Nature is full of treasures for our health, and this is especially true for urinary problems! Certain plants have specific antiseptic properties for the urinary tract. Their active principle is released directly into the urine where it exerts a local antibacterial action.

Among these plants, two stand out: bearberry, a historical reference in urinary phytotherapy, and heather, a milder and better tolerated, but also slightly less known, alternative: coriander.

Coriander, also known as Arab parsley or Chinese parsley, is an aromatic plant of the Apiaceae family, known since antiquity for its medicinal virtues. While it is now ubiquitous in our kitchens, coriander was already mentioned in Egyptian papyri 1,550 BC among medicinal plants, and traditional Chinese and Ayurvedic medicine have used it for millennia to treat digestive, respiratory, and urinary disorders.

Unlike bearberry and heather, which are used almost exclusively for their urinary properties, coriander is a versatile plant that deserves its place in the prevention of urinary tract infections thanks to its triple mechanism of action: antiseptic, diuretic, and anti-inflammatory.

It has a rich composition of active ingredients
Coriander owes its therapeutic properties to a remarkably rich chemical composition. Its seeds and leaves contain essential oils, the main component of which is linalool, a terpene with powerful antimicrobial properties. It also contains flavonoids (quercetin, apigenin), phenolic acids, and tannins.

Coriander seeds, used in phytotherapy, are particularly concentrated in linalool and α-pinene, which explains their superior effectiveness to leaves for medicinal use, although both parts of the plant are beneficial.

Coriander's triple mechanism of action

Coriander acts along three complementary axes that make it an interesting ally in the management of urinary tract infections:

1. Targeted antibacterial action
Laboratory studies have shown that coriander essential oil and its extracts have significant antibacterial activity against the main bacteria responsible for urinary tract infections: Escherichia coli, Staphylococcus aureus, Proteus vulgaris, and Salmonella.

Another in-vitro study revealed that coriander seeds are among the Indian spices capable of combating bacteria responsible for urinary tract infections. More interestingly, coriander could increase the effectiveness of antibiotics when used in conjunction with medical treatment, suggesting a synergistic effect.

Coriander's antibacterial compounds act by disrupting the bacterial cell membrane and inhibiting their growth, without destroying beneficial flora, unlike antibiotics.

2. Diuretic and detoxifying effect
Another very interesting mechanism of coriander is its ability to stimulate diuresis, i.e., urine production, which promotes the mechanical elimination of bacteria present in the bladder and urinary tract. This natural action prevents pathogenic germs from settling permanently.

Coriander also has documented detoxifying properties, especially for the elimination of heavy metals (lead, mercury, aluminum) via urine. Thus, by promoting general detoxification of the body, it indirectly helps strengthen the immune system.

3. Anti-inflammatory action
The flavonoids and phenolic acids contained in coriander also exert an anti-inflammatory action that helps soothe inflammation of the bladder lining. This property is particularly useful for reducing the burning, irritation, and pain sensations that accompany episodes of cystitis.

What does science say?

We must be transparent: unlike cranberry, which has dozens of clinical trials in humans, coriander has not been the subject of rigorous clinical studies specifically dedicated to urinary tract infections in humans. The evidence we have comes mainly from in vitro (laboratory) studies and centuries of traditional use in Asian medicine.

However, the available pharmacological data are encouraging and consistent with traditional use. Several studies have demonstrated:

• The antimicrobial properties of coriander essential oil against uropathogens
• Its diuretic effect in animals
• Its anti-inflammatory and antioxidant properties

Precautions and contraindications

Although food coriander is generally very well tolerated, certain precautions are necessary for therapeutic use:

Main contraindications:

• People on anticoagulants: coriander contains vitamin K, which promotes blood clotting. It is therefore not recommended for people taking anticoagulant medications (warfarin, AVK), as it could reduce their effectiveness.
• Prolonged high doses: excessive or prolonged consumption of concentrated coriander (extracts, essential oil) can lead to nervous, digestive, and kidney disorders. Always respect recommended dosages and do not exceed recommended treatment durations.
• Pregnant and breastfeeding women: while food coriander is safe, the use of essential oil or highly concentrated supplements should only be done with medical advice.
• Allergies: some people may be allergic to coriander or plants of the Apiaceae family (celery, parsley, fennel, dill). In case of an allergic reaction (rash, itching, breathing difficulties), stop consumption immediately.

