Botanical Description

Vigorous, low, patch-forming perennial herb spreading rapidly by white, brittle, creeping rhizomes. The leaves are broad and twice-ternate (in threes of threes), with oval, sharply toothed leaflets, borne on long stalks. In summer it sends up hollow, grooved, unspotted green stems topped with flat umbels of small white flowers, typical of the carrot family. The whole plant smells mildly of parsley or carrot when crushed.[1]

Height: 30-100 cm
Habit: Low, mat-forming, rhizomatous perennial herb
Leaves: Broad, twice-ternate, with oval sharply toothed leaflets in groups of three
Flowers: Small white flowers in flat compound umbels
Stem: Hollow, grooved, plain green (never purple-spotted)
Root: Thin, white, brittle, fast-spreading creeping rhizome
Fruit: Small ridged schizocarp typical of the carrot family
Flowering Period: May-July

Habitat & Distribution

A common weed of gardens, hedgerows, shaded waste ground and disturbed soil, often near old dwellings; native to Europe and temperate Asia and widely naturalised elsewhere, where its invasive spreading rhizomes make it a persistent garden weed.[1]

Harvesting

The young leaves and stems are gathered in spring, before flowering, when they are most tender and least bitter; the root can be dug at the same time. Careful identification against poisonous Apiaceae look-alikes (poison hemlock, hemlock water-dropwort, fool's parsley) is essential before harvesting.[1]

Parts: Leaf, Root, Stem
Season: Spring, before flowering

Key Constituents

Polyacetylenes (falcarindiol)[6, 10]

Falcarindiol, a potent COX-1 inhibitor (IC50 0.3 microM), identified as a key anti-inflammatory constituent underlying the plant's traditional anti-rheumatic and analgesic use.

Flavonoids and phenolic compounds[1]

Contribute to the plant's antioxidant activity.

Traditional Use & History

Ground elder has long been used in European folk medicine as a remedy for gout and rheumatic and arthritic joint pain (reflected in the name 'podagraria', from podagra, gout), typically applied as a poultice or taken as a decoction. The young leaves have also been eaten as a spring pot-herb, valued for their nutrient content as well as their medicinal reputation.[1]

Preparations

Decoction[1]

Dried or fresh leaf, stem and root simmered in water as a traditional remedy for gout and rheumatic pain.

Poultice[1]

Fresh leaves crushed or boiled and applied directly to gouty or arthritic joints.

Fresh leaf (culinary/medicinal)[1]

Young spring leaves eaten as a cooked pot-herb, similarly to spinach, continuing the traditional food-medicine use.

Safety, Cautions & Contraindications

Safety note[9, 12, 13, 14]Caution

Generally safe as a food plant when young leaves are harvested. Contains furocoumarins (photosensitising compounds) - handling large quantities in bright sunlight may cause skin irritation. Individuals with Apiaceae allergies should exercise caution. Not recommended in therapeutic doses during pregnancy.

Safety note[12, 13, 14, 15]Info

Duke (2002) does not appear to include a dedicated entry for ground elder (Aegopodium podagraria) in the Handbook of Medicinal Herbs, Second Edition.

Dangerous Lookalikes

Conium Maculatum[16, 17]Fatal
Confused Part: Young leaves and foliage gathered in spring, before flowering.
Confusion Context: Poison hemlock is a carrot-family plant with lacy foliage that can be mistaken for edible umbellifer greens; its alkaloid coniine causes an ascending paralysis that stops breathing, and even a small amount can be fatal. It grows in the same disturbed ground, hedgerows and waste places as ground elder.
Distinguishing Features: Ground elder leaves are in neat groups of three (twice-ternate) with broad, oval, sharply toothed leaflets. Poison hemlock leaves are finely divided, feathery and fern-like - not in groups of three., Poison hemlock has a hairless stem blotched and streaked with purple; ground elder's stem is plain green and grooved, never purple-spotted., Crushed ground elder smells mildly of parsley or carrot; crushed poison hemlock smells foul and musty ('mousy').
Key Test: Check the stem: purple blotches or streaks on a smooth, hairless stem = poison hemlock - do not eat. Ground elder has a plain green grooved stem, broad toothed leaflets in threes, and a mild parsley smell (never mousy).

