Drainage with tea: The 5 most effective herbs in traditional medicine

When the body feels heavy and swollen, when rings press on fingers or shoes suddenly feel tight in the evening—many people first think of water retention. What many don’t know: even in medieval monastic medicine and in Hildegard of Bingen’s herbal knowledge, certain plants were specifically used to support the body’s natural balance. The good news: this centuries-old wisdom can still be easily integrated into everyday life today in the form of herbal tea. In this article, we introduce you to the five herbs that have long been valued in traditional medicine for their diuretic properties—and explain how you can use them as a soothing tea ritual for yourself.

What lies behind the desire for drainage? Knowledge from nature and tradition

Our body is largely made up of water—and that’s a good thing. Water is the most important component of every body cell; it transports nutrients, regulates temperature, and is involved in almost every metabolic process. But sometimes this delicate balance is disturbed: a diet high in salt, little exercise, hormonal fluctuations, or long periods of sitting can contribute to fluid accumulating in the tissues. The result is an unpleasant feeling of heaviness that many people know and that can noticeably harm their quality of life.

In naturopathy, this phenomenon is viewed holistically. Instead of focusing on a single symptom, overall well-being is the priority. Hildegard of Bingen, the great universal scholar of the 12th century, described numerous herbs and their traditional uses in her works—always embedded in a comprehensive understanding of nature, humans, and balance. Her writings are still considered an important source of European herbal knowledge and are experiencing a remarkable renaissance in modern naturopathy. Hildegard of Bingen products

Herbal teas are one of the most accessible and pleasant ways to incorporate traditional plant knowledge into everyday life. They warm you, smell good, provide moments of calm—and at the same time bring valuable plant compounds that have been appreciated in folk medicine for generations. Important to note: herbal tea is not a medicine but a pleasure and companion in the context of a conscious lifestyle. The principle is: Add rather than omit—with every cup, add something good instead of going without.

Diuretic herbal teas have been used for centuries in European and Asian folk medicine – not as remedies, but as soothing companions to a conscious, nature-connected lifestyle.

Hildegard of Bingen wrote in her work "Physica": "The herbs are given to humans so that they may know and use them, for God has placed power in them." This understanding of plants as natural companions – not as cure-alls – still shapes traditional European herbal medicine today.

The 5 traditional diuretic herbs in profile

Not all herbs are the same, and traditional plant knowledge distinguishes very precisely between different species and their characteristic properties. The following five plants have earned a special reputation in the history of natural medicine – they are repeatedly mentioned in herbal books, monastery pharmacies, and traditions from all over Europe and beyond as valuable companions for feelings of heaviness and water retention. Each of these plants has its own story, its own taste, and its own tradition.

It is worth considering these herbs not only as functional ingredients but also as cultural heritage – as part of a body of knowledge passed down through generations and now gaining new attention in modern natural medicine all Bitterkraft products. Those who drink tea connect with a long line of people before us who enjoyed the same plants in the same steaming cups.

Please note that the following list is based on traditional use and does not contain medical claims. For health concerns, we always recommend consulting a doctor or naturopath. The herbs presented here are intended as a complement to a healthy lifestyle – as a soothing ritual that enriches your daily life.

These 5 herbs are traditionally used for diuretic purposes:

• Nettle (Urtica dioica): One of the best-known wild herbs in Europe – valued in folk medicine since the Middle Ages as a "spring cure" and traditionally known for its invigorating properties.
• Dandelion (Taraxacum officinale): The golden-yellow "weed" from the garden was already cultivated in medieval monastery gardens and is considered one of the most valued spring herbs in European natural medicine.
• Birch leaves (Betula pendula): Traditionally used for centuries in Nordic and German folk medicine – the birch is considered a symbol of spring and renewal.
• Horsetail (Equisetum arvense): One of the oldest plants on earth, known since antiquity and playing an important role in traditional naturopathy for generations.
• Goldenrod (Solidago virgaurea): Historically valued in monastic medicine and mentioned in the famous herbal book by Hieronymus Bock from the 16th century – traditionally regarded as a valuable medicinal herb.

What is behind these herbs?

All five plants contain a variety of secondary plant compounds – including flavonoids, essential oils, bitter substances, and mineral salts. These ingredients are the subject of scientific research, even though traditional use predates any modern analysis. In naturopathy, the interaction of these substances is considered "synergistic": Not a single active ingredient, but the entire plant mixture makes the tea a valuable companion.

