Diuretic Foods According to Hildegard: These Vegetables and Fruits Promote Excretion

Water in the tissues, a feeling of heaviness and fullness – many people know this sensation, especially in warmer seasons or after hearty meals. The medieval abbess and naturalist Hildegard of Bingen (1098–1179) devoted herself intensively to the question of how certain foods can influence the inner balance of a person. In her preserved healing knowledge, known as monastic medicine, vegetables and fruits played a central role – not only as food but as a conscious means of caring for the body. Those seeking traditional ways to support their well-being with natural foods will find in Hildegard’s work a fascinating and still vibrant source of knowledge.

Hildegard’s View on Water, Juices, and Balance in the Body

Hildegard of Bingen developed her healing knowledge based on the ancient theory of the four humors, which she combined with mystical and spiritual elements. In her main works Physica and Causae et Curae, she described in detail how foods influence the so-called bodily fluids – blood, phlegm, yellow bile, and black bile. An excess of watery or mucous fluids was considered by her to be the cause of heaviness, sluggishness, and discomfort. Certain vegetables and fruits were traditionally used in monastic medicine to restore inner balance and gently support the body’s natural elimination processes.

Particularly interesting is Hildegard’s nuanced consideration of foods: she distinguished between foods that generate warmth and dryness and those that increase coldness and moisture. For people who often feel heavy and bloated, she recommended herbs and vegetables with a “dry” and “warm” quality. This classification remarkably aligns with modern findings about secondary plant compounds such as flavonoids and bitter substances, which have been valued in natural medicine for centuries.

The concept of drainage was not purely a physical process for Hildegard. She understood it as part of a holistic cleansing process that touches body, mind, and soul equally. Food was never neutral for her – it was either healing or harmful, depending on the person’s constitution and the season. This holistic perspective makes Hildegard’s teachings still attractive today for many people who do not want to reduce health to individual symptoms but want to consider the whole person.

Hildegard writes in the Physica: “Man should know the nature of his foods, for what he eats, he becomes.” – This statement illustrates how closely Hildegard linked nutrition and well-being and how relevant this idea still is today.

Diuretic Vegetables Especially Valued by Hildegard

Among the vegetables traditionally considered especially valuable in Hildegard medicine, fennel holds an outstanding position. Hildegard devoted extraordinary attention to fennel and described it as one of the best vegetables for humans overall. It was used for centuries in monastic medicine to promote general well-being and support the feeling of inner lightness. Fennel was considered “warm and dry” – ideal for those wanting to free themselves from heaviness and water retention. Today, it is a fixed component of naturopathic nutritional concepts.

Celery was also among the plants Hildegard explicitly recommended. Celery – whether stalk or celeriac – contains a lot of water but also a variety of secondary plant compounds known in traditional natural medicine for centuries. Hildegard described celery as a plant that “cleanses” internally and frees the body from excess. In modern plant-based nutrition, celery is also valued as a diuretic food – an example of how traditional knowledge and contemporary findings can go hand in hand.

Parsley was ubiquitous in Hildegard’s garden and was considered not only a kitchen herb but a true medicinal plant. Hildegard recommended parsley in various preparations – as an herb, in soups, or as part of herbal blends. She especially valued the root of parsley, attributing to it special power in dealing with excess moisture in the body. To this day, parsley is a traditionally used home remedy employed in many European cultures to naturally support kidney function – always within the framework of a balanced diet and healthy lifestyle.

These diuretic vegetables are known in Hildegard medicine:

• Fennel: Valued in monastic medicine as a “warming and drying” vegetable, fennel has been traditionally used for centuries and is historically known for supporting general well-being.
• Celery: Both stalk and celeriac are considered cleansing in the Hildegard tradition; rich in water and secondary plant compounds, used for centuries in monastic kitchens.
• Parsley: Historically one of Hildegard’s most valued medicinal herbs, especially the root was traditionally used in connection with water elimination.
• Asparagus: Known in medieval herbal knowledge for its “draining” properties; traditionally used as a spring vegetable for internal cleansing.
• Nettle: Valued as a wild vegetable in Hildegard’s herb garden, nettle has been regarded in European natural medicine for centuries as a classic diuretic herb.

Fennel is considered one of the most valuable vegetables in Hildegard medicine – it was traditionally used for centuries to support inner balance and promote general well-being.

What is behind the diuretic effect of these vegetables?

Many of the vegetables described by Hildegard contain secondary plant compounds such as flavonoids, essential oils, and organic acids. These substances have been known in traditional natural medicine for centuries and are listed in modern herbal books and naturopathic standard works. Their traditional reputation as diuretic and cleansing foods has secured them a firm place in European monastic medicine – knowledge that is being rediscovered and appreciated today in natural medicine.

