Artichoke
Cynara cardunculus (syn. Cynara scolymus) · the bitter leaf, not the dinner-plate heart
All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.
The artichoke used in supplements is the bitter leaf, not the familiar edible heart. This article explains which plant part is used, the compounds responsible for its bitterness, and what the evidence and regulations actually allow us to say.
This piece covers the botanical source and specific leaf used in supplements, the key chemical constituents responsible for flavour and activity, how regulators view traditional use versus modern claims, and how WellsparQ lists the ingredient on its label. It aims to be clear about what is known and what is not permitted to be claimed for a food supplement.

Most people know the artichoke as the handsome vegetable you eat leaf by leaf, dipping each in butter. The artichoke that goes into supplements is a different part of the same plant, valued for a different reason: not the tender heart, but the large, bitter leaves. This piece explains that distinction, the compounds behind the bitterness, and how carefully the evidence must be read.
The plant and the part that's used
The globe artichoke is Cynara cardunculus (the cultivated form long known as Cynara scolymus), a tall, thistle-like perennial of the daisy family (Asteraceae), domesticated around the Mediterranean ¹. On the plate we eat the immature flower head. In herbal preparations it is the leaf (Cynarae folium) that matters — large, deeply lobed, and markedly bitter ¹².
That bitterness is not incidental. It comes from the leaf's active constituents, and in the long tradition of European herbalism, bitter plants were the ones reached for around meals.
What's in the leaf
Artichoke leaf carries a well-characterised set of plant compounds ¹²:
| Constituent group | Notes |
|---|---|
| Caffeoylquinic acids | Up to ~2% phenolic acids, chiefly chlorogenic acid (3-caffeoylquinic acid) and cynarin (1,5-di-O-caffeoylquinic acid) ¹ |
| Sesquiterpene lactones | ~0.4%, mostly cynaropicrin — the principal bitter principle ¹ |
| Flavonoids | ~0.1–1%, including luteolin glycosides ¹ |
Cynarin is the compound most often named in connection with artichoke, and cynaropicrin is the source of the leaf's characteristic bitter taste ¹. Together they are why standardised artichoke leaf extracts are usually described by their caffeoylquinic-acid content.
Traditional standing and the evidence, read carefully
Artichoke leaf has a long documented history of traditional use, formally recognised by Europe's herbal medicines committee (EMA/HMPC), whose monograph covers Cynarae folium for the relief of mild digestive ("dyspeptic") complaints such as a sense of fullness and bloating ². As with all such designations, this is a traditional-use category for licensed herbal medicines, based on longevity of use rather than modern clinical proof — and it cannot be transferred to a food supplement as a health claim.
Beyond tradition, artichoke leaf has been studied in modern trials, principally around blood lipids. Here the evidence must be handled honestly. A dose–response systematic review and meta-analysis of randomised controlled trials in Phytotherapy Research (2018) examined artichoke leaf extract and reported associations with modest changes in lipid measures, while noting variability between the small studies included ³. A Cochrane review on artichoke leaf extract for high cholesterol concluded only that it might be effective but that better trials were needed — and that review was subsequently withdrawn, a reminder of how unsettled this area remains ⁴. The fair reading is that artichoke leaf is a genuinely interesting, traditionally used bitter herb whose modern clinical evidence is limited and mixed. WellsparQ reports it as evidence, and makes no promise of its own.
How WellsparQ uses it
In WellsparQ's range, artichoke is not a supporting note — it is the star of one formula.
| WellsparQ product | Declared artichoke | Note |
|---|---|---|
| HepaHerb Support | 4,800 mg (leaf extract, fresh-plant equivalent) | "The headline ingredient — nearly five grams of fresh-plant equivalent per capsule" |
Source: WellsparQ Supplements Database. The figure is expressed as a fresh-plant equivalent: the capsule holds a concentrated leaf extract corresponding to that weight of fresh artichoke, a standard and honest way to describe a concentrated botanical. It is disclosed openly rather than buried in a blend, in keeping with the brand's full-label standard. The formula is plant-based and suitable for vegetarians and vegans.
Sensible use
Artichoke belongs to the daisy family, so anyone with a known allergy to plants such as ragweed, marigold or chamomile should take care. Because bitter herbs traditionally act around the biliary system, artichoke is not advised for anyone with gallstones or a bile-duct obstruction without medical advice. Anyone pregnant, breastfeeding or on medication should speak to a GP or pharmacist before use, and take as directed.