Herbal tea as a daily ritual: How to integrate tradition into your everyday life

Perhaps the greatest advantage of herbal tea is its simplicity. No complicated equipment, no elaborate preparation – a handful of dried herbs, hot water, and a few minutes of calm are enough. But this very simplicity holds a deep wisdom long known in monastic medicine: The ritual of drinking tea is just as valuable as the tea itself. Pausing, breathing, warming up – this is just as much part of traditional herbal practice as the plant in the cup. Fasting products

For a traditionally oriented herbal tea cure, naturopathy generally recommends drinking two to three cups daily over several weeks – preferably at fixed times to help the body get used to the ritual. Morning, shortly after waking up, has a long tradition as a good starting time. This way, the herbs unfold their effect as part of a conscious morning routine that addresses both body and mind. In the evening, more calming blends are suitable that can support falling asleep – here it is advisable to avoid stimulating diuretic herbs. Sleep and relaxation products

Another traditional tip from monastic medicine: favor herbs of the season. Nettle and dandelion in spring, birch leaves in early summer, goldenrod and horsetail in autumn – just as nature has its own rhythm, we can also adapt our herbal ritual to the seasonal cycle. Hildegard von Bingen always spoke of the connection between humans and the earth’s rhythm as the foundation of well-being. This principle is as relevant today as it was in the 12th century.

The daily tea ritual – two cups in the morning, consciously sipped – is not only a method of herb intake in traditional natural medicine but also a moment of mindfulness that can strengthen both body and mind.

Preparation tips from monastic medicine:

Water temperature: For delicate leaves and flowers (birch, dandelion), water at about 85–90 °C is recommended to preserve the fine essential oils. Harder parts like horsetail can be briefly boiled.

Steeping time: Let steep covered for 8–10 minutes – covering is important to prevent valuable ingredients from evaporating with the steam. This advice can already be found in medieval herb books.

Blends: Traditionally, herbs were often combined to complement flavor and effect. A classic: nettle + birch leaves + a pinch of peppermint for freshness.

Tea consumption in Europe has a history spanning thousands of years. In medieval monasteries, herb gardens (so-called "Hortuli") were an integral part of daily life – monks and nuns deliberately cultivated medicinal and spice plants, whose traditions still influence natural medicine today, such as Hildegard von Bingen products. Hildegard’s herb lists included over 200 plants, among them many diuretic herbs still used today.

Nettle, Birch, and Dandelion: Three Herbs with a Long History

Among the five herbs presented, three stand out particularly for their historical significance and their prevalence in European folk medicine: nettle, birch leaves, and dandelion. These three plants have been known not only in German herb gardens and pharmacies for centuries – they also appear in the writings of medieval scholars, in folk traditions from the Alpine region, and in the monastery pharmacies of the Benedictines and Cistercians. They are, one might say, the classics among diuretic herbs.

The nettle is considered one of the most complete wild herbs in Europe. Already in the Middle Ages, it was valued not only as a food plant but also as an important part of spring cures that were meant to restore well-being after the long, vegetable-poor winter. Its iron content, mineral salts, and characteristic slightly earthy taste made it a favorite among herbalists. Hildegard of Bingen mentioned nettle in her works as a plant with diverse properties that, when used properly, can benefit people. Intestinal and digestive products

The dandelion is today mainly known as a yellow "weed" in meadows – but its history as a medicinal plant goes back at least to the Middle Ages. Arab physicians of the 10th century described it, and in 14th and 15th century Europe, it was a staple in every monastery pharmacy. Especially the leaves and root were traditionally used; spring dandelion was considered particularly valuable. The birch, in turn, is deeply rooted in Northern European symbolism – as the first tree to sprout in spring, it is seen as a symbol of renewal. Its young leaves were traditionally gathered and brewed as tea, especially in German, Scandinavian, and Eastern European folk medicine.

Nettle, dandelion, and birch leaves are among the most traditional European herbs – their use in folk medicine can be traced back over 1,000 years.

Plant compound profile of the three classics:

Nettle: Rich in flavonoids (including quercetin, rutin), silica, iron, magnesium, and potassium. Also contains chlorophyll and various organic acids.

Dandelion: Contains bitter substances (taraxacin, taraxacerin), inulin, flavonoids, potassium, and essential oils. Especially the leaves and root are rich in these secondary plant compounds.

Birch leaves: Known for their high flavonoid content (hyperoside, myricetin), saponins, essential oils, and tannins. Potassium-rich plants like birch are especially valued in traditional herbal medicine.