Recommended synergistic combinations

Coriander gains effectiveness when combined with other plants:

• Coriander + Cranberry: this is the ideal combination. Cranberry prevents bacterial adhesion, while coriander provides its complementary antibacterial, diuretic, and anti-inflammatory action.

⭐ At Gapianne, intimate health is neither a problem nor a taboo. It's our raison d'être. It is in this spirit that we collaborated with a pharmacist expert in micronutrition to create a food supplement combining coriander and cranberry.

This unique formula combines the antiseptic, diuretic, and anti-inflammatory properties of coriander, capable of supporting toxin elimination, with the preventive effects of cranberry, which prevents bacteria from clinging to bladder walls and reduces the risk of recurrent cystitis. Discover it!

Bearberry, also known as "uva-ursi", is a small plant of the Ericaceae family that grows in mountainous regions of Europe, Asia, and North America. Its leaves have been used since the 18th century in Europe to treat urinary tract infections, and Native American peoples already knew its therapeutic virtues long before this time. Even today, it remains the most prescribed urinary antiseptic plant (especially in Germany), where it is recognized by health authorities.

How does bearberry work?

The secret of bearberry lies in a compound called arbutin (or arbutoside), present in large quantities in its leaves. When you consume bearberry, arbutin follows a specific path in your body: it is first absorbed in the intestine, then transformed by the liver, and finally eliminated by the kidneys in the urine.

This is where the magic happens in the urine: arbutin is broken down into hydroquinone, a substance with powerful antiseptic properties. Hydroquinone acts as a true natural disinfectant directly where the bacteria causing the infection are located.

However, there is an essential condition: this process only works in an alkaline environment, i.e., when the pH of your urine is greater than 7. This is why bearberry should never be combined with vitamin C or cranberry juice, which acidify the urine and cancel its effectiveness.

What do scientific studies say?

Laboratory research has confirmed that hydroquinone derived from bearberry is active against the main bacteria responsible for urinary tract infections: Escherichia coli (the most common, responsible for 80% of cystitis), but also Staphylococcus aureus, Proteus vulgaris, and Pseudomonas aeruginosa.

Clinically, the results are more nuanced. A reference study from 1993 (Larsson) followed 57 women suffering from recurrent cystitis for one year. Those who took bearberry (combined with dandelion) as prevention had no recurrences, while 23% of women on placebo had at least one episode of cystitis. These results are encouraging.

However, a much more recent and larger clinical trial (Moore, 2019) involving 382 women with acute cystitis showed disappointing results: no difference was observed between the bearberry-treated group and the placebo group, either in symptom severity or in the need for antibiotics. This contradiction illustrates the lack of robust and recent evidence regarding the actual effectiveness of bearberry in humans.

Our informed opinion

Bearberry benefits from a strong traditional reputation and official recognition in Germany. Its mechanism of action is well understood and logical. However, recent clinical evidence is contradictory and disappointing. Add to this its toxicity concerns, and the picture becomes nuanced.

We believe that bearberry can be used very occasionally (maximum one week) for prevention in healthy adults, but with the advice of a healthcare professional and under supervision. It should never be the first choice, especially with the existence of safer alternatives like heather or better-validated solutions like cranberry.

Heather is bearberry's botanical cousin. It belongs to the same Ericaceae family and grows abundantly in heaths and siliceous soils across Europe. Two species are used interchangeably in phytotherapy: common heather or calluna (Calluna vulgaris) and bell heather (Erica cinerea), both with very similar properties. Traditionally, heather accompanies or replaces bearberry in the treatment of urinary disorders.

Active ingredients of heather

Heather also contains arbutoside (or arbutin), the same compound as bearberry, but in significantly lower concentrations. This arbutoside is also metabolized into hydroquinone in the urine, where it exerts its antiseptic action against pathogenic bacteria.

But heather doesn't stop there! Its flowering tops also contain flavonoids (quercetin, hyperoside, myricetin) with powerful anti-inflammatory properties, as well as tannins which contribute to its astringent and soothing action on irritated mucous membranes. This richer and more diverse composition explains why heather offers a more comprehensive action than simple antisepsis.

What does science say?

Laboratory studies have confirmed the antiseptic activity of heather against major uropathogenic bacteria: Escherichia coli, Enterococcus faecalis, and Proteus vulgaris. Recent work (Varga 2021) has even shown that heather extracts possess strong antioxidant and antibacterial activity thanks to their 12 phenolic compounds.

