Liver Complex with Milk Thistle – What's Behind These Dietary Supplements?
Products under the term "liver complex" are growing in popularity. You can find them in drugstores, pharmacies and online shops in the form of capsules, drops or tablets – often combined with herbal ingredients such as milk thistle, dandelion, artichoke or turmeric. But what exactly is a liver complex, which ingredients are typically included, and what should you look out for when buying? Anyone interested in the topic of the liver from the perspective of the Hildegard teachings will find a first overview on this page.
What Is a Liver Complex?
The term "liver complex" is not a protected designation. It is used by various manufacturers to describe products that combine several herbal ingredients traditionally associated with the liver. In most cases, these are dietary supplements – not medicinal products. This means: no health-related promises may be made for such products that go beyond approved so-called health claims.
The compositions vary considerably from manufacturer to manufacturer. While some products rely on milk thistle as the main ingredient, others contain mixtures of several plant extracts, vitamins or secondary plant compounds. Those interested in traditional approaches to the liver can also read our article on traditional impulses according to Hildegard von Bingen relating to the liver.

Milk Thistle – The Best-Known Ingredient
Milk thistle (Silybum marianum) is a plant native to Central Europe from the daisy family (Asteraceae). It is recognisable by its characteristic whitish-veined leaves and purple-red flower heads. The fruits and seeds of milk thistle contain an active compound complex called silymarin, which consists of various flavonolignans.
Milk thistle has traditionally been used in European herbal medicine for centuries. In modern dietary supplements, the extract from the seeds is used, as this is particularly rich in silymarin. For approved health-related claims at EU level, there are currently no approved health claims from the European Food Safety Authority (EFSA) for milk thistle extracts.
Overview of Milk Thistle Constituents
| Constituent | Occurrence | Note |
|---|---|---|
| Silymarin | Seeds and fruits | Complex of flavonolignans |
| Silybin | Main component of silymarin | Secondary plant compound |
| Flavonoids | Leaves and fruits | Plant pigments |
| Fixed oils | Seeds | Contains linoleic acid |
| Bitter compounds | Entire plant | Typical of the daisy family |
Other Typical Ingredients in Liver Complex Products
In addition to milk thistle, many liver complex products contain further herbal ingredients. Commonly found are artichoke extract, dandelion root extract, turmeric, choline and various B vitamins. Choline is particularly relevant here, as an approved EFSA health claim exists for this nutrient: choline contributes to normal fat metabolism and the maintenance of normal liver function. Those generally interested in plant-based foods and their constituents will find further background information on our blog.
| Ingredient | Botanical name | Plant part used | Approved EFSA claim |
|---|---|---|---|
| Milk thistle | Silybum marianum | Seeds/fruits | No |
| Artichoke | Cynara scolymus | Leaves | No |
| Dandelion | Taraxacum officinale | Root, leaves | No |
| Turmeric | Curcuma longa | Rhizome | No |
| Choline | – | – | Yes – normal liver function |
Liver Complex as a Dietary Supplement – Legal Classification
Products placed on the market as dietary supplements are subject to strict regulations in Germany and the EU. They may not bear any statements attributing to them an effect in the prevention, treatment or cure of diseases. This fundamentally distinguishes them from medicinal products, for which clinical studies and approval procedures are required.
Health-related claims on dietary supplements must be approved by EFSA and must come from the so-called health claims list. Many herbal ingredients – including milk thistle extract – currently have no such approval for specific health benefit claims.
What Manufacturers May and May Not Say
| Permitted statements (examples with EFSA approval) | Non-permitted statements (examples) |
|---|---|
| "Choline contributes to normal liver function" | "Cleanses the liver" |
| "Vitamin B12 contributes to normal energy metabolism" | "Detoxifies the body" |
| "Zinc contributes to the normal function of the immune system" | "Strengthens the immune defences" |
| "Vitamin E contributes to the protection of cells from oxidative stress" | "Harmonises the metabolism" |

Milk Thistle in the History of Herbal Medicine
Milk thistle has a long history in European herbal medicine. It was already described and cultivated in ancient Greece and in the Middle Ages. In folk tradition, it was regarded as one of the best-known plants of all when it came to the liver and gallbladder. Historical herbals from the 16th and 17th centuries, such as the herbal book by Hieronymus Bock, contain detailed descriptions of milk thistle and its use at that time.
Today the plant is the subject of numerous scientific investigations. The focus of research is primarily on the active compound complex silymarin. The findings to date do not yet permit any conclusive, universally valid statements about specific health effects in humans. Those interested in the liver from the perspective of traditional practices will find supplementary information in the article on liver compresses – application and background.
Traditional Plants in Nutrition According to Hildegard von Bingen
Hildegard von Bingen described a wide variety of plants and their use in nutrition in her works. Among the herbs mentioned in her writings that are still discussed today in connection with the liver are wormwood and celandine. The organic wormwood tonic is one of the traditional products that draws on these traditions. Wormwood is one of the bitter herbs that Hildegard mentioned in her work Physica. Celandine also appears in the context of bile and digestion in historical plant descriptions.