Fruit Varieties from Hildegard’s Garden with Elimination-Promoting Properties

Besides vegetables, fruit also played an important role in Hildegard’s nutritional teachings – but with limitations. The abbess was not uncritical toward fruits: many fruit varieties eaten raw she described as “heavy for the stomach” or “moist.” Nevertheless, she explicitly recommended some selected fruits and in certain preparations. The quince was one of her favorite plants – raw or cooked, as quince paste or infusion, it was described as particularly valuable for general well-being. Hildegard appreciated the astringent, drying quality of quince, which she understood as an antidote to excessive moisture in the body. BitterKraft Original

Especially interesting is Hildegard’s recommendation of the mulberry. In her work, she described the mulberry as a fruit suitable both for healthy people and those with ailments – provided it is consumed in moderation. The dark mulberries contain a variety of polyphenols and were traditionally classified in medieval healing knowledge as blood-purifying and elimination-promoting. Today, mulberries are experiencing a renaissance in naturopathic nutritional counseling – not least because their antioxidant and secondary plant compound content attracts scientific interest.

The blueberry is also mentioned in Hildegard’s tradition. It was attributed a cleansing effect on blood and tissues – a concept widespread in medieval monastic medicine. Hildegard recommended small amounts of blueberries, preferably in summer when the fruits are ripe and the body’s inner heat is strongest. The traditional knowledge of the healing power of blueberries has been preserved in European natural medicine to this day: whether as fresh fruit, juice, or extract – it is one of the most valued native medicinal fruits.

The quince is Hildegard’s secret fruit tip: as one of the few fruits she wholeheartedly recommended, it symbolizes the principle of “drying and warming” – the basic principle of all diuretic foods in Hildegard medicine.

In the monastery, quinces were processed into puree, juice, and dried bread. These preparations were considered especially digestible and were repeatedly mentioned in monastic writings of the 12th and 13th centuries as means of internal cleansing – an early evidence of the importance of food as care for well-being.

These fruit varieties are traditionally used in the Hildegard tradition to promote elimination:

• Quince: Hildegard’s “favorite fruit” – used both raw and cooked in monastic medicine, considered a traditional means to promote inner balance.
• Mulberry: Known in medieval herbal knowledge as blood-purifying and elimination-promoting, rich in polyphenols and valued for centuries in European natural medicine.
• Blueberry: Traditionally used for internal cleansing, it is one of the best-known native medicinal fruits and has been documented in European medical history since antiquity.
• Pear: Unlike apples, classified by Hildegard as less “moist”; traditionally described as a mildly digestible fruit with elimination-supporting properties.

How Hildegard’s Nutritional Knowledge Can Be Applied Today in Everyday Life

The beauty of Hildegard’s teachings is their everyday practicality. Most of the foods she recommended are not exotic rarities but vegetables and fruits that we can find in any supermarket or farmers’ market. It is not about following strict diets or completely avoiding certain foods. Hildegard’s approach was always holistic: integrating more of the good into everyday life – the principle of “adding instead of omitting.” Fasting products

Practically, this can look like: a fennel salad for lunch, a nettle soup for dinner, parsley water or tea made from dried mulberry leaves in between. Hildegard recommended taking food consciously and with gratitude – the spiritual element was inseparably connected to physical care for her. Those seeking inspiration in natural medicine today will find in this centuries-old knowledge a surprisingly modern message: conscious eating, seasonal foods, and respect for the forces of nature are not fashionable trends but traditional healing knowledge.

For those who want to delve deeper into Hildegard’s nutritional teachings, a combination of reading her original works (available in modern translations) and consulting experienced naturopaths trained in the tradition of monastic medicine is recommended. Hildegard’s knowledge unfolds its power best when it is understood not as a set of rules but as a living invitation – an invitation to make one’s own nutrition more conscious and connected to nature. Complementary support through high-quality natural products based on Hildegard’s medicinal plant knowledge can enrich this path. Gut and digestion products

Hildegard’s nutritional teachings are not a program of deprivation – they invite you to consciously integrate more of the right foods into everyday life. Fennel, celery, parsley, quince, and mulberry are the stars of a kitchen traditionally associated with inner lightness and well-being.

Tips for everyday integration according to Hildegard:

Morning ritual: A glass of lukewarm water with fresh parsley or fennel slices can be a conscious start to the day – a ritual that had a fixed place in monastic healing.

Observe seasonality: Hildegard repeatedly emphasized the importance of seasonal eating. Asparagus in spring, blueberries in summer, celery in autumn, and fennel in winter – nature sets the rhythm.

Prepare with awareness: Hildegard recommended preparing food not in haste but with calm and gratitude. This aspect of mindfulness is a timeless part of her healing knowledge.

Complementary herbs: Those who want to deepen Hildegard’s knowledge can additionally use bitter tonics or herbal extracts based on traditional recipes – as a complement to conscious nutrition, never as a substitute. BitterKraft Original

Anyone who wants to seriously explore Hildegard’s knowledge should not overlook the spiritual dimension. For the abbess, health was not merely a physical state – it was an expression of harmony between humans and creation. Food was a gift of nature to be used with respect and wisdom. This attitude can be understood today as an invitation to view one’s own nutrition not as a burdensome duty but as a daily opportunity for self-care. In this sense, Hildegard’s legacy is far more than a list of medicinal plants – it is a philosophy of life that continues to inspire with its depth and relevance. Immune system products