Heather also inhibits the growth of pathogenic stomach bacteria without affecting beneficial microflora, which demonstrates an interesting targeted action. The flavonoids it contains act specifically on the bladder walls to reduce inflammation, the source of burning and pain sensations.

However, and this is the major limitation of heather, there are no quality clinical trials conducted in humans to definitively prove its effectiveness in preventing or treating cystitis. Its use is therefore based primarily on tradition, clinical observation by generations of phytotherapists, and encouraging in vitro data.

Our opinion on heather

Heather offers a milder and better-tolerated alternative to bearberry. Used for centuries, well-tolerated by the body and supported by encouraging laboratory results, it is an excellent choice for preventing recurrent cystitis.

Certainly, it lacks rigorous clinical evidence from randomized controlled trials. But in the context of preventive phytotherapy, where the risk is low and where chemical alternatives themselves pose problems (antibiotic resistance), heather fully deserves its place in the natural toolbox against cystitis.

Its combined antiseptic and anti-inflammatory action, good tolerance, and the possibility of using it for longer periods make it a wise choice, either alone for mild urinary disorders, or in combination with other plants (cranberry, orthosiphon) for optimal synergistic action.

In addition to antiseptic plants that release antibacterial substances directly into the urine, there is another equally valuable family of plants in the management of urinary tract infections: diuretic plants. Their action principle is different but complementary.

By increasing the volume of urine produced, they create a true mechanical "washing" of the urinary tract that prevents bacteria from settling and proliferating. Imagine a constant flow of water that cleanses and flushes out: that's exactly what these plants do.

Orthosiphon is a perennial plant native to tropical regions of Southeast Asia, particularly Indonesia and Malaysia. Its nickname "Java tea" comes from the ancient habit of the inhabitants of these regions to consume its leaves as an infusion, just as we drink tea.

It is also called "cat's whiskers" because of its long white stamens that extend beyond its delicate flowers. Used for centuries in traditional Asian medicine to treat kidney and bladder disorders, orthosiphon has gradually conquered the West and is now officially recognized by European health authorities.

Active ingredients that make a difference

Orthosiphon leaves contain a remarkably rich and diverse chemical composition:

• Specific flavonoids such as sinensetin and eupatorin, responsible for its powerful diuretic effect
• Caffeic acid derivatives, especially rosmarinic acid, with anti-inflammatory, anti-infectious, and kidney-protective properties
• A high concentration of potassium salts that contribute to increased diuresis while limiting potassium loss (unlike chemical diuretics)
• Diterpenes that enhance the overall diuretic action

This synergy of compounds explains why orthosiphon does not simply increase urine volume: it acts on several fronts simultaneously.

Solid scientific evidence

Orthosiphon is one of the few diuretic plants whose effectiveness has been scientifically demonstrated rigorously, both in the laboratory, in animals, and in humans.

• Regarding the diuretic effect: a reference study conducted in 2003 proved that orthosiphon administration significantly increases diuresis (the volume of urine produced), as well as the excretion of sodium (Na+) and chloride (Cl-) ions and uric acid. Importantly: unlike chemical diuretics that often cause dangerous potassium loss, orthosiphon limits this potassium loss, making it a particularly safe diuretic.
• Regarding anti-adhesion: recent research has shown that orthosiphon aqueous extract exerts remarkable anti-adhesive action against uropathogenic Escherichia coli. Concretely, this means that orthosiphon prevents bacteria from attaching to the walls of the bladder and urinary tract. This property has been confirmed both in vitro (in the laboratory) and in vivo (in mice). A 2017 study even showed that orthosiphon reduces the expression of E. coli virulence factors, making the bacteria less aggressive.

Clinical trials in humans: here orthosiphon truly stands out. Several quality clinical studies have confirmed its practical interest:

• An observational study of 65 women with cystitis symptoms tested a combination of orthosiphon, hawkweed, and cranberry. After only 3 days of treatment, 72% of participants were completely free of all their symptoms (burning, urgency, pain). The overall symptom intensity score dropped by 90% between the first and fourth day.
• A randomized, double-blind, controlled trial published in 2019 compared a combination containing orthosiphon (associated with goldenrod and ononis) versus placebo in 200 women suffering from acute cystitis. The results are impressive: from the first day of treatment, the treated group showed significant superiority over placebo. On the seventh day, the difference was even more marked, with 78% of patients completely free of their symptoms.
• A non-interventional study on 1,904 patients confirmed these results on a large scale.

