake. That trial was in children and adolescents with bipolar disorder and its primary outcomes were null; it is cited here only as a source for an administered human dose of the oil, not as evidence of benefit. Note the EU herbal monograph on Lini semen covers the SEED, not the oil. Educational reference only, not a prescription.