Reviewed Date: 2026-07-06
Oenanthe Crocata[18]Fatal
Confused Part: Foliage (mistaken for celery or parsley) and roots (mistaken for parsnip), where the plant grows near water.
Confusion Context: Hemlock water-dropwort is probably the most poisonous plant in Britain; its toxin oenanthotoxin causes violent convulsions, and its parsnip-like roots and celery-like leaves have repeatedly been eaten by mistake, often fatally. It grows in and beside water.
Distinguishing Features: Habitat is the first filter: hemlock water-dropwort grows in or right beside water (wet ditches, streams, marshes); ground elder grows in dry gardens, hedgerows and disturbed ground., Hemlock water-dropwort has a cluster of pale, swollen, finger-like root tubers ('dead man's fingers'); ground elder spreads by thin white creeping rhizomes, not fleshy tubers.
Key Test: If the plant is growing in or at the edge of water and has a cluster of swollen finger-like root tubers, treat it as hemlock water-dropwort - do not touch the roots. Ground elder grows in dry ground from thin creeping rhizomes.

Aethusa Cynapium[19, 20]Dangerous
Confused Part: Young leaves and foliage in spring.
Confusion Context: Fool's parsley is a common carrot-family weed of gardens and disturbed ground - named for being mistaken for parsley - that contains toxic polyacetylenes and can cause burning of the mouth, vomiting and neurological effects, especially in children.
Distinguishing Features: Fool's parsley leaves are finely dissected, thin, dark green and fern-like; ground elder leaves are broad, oval, toothed leaflets in neat groups of three - a coarser, very different leaf., In flower, fool's parsley shows three long, narrow bracteoles hanging down beneath each small flower cluster (a 'beard'); ground elder umbels have no such drooping beard., Crushed fool's parsley smells foul and acrid ('mousy'); ground elder smells mildly of parsley or carrot.
Key Test: Finely dissected fern-like leaves with a foul mousy smell - and, if flowering, a drooping three-part 'beard' under each little umbel - mean fool's parsley, not ground elder (which has broad toothed leaflets in threes and a mild parsley scent).

Harvest Readiness

[11]

Part: leaf
Signals: Gather young leaves in spring, before the plant comes into flower, while they are still bright green, glossy and not fully unfurled; leaves gathered after flowering toughen and lose quality., SAFETY: the young spring foliage is exactly the stage confused with the FATAL poison hemlock (Conium maculatum), hemlock water-dropwort (Oenanthe crocata) and fool's parsley (Aethusa cynapium). Confirm identification before gathering - see this plant's Dangerous Lookalikes.
Basis: traditional
Source Quote: The leaves are best harvested before the plant comes into flower.
Species Confirmed: 1
Notes: PFAF also gives a divergent MEDICINAL-herb window - 'The plant is harvested when it is in flower in late spring to mid-summer' - recorded here, not merged: the tender-leaf harvest (before flowering) and the flowering-herb medicinal harvest differ by intended use. Single source -> provisional.

[11]

Part: stem
Signals: Gather the tender leaf-stalks in spring together with the young leaves, before the plant comes into flower., SAFETY: confirm identification before gathering - the young spring plant is confused with FATAL Apiaceae lookalikes (poison hemlock and relatives). See this plant's Dangerous Lookalikes.
Basis: traditional
Source Quote: The leaves are best harvested before the plant comes into flower.
Species Confirmed: 1
Notes: 'Stem' here is the tender leaf-stalk (petiole), gathered with the young pre-flowering leaves; PFAF's leaf statement is the source. Single source -> provisional.
Part: root
Notes: GAP (documented dead end, re-searched 2026-08-15). No reliable phenological source for the ROOT of Aegopodium podagraria. Seams searched and why each failed: Grieve lists 'Parts Used: Herb, root' with no collection stage; King's American Dispensatory has no Aegopodium entry; PFAF carries only unsourced reader comments; a peer-reviewed goutweed review is botanical/chemical with no timing; Madaus gives a collection time for the HERB only ('Die guenstigste Sammelzeit duerfte Juni bis Juli sein') and records that only Gerard-Johnson recommend the root at all; Eat The Weeds states the rhizomes are NOT eaten. Two foraging blogs do give a root season, but their wording is duplicated verbatim from an AI-generated encyclopedia page and they were rejected as unreliable. Next seam: a European flora or a peer-reviewed ethnobotanical survey. SAFETY: the root is confused with the FATAL Oenanthe crocata (mistaken for parsnip) - see Dangerous Lookalikes.