Official recognition by health authorities:

The effectiveness of orthosiphon is not just a matter of scientific studies. The main European health authorities have officially recognized it:

• The European Medicines Agency (EMA) recognizes the well-established traditional use of orthosiphon to increase urine quantity and facilitate toxin elimination, as an adjuvant treatment in minor urinary disorders.
• The German Commission E of the Ministry of Health explicitly recommends orthosiphon for flushing the urinary tract in inflammatory or infectious diseases, or in case of kidney stones.
• ESCOP (European Scientific Cooperative on Phytotherapy) recognizes its use for irrigating the urinary tract during inflammation or stones, as well as an adjuvant treatment for urinary tract infections.

How orthosiphon protects you: the triple mechanism

Orthosiphon acts along three complementary axes that make it an excellent choice against urinary tract infections:

1. Mechanical drainage effect: by significantly increasing the volume of urine produced, orthosiphon creates an almost constant flow that literally "washes" the urinary tract. Bacteria are mechanically flushed out before they have time to multiply and cause an infection.
2. Anti-adhesion action: even if bacteria manage to reach the bladder, orthosiphon prevents them from clinging to the bladder walls. Unable to attach, they are simply evacuated during the next urination.
3. Anti-inflammatory effect: orthosiphon compounds soothe inflammation of the urinary mucous membranes, thereby reducing burning sensations, pain, and irritation.

Our opinion on orthosiphon

Orthosiphon is undoubtedly the diuretic plant of choice for the prevention and treatment of urinary tract infections. Unlike many plants whose use is based solely on tradition, orthosiphon benefits from solid scientific evidence from quality clinical trials.

Its triple mechanism of action (diuretic, anti-adhesion, anti-inflammatory), good tolerance, and official recognition by European authorities make it a safe bet. It is particularly effective in combination with other plants such as cranberry or hawkweed. If you only had to remember one diuretic plant to protect yourself from recurrent urinary tract infections, this would be it.

Alongside orthosiphon, two other diuretic plants deserve your attention, especially when used in combination: goldenrod and hawkweed. While their individual scientific evidence is less robust than that of orthosiphon, their centuries of traditional use and excellent tolerance profile make them interesting supplements.

Goldenrod

Goldenrod (Solidago virgaurea) is a perennial plant with clusters of golden yellow flowers that brighten forest edges and clearings in late summer. Its Latin name Solidago means "to make solid" or "to strengthen," in reference to its traditional medicinal virtues.

Goldenrod has a documented triple action: diuretic, anti-inflammatory, and antiseptic. Its composition of flavonoids and saponosides explains its diuretic effect, while its phenolic acids contribute to its anti-inflammatory and antimicrobial properties.

The use of goldenrod for flushing the urinary tract is recognized by the EMA (European Medicines Agency) and the German Commission E. It is also very frequently prescribed in Germany, often in combination with other plants. It is one of the three components of the Aqualibra® specialty that was the subject of a positive randomized controlled trial in 2019.

However, goldenrod suffers from a lack of quality clinical trials evaluating its efficacy alone. The evidence we have comes mainly from studies on combinations of plants, which makes it difficult to assess its specific contribution.

Hawkweed

Hawkweed (Hieracium pilosella), also known as mouse-ear hawkweed due to the shape and hairiness of its leaves, is a small perennial plant with lemon-yellow flowers that grows in dry meadows and sandy soils.

Long recognized as a powerful diuretic, hawkweed was traditionally used to treat water retention, edema, and urinary disorders. Its antiseptic properties, due in particular to its richness in flavonoids and caffeic acid derivatives, make it a natural complement in the management of urinary tract infections.

It was the subject of an interesting clinical study in combination with orthosiphon and cranberry (the one mentioned previously with 72% of patients symptom-free on the third day). While this study does not isolate the specific effect of hawkweed, it nevertheless suggests that it contributes positively to the overall action of the combination.

Our opinion on goldenrod and hawkweed

These two diuretic plants represent interesting complements to orthosiphon or cranberry in an overall preventive strategy. Their traditional use is well established, and their tolerance is excellent.

However, the lack of robust clinical evidence evaluating their individual efficacy leads us to consider them as second-line plants, to be preferred in associated formulas rather than as monotherapy.