Horsetail and goldenrod: The underestimated treasures of naturopathy

While nettle, dandelion, and birch are now also known to a wider audience, horsetail and goldenrod still lead a somewhat more hidden existence – although both plants have had a firm place in traditional naturopathy for centuries. It is worth taking a closer look at these two herbs because their history is at least as impressive as that of the better-known diuretic herbs. Liver products from Bitterkraft

The horsetail (also called tin herb or duwock) is one of the evolutionarily oldest plants on Earth – it existed over 300 million years ago when dinosaurs roamed the Earth. Today, it grows in delicate form along paths, meadows, and moist places. In folk medicine, it was especially known in Central Europe: the famous herbal book by Sebastian Kneipp from the 19th century explicitly mentions it, and it also has its place in Sebastian medicine as well as the Hildegard tradition. Horsetail is particularly known for its exceptionally high silica content – a property that makes it a unique herb.

The goldenrod, on the other hand, shines every late summer and autumn with its golden-yellow panicles – and already has a healing effect on the mind. Its scientific name Solidago virgaurea derives from the Latin "solidare" (to strengthen, to heal), which already reflects its historical appreciation in the name. In the 16th century, Hieronymus Bock described it as a "noble herb," and in the 17th and 18th centuries, it was one of the most expensive medicinal plants in Europe and was imported from America before it was recognized that a native species possessed the same properties. Today, it grows again in many herb gardens and naturopathic pharmacies. Immune system products

In a historical herbal book from the 16th century (Hieronymus Bock, "Kreutterbuch", 1539), it says about goldenrod: "This herb is exceedingly good for wounds … and comforts tired limbs." Its use at the time as a strengthening and cleansing herb reflects a tradition that extends into modern naturopathy – even though the interpretation has changed.

Special features of horsetail and goldenrod:

Horsetail: With a silica content of up to 10% of its dry mass, it is one of the richest plants in silica. Additionally, it contains flavonoids (including isoquercitrin), alkaloids, and organic acids. In naturopathy, it is traditionally valued for connective tissue, skin, and nutrient supply.

Goldenrod: Contains diterpenes, saponins, flavonoids (rutin, quercetin), and essential oils. In traditional European herbal medicine, it is considered one of the most important herbs for well-being in autumn and is used in many classic herbal blends.

What both plants have in common is their rooting in a European herbal tradition that does not focus on a single symptom but considers the whole person. Those who add horsetail or goldenrod to their herbal tea add something to their daily ritual that generations before them already valued – and that alone can be a good feeling. Combined with nettle or birch leaves, both herbs create aromatic, harmonious tea blends that delight both in taste and ritual.

Mix, enjoy, repeat: Your personal diuretic tea routine

Now that you know the five most important traditional diuretic herbs, the practical question arises: How do you best incorporate them into your daily life? The answer lies in the combination of tradition and personal taste. In monastic medicine, herbs were rarely used individually but mostly in carefully balanced blends – a principle shared by modern naturopathy. Ready-made herbal tea blends have the advantage that the proportions are already balanced; those who prefer to mix themselves can emphasize their favorite flavors.

If you want to consume 1.5 to 2 liters of fluid daily, you can wonderfully take part of it in the form of herbal tea. It is important to also drink enough pure water because herbal teas do not replace water – they complement it. A proven ritual from naturopathy: a large glass of water in the morning, followed by two cups of herbal tea, one cup at noon, and another in the afternoon – this way, you easily reach the recommended fluid intake while enjoying the benefits of traditional herbal medicine.

For those who want to engage more deeply with naturopathy and the Hildegard tradition, a seasonal tea cure is recommended: one week each in spring (nettle, dandelion), summer (birch), and autumn (horsetail, goldenrod). This type of seasonal herbal use corresponds to the rhythm thinking of old herbal medicine and gives the ritual a deeper meaning. Of course, you can enjoy the herbs all year round – but consciously following the seasons has its own charm and brings a valuable dose of mindfulness to everyday life. Hildegard von Bingen products

The combination of daily 1.5–2 liters of fluid, a fixed tea ritual, and seasonal herbal selection corresponds to the basic principle of traditional European monastic medicine: balance through rhythm and nature.

Three classic tea blends from tradition:

Spring Freshness (March–May): Nettle 40% + Dandelion 40% + Peppermint 20% – invigorating, slightly bitter, refreshing.

Summer Breeze (June–August): Birch leaves 50% + Nettle 30% + Lemon balm 20% – mild, harmonious, lightly lemony.

Autumn Strength (September–November): Goldenrod 40% + Horsetail 40% + Thyme 20% – spicy, strong, warming.

Finally, a note: Herbal teas are valuable companions to a healthy lifestyle, but they are no substitute for sufficient sleep, a balanced diet, and regular exercise. In holistic naturopathy, these areas are considered inseparably connected. If you introduce herbal tea as a daily ritual, you may find that it enriches not only your physical well-being but also your relationship with nature and yourself – and this, as Hildegard von Bingen knew, is the most important aspect of any herbal practice.
