Liver and Digestion: 4 Bitter Extracts from the Italian Tradition

Which extract is right for you?
Plant Extracts Rooted in Tradition
Long before pharmacies, the healers of the Mediterranean turned to certain plants to accompany everyday rhythms of eating and digestion. Olive leaf, milk thistle, artichoke and dandelion are among the longest-recorded herbs in European folk medicine — Hippocrates wrote about olive leaves, and Hildegard of Bingen mentioned milk thistle in her 12th-century writings. Today they remain core herbs of traditional phytotherapy.
At Viworo, we choose Fluid Extracts 1:1 for you — meaning one part of plant material yields one part of extract, without heavy concentration. The natural spectrum of constituents is preserved, just as it has been in Italian herbalism for centuries. The extracts are made in an Italian partner laboratory and curated by our family business in Lana, South Tyrol, since 1989.

1
Olive Leaf
Olea europaeaThe olive tree has been the symbol of the Mediterranean since antiquity. Egyptians, Greeks and Romans cherished not only its fruits but also its leaves — Hippocrates wrote about olive leaves in his texts, and old Roman healers passed down the tradition. In southern Italian folk culture, olive leaves are among the oldest household remedies still remembered by grandmothers today.
Fresh olive leaves are particularly rich in oleuropein, a natural polyphenol also found in olive oil. It is this molecule that gives the extract its characteristic bitter-grassy note. In traditional phytotherapy, fresh leaves are especially valued because they preserve the full natural spectrum of the plant's constituents.
Traditional use: Diluted in water or unsweetened herbal tea. In the Mediterranean tradition, taken in cycles of several weeks — often around seasonal transitions.
2
Milk Thistle
Silybum marianumMilk thistle is one of the most thoroughly studied plants of European herbalism. It grows wild across the Mediterranean basin — you'll find it in fallow fields throughout central and southern Italy, and Sicily. Its common name comes from a Christian legend: the white veins on its leaves are said to have been left by a drop of the Virgin Mary's milk. Hildegard of Bingen mentioned it in her writings as early as the 12th century.
The active compounds sit mainly in the ripe seeds. The flavonoid complex known as silymarin — composed of silybin, silydianin and silychristin — is among the most extensively researched plant constituents in modern phytotherapy. In Italian herbal tradition, milk thistle is one of the classic herbs accompanying the body's everyday work.
Traditional use: Diluted in a little water, ideally before meals. Typically taken in cycles of several weeks.
3
Artichoke
Cynara scolymusThe artichoke is one of the oldest cultivated plants of the Mediterranean. In Italy it is also cuisine, identity, regional pride: from Roman carciofo romanesco to the violet variety of Tuscany, from the Sicilian mammola to the spiny variety of Piedmont. But beyond the kitchen, its leaves hold a place of honor in Italian herbalism — think of any classic Italian bitter aperitif, where artichoke leaf extract has been a key ingredient for generations.
The large, serrated leaves contain the most distinctive bitter compound: cynarin. This molecule gives artichoke its unmistakable taste — that fresh-bitter note that has accompanied Mediterranean cuisine for centuries and lives on in every Cynar and every Italian digestif.
Traditional use: Classically after a rich meal, in a glass of water. Often taken in cycles of two to three weeks in the Italian rural tradition.
4
Dandelion
Taraxacum officinaleDandelion — the familiar yellow flower of meadows everywhere — is also one of the most underrated herbs in Western phytotherapy. In northern Italian country kitchens, its young leaves traditionally went into spring salads, picked straight from the fields. In medieval European folk medicine, it was used as a spring cycle herb. Italians call it dente di leone ("lion's tooth"), the same root the English name keeps from old French.
Both the root and the leaves are rich in bitter compounds, particularly taraxacin. That distinctive bitterness gives the plant its character and is the reason dandelion belongs to the erbe amare — the bitter herbs of the Italian tradition — alongside milk thistle and artichoke.
Traditional use: Typically as a spring cycle of four to six weeks. Taken in water or an unsweetened herbal tea.

Why Viworo
Frequently Asked Questions
What is a Fluid Extract 1:1?
A Fluid Extract 1:1 (Italian: Estratto Fluido) is a traditional form of plant extract from Italian herbalism. One part of plant material yields one part of liquid extract — unlike tinctures (typically 1:5 or 1:10), the 1:1 ratio keeps the natural spectrum of plant constituents more concentrated. Our extracts contain around 30% alcohol as a carrier.
How is a Fluid Extract different from a Mother Tincture?
A Mother Tincture (Tintura Madre) is typically produced at a 1:10 ratio — so much more diluted. A Fluid Extract 1:1 is considerably more concentrated and comes from the classic Italian phytotherapy tradition. Both forms have their place, but at Viworo we work intentionally with fluid extracts because they're closer to traditional Italian herbal practice.
How do I use the extracts?
The traditional approach is 5–10 drops, 2–3 times a day, in a glass of water or an unsweetened herbal tea. The drops can be taken over several weeks as a cycle. Milk thistle and artichoke are traditionally taken before meals; dandelion is classically used as a spring cycle. Always follow the product label and do not exceed the recommended amount.
Are the Viworo extracts organic?
No — our plant extracts are not organic products. We carefully select raw materials from Mediterranean growing regions, following the tradition of Italian herbalism. If you are specifically looking for organic products, you'll find them in our range of essential oils.
Where are the extracts produced?
The Fluid Extracts are made in an Italian partner laboratory following a traditional recipe. At Viworo we choose the plants, control every batch, and ship from Lana in South Tyrol — usually within 24 to 48 hours of your order.
Can I combine several extracts?
In Italian phytotherapy tradition, some plants are classically combined — for example milk thistle and artichoke as the "bitter herbs" of the Mediterranean tradition. If you're unsure, or have existing health concerns, we recommend talking to your doctor, pharmacist or qualified herbalist before starting a longer cycle.
Where do you ship?
We ship throughout the European Union, Switzerland not included. Standard delivery within Italy is usually 24–48 hours; within the EU 3–5 working days. We currently do not ship to the United Kingdom or the United States.
Try them yourself
Our four traditional plant extracts are available individually, in 30 ml or 100 ml bottles. They come to you directly from Lana: dispatched within 24–48 hours, delivery usually in 2–4 working days.