They have their place in a global approach to preventing recurrent urinary tract infections, particularly for people who seek to vary the plants used or who wish to benefit from complementary effects (general drainage, anti-inflammatory action, kidney support).

Cranberry (Vaccinium macrocarpon) deserves a special place in this article. We have already covered it in detail in our dedicated article "Cystitis Remedies," where we reviewed the dozens of scientific studies devoted to it. Here is a summary of the essential points to remember.

The best documented scientific efficacy

Cranberry is the anti-cystitis plant with the highest level of scientific evidence. A 2023 Cochrane meta-analysis of 50 studies and 8,857 participants confirmed that it reduces the risk of recurrent cystitis by 30% (relative risk of 0.70). Other studies show reductions of up to 50% depending on the populations studied.

The mechanism: preventing adhesion

The secret of cranberry lies in its type A proanthocyanidins (PACs). These unique molecules prevent Escherichia coli bacteria from attaching to the walls of the bladder and urinary tract. Unable to cling, the bacteria are simply eliminated during urination, before causing an infection.

Important: for prevention only, not treatment

Cranberry is only effective in preventing recurrences. It does not treat an already established acute cystitis. Its action is gradual and requires regular daily intake for several months to achieve a lasting protective effect.

For whom is it effective?

Studies show particularly marked efficacy in:

• Women suffering from recurrent cystitis (≥3 episodes per year)
• Children
• People at risk after a medical procedure

However, efficacy has not been demonstrated in elderly institutionalized individuals, pregnant women, or people with neurogenic bladder.

Our recommendation

For any woman suffering from recurrent cystitis, cranberry should be the first preventive reflex. Its effectiveness is proven, its tolerance excellent (apart from warfarin interaction), and it does not contribute to antibiotic resistance. Combined with good hydration and possibly probiotics, it forms the basis of an effective and natural preventive strategy.

For more details on cranberry (studies, mechanisms, dosage forms, usage tips), we invite you to consult our complete article "Cystitis Remedies."

In phytotherapy, the whole is often greater than the sum of its parts. This is particularly true for urinary tract infections, where the combination of several plants with complementary mechanisms of action yields superior results to those of each plant taken in isolation.

This synergistic approach is based on a simple logic: why settle for a single angle of attack when you can combine several?

Each family of plants acts according to a specific mechanism. By combining them intelligently, we multiply the fronts of action against the bacteria responsible for infections:

1. Anti-adhesion action
2. Antiseptic action
3. Diuretic action

By combining these three types of action, 360-degree protection is achieved: bacteria can neither cling, nor survive in the urine, and are also constantly evacuated by the urinary flow.

Several clinical studies have demonstrated the concrete benefit of these combinations. Here are the combinations that have proven effective:

1. Orthosiphon + goldenrod + ononis (Aqualibra®): the most studied combination

This combination was the subject of a high-quality randomized, double-blind, controlled trial, published in 2019 in the journal Antibiotics. The study compared this combination of plants to a placebo in 200 women suffering from uncomplicated acute cystitis.

The results are remarkable: from the first day of treatment, the plant-treated group showed significant superiority over placebo (p = 0.0086) for reducing typical cystitis symptoms (burning, frequency, urgency). On the seventh day, the difference was even more marked (p < 0.0001), with 78% of patients completely free of all their symptoms (dysuria, pollakiuria, urgency, suprapubic pain).

These figures are all the more impressive as they were obtained in women in acute crisis, not just for prevention. This study demonstrates that a well-designed combination of plants can truly relieve the symptoms of ongoing cystitis, even if it obviously does not replace antibiotics in case of confirmed infection.

2. Hawkweed + cranberry + orthosiphon: 72% success

A French observational study conducted in pharmacies evaluated the effectiveness of a combination of hawkweed, cranberry, and orthosiphon in 65 women presenting with symptoms suggestive of cystitis for less than 48 hours. Participants took the product for three days.

The results are eloquent: after only three days of treatment, 72% of women (47 out of 65) were completely free of all their symptoms: painful urination, frequent urges to urinate in small amounts, cloudy and/or foul-smelling urine, and lower abdominal pain. Among the remaining 28% (18 out of 65), some symptoms persisted but with significantly reduced scores.

Even more impressively: the overall symptom intensity score dropped by 90% between the first and fourth day (p < 0.001).

