Key Constituents

Caffeoylquinic acids (chlorogenic acid and cynarin)[3, 6]

The principal choleretic, hepatoprotective and antioxidant constituents.

Chlorogenic acid
Flavonoids (luteolin glycosides)[3]

Antioxidant constituents of the leaf.

FlavonoidsGlycosidesLuteolin
Sesquiterpene lactones (cynaropicrin)[3]

The bitter principle that stimulates digestion.

Sesquiterpene lactonesSesquiterpenes
Sesquiterpene lactones (lactucin, lactucopicrin)[4, 11, 12]

Bitter, centrally-active constituents responsible for the sedative and pain-relieving effects; isolated lactucin and lactucopicrin produced analgesia comparable to ibuprofen and sedation in rodent tests.

Sesquiterpene lactonesSesquiterpenes
Lactucarium (the dried milky latex)[11]

The historical medicinal preparation, concentrating the active lactones.

Pharmacological Actions

Choleretic / cholagogue (bile flow)[3, 13]

Choleretic - stimulates bile flow to aid fat digestion

Digestive aid[3, 13]

Digestive aid for dyspeptic complaints - indigestion, bloating and fullness

Hepatoprotective (liver support)[1, 2, 3, 7, 11]

Hepatoprotective / liver support (protects liver cells and may aid their regeneration)

Lipid-lowering[3, 9, 10, 12, 14, 15]

Lipid-lowering - helps reduce cholesterol (an RCT showed lower total and LDL cholesterol and higher HDL; a Cochrane review judged the overall evidence promising but not yet convincing)

Analgesic (pain relief)[4, 6, 11, 12]

Mild analgesic / anodyne for pain (lactucin and lactucopicrin act on the central nervous system) - in mice these compounds produced analgesia comparable to ibuprofen

Antitussive (cough suppressant)[5, 11]

Antitussive for an irritable, dry cough (traditional)

Anxiolytic / calming[11]

Calming for nervous tension and restlessness

Sedative / sleep support[4, 6, 7, 8, 11]

Sedative for sleeplessness / insomnia - lactucin and lactucopicrin showed sedative activity in animal models

Safety, Cautions & Contraindications

Safety note[13]Caution

Because it stimulates bile flow, artichoke is contraindicated in bile-duct obstruction and should only be used under medical supervision if you have gallstones.

Safety note[13]Caution

As a member of the daisy family (Asteraceae), it can cause allergic reactions in sensitive people; use in pregnancy and breastfeeding is not recommended.

Safety note[12]Info

Can be unsafe in large amounts or if harvested too early: overdose can cause sweating, fast heartbeat, dilated pupils, dizziness, ringing in the ears, vision changes, heavy sedation, breathing difficulty and, in extreme cases, death.

Safety note[11, 12]Caution

Its sedative effect can add to that of sedatives and alcohol - avoid combining and do not use before driving. As a daisy-family (Asteraceae) plant it can cause allergy; avoid in pregnancy and breastfeeding.

Botanical Description

Tall, thistle-like perennial herb with large, deeply lobed, silvery-green leaves, spiny in wild forms but usually spineless in cultivated globe artichoke. The plant produces a large, edible immature flower bud (the 'artichoke heart' of cuisine) which, left to mature, opens into a striking violet-blue thistle flower.[3]

Height: 1-2 m
Habit: Tall, robust, thistle-like perennial herb
Leaves: Large, deeply lobed, silvery-green, spiny in wild forms
Flowers: Large violet-blue thistle-type flower head, harvested immature as the edible artichoke bud
Stem: Stout, ridged, branching
Root: Deep, fleshy taproot
Fruit: Achene with a feathery pappus
Flowering Period: Summer, if buds are left unharvested

Tall, bristly biennial herb with a milky latex throughout, and prickly-edged, often blue-green leaves that tend to twist to align edge-on with the sun ('compass plant' habit). Small, pale yellow, dandelion-like flower heads are borne in loose branched clusters atop a tall, spiny-stemmed flowering stalk.[11]

Height: 1-2 m
Habit: Tall, bristly biennial herb; low rosette in year one, tall flowering stem in year two
Leaves: Prickly-edged, often blue-green, sometimes twisting edge-on to the sun
Flowers: Small, pale yellow, dandelion-like flower heads in loose branched clusters
Stem: Tall, spiny, exuding milky white latex when cut
Root: Taproot
Fruit: Small achene with a feathery pappus
Flowering Period: July-September (second year)

Habitat

Native to the Mediterranean region; cultivated widely as a vegetable and medicinal crop in warm-temperate climates on rich, well-drained soil.[3]

Grows on dry waste ground, roadsides, hedgerows and disturbed soil; native to Europe, North Africa and Western Asia and naturalised in North America.

Harvesting

For medicinal use, the leaves are picked before flowering, when caffeoylquinic acid (chlorogenic acid/cynarin) content is highest, and dried; the edible flower bud is separately harvested young, before the flower opens.[3]

Parts: Leaf
Season: Before flowering

The milky latex is traditionally collected by scoring the flowering stem and letting the exuded sap dry into lactucarium; the aerial parts (leaf and stem) are also cut and dried while the plant is flowering.[11]

Parts: Aerial parts and dried latex (lactucarium)
Season: Flowering (second year); latex collected by scoring the stem

Traditional Uses

Artichoke leaf has a long Mediterranean folk history as a bitter digestive and liver remedy, used to stimulate bile flow and ease dyspeptic complaints such as indigestion, bloating and fullness, and as a traditional hepatoprotective 'liver tonic'; modern standardised leaf extracts are also studied for supporting healthy cholesterol levels.[3]

Wild lettuce has a long folk history, reflected in the name 'opium lettuce', as a mild sedative and analgesic remedy for insomnia, nervous tension and pain, and as an antitussive for irritable dry cough, its dried latex (lactucarium) once used as a milder, non-addictive alternative to opium.[11]

Preparations

Standardised extract[3]

Dried leaf extract standardised to caffeoylquinic acid (chlorogenic acid/cynarin) content, taken as capsules or tablets for digestive and lipid support.

Infusion[11]

Dried aerial parts infused in hot water as a traditional calming, sleep-supporting tea.

Lactucarium (historical)[12]

Dried milky latex, the classic historical preparation, used cautiously given its overdose toxicity.

Dosage

Standardised extract[3]

Clinical studies commonly use extracts providing around 300-640 mg dried leaf extract, up to three times daily. Educational reference only, not a prescription.

Infusion[12]

Because of documented overdose toxicity (rapid heartbeat, heavy sedation, breathing difficulty), only conservative traditional herbal doses should be used and this herb should not be self-dosed at concentrated or extract strength without professional guidance. Educational reference only, not a prescription.
