Liver Complex with Milk Thistle – What's Behind These Supplements?
Products labeled as “Liver Complex” are becoming more and more popular. You’ll find them in drugstores, pharmacies, and online shops as capsules, drops, or tablets—often combined with botanical ingredients like 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? If you’re interested in the liver from the perspective of Hildegard’s teachings, you’ll find a first overview on this page.
What is a Liver Complex?
The term “Liver Complex” isn’t a protected designation. Different manufacturers use it to describe products that combine several botanical ingredients traditionally used in connection with the liver. Most of the time, these are dietary supplements—not medicines. That means: These products can’t make health claims beyond the officially approved so-called health claims.
The formulas can vary a lot from one manufacturer to another. Some products focus mainly on milk thistle, while others use blends of several plant extracts, vitamins, or secondary plant compounds. If you’re interested in traditional approaches to liver health, check out our article on traditional insights from Hildegard von Bingen on the liver.
Milk Thistle – the Most Well-Known Ingredient
Milk thistle (Silybum marianum) is a plant native to Central Europe and part of the aster family. You can recognize it by its distinctive white-veined leaves and purple flower heads. The fruits and seeds of milk thistle contain a compound called silymarin, which is made up of different flavonolignans.
Milk thistle has been used in European herbal traditions for centuries. In modern supplements, the extract from the seeds is used, since it’s especially rich in silymarin. Currently, there are no approved health claims for milk thistle extracts at the EU level from the European Food Safety Authority (EFSA).
Milk Thistle Ingredients at a Glance
| Ingredient | Where Found | Note |
|---|---|---|
| Silymarin | Seeds and fruits | Complex of flavonolignans |
| Silybin | Main component of silymarin | Secondary plant compound |
| Flavonoids | Leaves and fruits | Plant pigments |
| Fatty oils | Seeds | Contains linoleic acid |
| Bitter substances | Whole plant | Typical for asters |
Other Common Ingredients in Liver Complex Products
Besides milk thistle, many liver complex products include other botanical ingredients. Artichoke extract, dandelion root extract, turmeric, choline, and various B vitamins are often found. Choline is especially relevant, since there’s an approved EFSA health claim for it: Choline supports normal fat metabolism and helps maintain normal liver function. If you’re interested in botanical foods and their ingredients in general, you’ll find more background info 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 sold as dietary supplements are subject to strict regulations in Germany and the EU. They can’t make claims about preventing, treating, or curing diseases. That’s a key difference from medicines, which require clinical studies and official approval procedures.
Health-related claims on dietary supplements must be approved by the EFSA and come from the official health claims list. Many botanical ingredients—including milk thistle extract—currently don’t have such approval for specific health benefit claims.
What Manufacturers Can and Can’t Say
| Allowed Statements (Examples with EFSA Approval) | Not Allowed Statements (Examples) |
|---|---|
| “Choline supports normal liver function” | “Cleanses the liver” |
| “Vitamin B12 supports normal energy metabolism” | “Detoxifies the body” |
| “Zinc supports normal immune system function” | “Boosts your defenses” |
| “Vitamin E helps protect cells from oxidative stress” | “Balances your metabolism” |

Milk Thistle in the History of Botany
Milk thistle has a long history in European botany. It was already described and cultivated in ancient Greece and the Middle Ages. In folk tradition, it was considered one of the best-known plants, especially when it came to 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 how it was used back then.
Today, the plant is the subject of numerous scientific studies, with research mainly focusing on the compound silymarin. However, current findings still don’t allow for any final, universally valid statements about specific health effects in humans.

Traditional Plants in Nutrition According to Hildegard von Bingen
Hildegard von Bingen described a wide variety of plants and their uses in nutrition in her works. Among the herbs she mentioned—which are still discussed today in connection with the liver—are wormwood and greater celandine. The organic wormwood tonic is one of the traditional products that ties into these traditions. Wormwood is one of the bitter herbs Hildegard mentioned in her work Physica. Greater celandine also appears in historical plant descriptions in the context of gallbladder and digestion.