This study suggests that the combination of these three plants could effectively relieve cystitis symptoms while preserving commensal flora, unlike antibiotics which disrupt bacterial balance.

3. Bearberry + heather: traditional antiseptic synergy

The combination of bearberry and heather is a classic phytotherapeutic practice, passed down through generations of herbalists. The logic is simple: both plants belong to the same botanical family (Ericaceae) and both contain arbutoside, but in different concentrations.

Bearberry, more concentrated in arbutoside, provides a powerful antiseptic action. Heather, milder, complements this action while adding its anti-inflammatory flavonoids and astringent tannins. Together, they create an antiseptic synergy that allows either to use bearberry at a reduced dose (thus limiting its toxicity) or to obtain a more complete effect.

Although this combination has not been the subject of recent controlled clinical trials, its centuries of traditional use and pharmacological logic make it a relevant combination. Many phytotherapists recommend combining the two plants to benefit from the best of both worlds: efficacy and safety.

4. Bearberry + dandelion: prevention validated 30 years ago

Larsson's pioneering study in 1993 tested a combination of bearberry and dandelion leaf for prevention in 57 women suffering from recurrent cystitis. Participants took the treatment for one month, then were followed for one year.

The results, although based on a small sample, are encouraging: none of the women who received the bearberry-dandelion combination experienced a cystitis episode during the one-year follow-up, while 23% of women on placebo had at least one recurrence.

Dandelion, known for its diuretic properties, complements the antiseptic action of bearberry by increasing urinary flow and facilitating bacterial elimination.

Practical tips for benefiting from these synergies

To get the most out of plant combinations:

• Choose formulated products: food supplements that combine several plants in studied proportions are often more effective than improvised homemade mixtures.
• Respect dosages: each plant must be correctly dosed to contribute to the overall effect.
• Hydrate abundantly: whatever the chosen combination, drink at least 2 liters of water per day to allow diuretic plants to function and antiseptics to be properly concentrated in the urine.
• Adjust the duration: in the acute phase (first symptoms), 3 to 7 days are generally sufficient. For prevention, opt for cures of 15 days to 3 months depending on your profile.

The combination of plants is not just a trend in phytotherapy: it is a science-backed strategy that allows for superior results while limiting the doses of each individual plant, thereby reducing the risk of side effects.

Let's be clear from the outset: no plant can replace antibiotics during an active and established urinary tract infection. If you have clear symptoms of cystitis (intense burning during urination, urgent urges, cloudy urine), if these symptoms have lasted for more than 48 to 72 hours, or if they are accompanied by fever, you must consult a doctor. Period.

Urinary tract infection is caused by bacteria (in 80 to 85% of cases, it is Escherichia coli) that have colonized your bladder and are actively multiplying there. To eliminate them effectively and prevent the infection from spreading to the kidneys (pyelonephritis), only antibiotics have proven rapid and reliable efficacy.

Attempting to treat a confirmed cystitis solely with plants risks the infection worsening and becoming complicated. This is neither prudent nor recommended by any serious health authority.

However, plants have two major, scientifically documented uses:

1. Prevention of recurrences.
2. Symptomatic support: during an episode of cystitis (in addition to antibiotics prescribed by your doctor, never as a replacement), certain plants can help relieve unpleasant symptoms (burning, urgency) and accelerate healing by flushing the urinary tract.

Conclusion: adopt a natural and effective strategy against urinary tract infections

Preventing recurrent cystitis is not limited to drinking plenty of water or relying on antibiotics. Nature offers a range of plants with complementary mechanisms: antiseptics (bearberry, heather, coriander), diuretics and draining agents (orthosiphon, goldenrod, hawkweed), or preventive agents (cranberry). Well-chosen and intelligently combined, they allow action on all fronts: mechanical elimination of bacteria, inhibition of their adhesion to urinary walls, and reduction of inflammation.

Among them, coriander stands out for its triple antibacterial, diuretic, and anti-inflammatory effect, while supporting the elimination of toxins and heavy metals, while cranberry remains the scientifically validated reference for preventing recurrences. In synergy, they offer natural and lasting protection, suitable for daily use.

For those who wish to integrate this strategy into their routine, Gapianne offers a food supplement combining coriander and cranberry, formulated with premium quality extracts and packaged in hermetic packaging to preserve the efficacy of the active ingredients. A simple, safe, and practical way to feel protected every day.
