RenaCHI: Your Kidney Elixir for Natural Excretion, Fluid Balance & Harmony
The kidneys are among the hardest-working organs in your body: They filter about 180 liters of blood daily, remove metabolic waste products, and regulate your fluid balance—and thus your blood pressure. Yet, hardly anyone thinks about their kidneys as long as they function well. Stress, insufficient hydration, an unbalanced diet, and a lack of natural bitter substances can make their work more difficult. Healthy kidneys are crucial for natural excretion and inner balance.
RenaCHI addresses this precisely: Four carefully selected herbs—goldenrod, bearberry leaves, cat’s whiskers leaves, and horsetail, combined in a clear, bitter elixir for your kidneys. These plants have been valued in traditional herbal medicine for their connection to kidney health and fluid balance. Through alcoholic-aqueous maceration, RenaCHI preserves the full spectrum of plant compounds and is enriched with antioxidant vitamin C.
While goldenrod and bearberry leaves are traditionally known for kidney health, cat’s whiskers (also known as Orthosiphon) complements with its valuable plant compounds. Horsetail—rich in silica—completes the formula. Together, they create a harmonious bitter profile that naturally supports your kidneys.
RenaCHI supports you as a daily aperitif before meals: for natural excretion, healthy fluid balance, and inner harmony. Vegan, free from additives, and Made in Germany.
When RenaCHI is particularly beneficial:
- When you want to support your kidneys naturally
- In cases of insufficient fluid intake or unbalanced diet
- As support for natural excretion processes in the body
- During times of increased stress or strain
- For anyone looking to promote their fluid balance and inner harmony
- As a clear, bitter alternative to traditional digestifs or schnapps
Why we developed RenaCHI:
The kidneys work tirelessly in the background, but we often only pay attention to them when problems arise. RenaCHI was created out of a desire to support these vital filter organs preventively. The inspiration: traditional kidney herbs like goldenrod, bearberry, cat’s whiskers, and horsetail, known for centuries for their supportive effects on kidney function and fluid balance—as a clear, bitter companion for natural excretion and conscious nutrition.
Many bitter herb products contain random herb mixtures or primarily alcohol. RenaCHI is different: a targeted formula for kidneys and fluid balance – inspired by traditional monastery recipes.
This is what you should look for when buying a bitter herb aperitif:

How the Herbs in RenaCHI Complement Each Other
Monastic Knowledge Meets Natural Synergy
Traditional herbal medicine already recognized: Healthy kidneys need targeted support, and nature provides special herbs for this purpose. RenaCHI combines four of these traditionally valued kidney herbs in proven synergy: goldenrod herb, bearberry leaves, cat’s whiskers leaves, and horsetail herb. Through alcoholic-aqueous extraction, both fat- and water-soluble plant substances are fully preserved. Naturally, without auxiliary and additive substances, genetically modified raw materials, or animal testing.
The Main Herbs in Detail:
- Goldenrod Herb (Solidaginis gigantea herba)
The golden classic. Goldenrod has been valued for centuries in traditional herbal medicine in connection with kidneys and urinary tract—known for its supportive effect on fluid balance. - Bearberry Leaves (Uvae ursi folia)
The Nordic companions. Bearberry is a classic kidney plant in folk medicine: traditionally used in connection with urinary tract and natural excretion. - Cat’s Whiskers Leaves (Orthosiphonis stam. folia)
The exotic supporters. Cat’s whiskers (also known as Orthosiphon) originates from Asian herbal medicine and is traditionally valued for kidneys and fluid balance. It adds mild spice to the formulation. - Horsetail Herb (Equiseti arvensis herba)
The mineral powerhouse. Horsetail is rich in silicic acid and has been valued since ancient times in connection with excretion and connective tissue. It harmoniously rounds off the herbaceous-clear bitter profile.
Ingredients:
Water, spelt distillate (approx. 17% Vol.), goldenrod herb (Solidaginis gigantea herba), bearberry leaves (Uvae ursi folia), cat’s whiskers leaves (Orthosiphonis stam. folia), horsetail herb (Equiseti arvensis herba), ascorbic acid (Vitamin C)

Your Aperitif Moment for Kidneys & Fluid Balance:
Take a moment each day and consume 15 ml of RenaCHI (that’s 3 teaspoons or ¾ shot glass of 2 cl) before a meal. Let the bitter substances dissolve slowly in your mouth or dilute them with a little water: This way, they unfold their full effect and prepare your body for the upcoming meal.
Tip: Many enjoy RenaCHI about 10–15 minutes before eating, either pure or diluted with still water. This gives the bitter substances time to exert their stimulating effect.

Product Background
The Silent Workers: Why Your Kidneys Deserve More Attention
Have you thought about your kidneys today? Probably not, and that’s exactly the problem. The kidneys are among the hardest-working organs in your body, yet they operate entirely in the background. Every day, they filter about 180 liters of blood, remove metabolic waste products, regulate your fluid balance, and thus also your blood pressure. Without healthy kidneys, your body would become toxic in a very short time.
But precisely because they work so reliably, we hardly pay them any attention until problems arise. Stress, insufficient hydration, an unbalanced diet, and the loss of natural bitter substances from our food can significantly burden kidney function. National and international nutritionists recommend regular support of kidney function for people over 50, as it declines with age.
The Forgotten Connection: Bitter Substances, Metabolism, and Kidney Function
What do bitter substances have to do with the kidneys? More than you might think. Bitter substances not only activate digestion, but they also stimulate the entire metabolism, and the more efficiently your metabolism works, the fewer waste products your kidneys have to excrete. A well-functioning digestive system significantly relieves the kidneys.
Traditional herbal medicine already knew of herbs valued in connection with kidneys and fluid balance: goldenrod, the classic for kidneys and urinary tract, bearberry leaves from folk medicine, cat’s whiskers from Asian tradition, and horsetail, rich in silica. While conventional bitter herb products often contain arbitrary mixtures, RenaCHI specifically combines these four traditional kidney herbs in a coordinated formula.
The Solution: Targeted Kidney Herbs as a Daily Aperitif
RenaCHI relies on alcoholic-aqueous maceration: a method that preserves both fat- and water-soluble plant substances. The result: a complete spectrum of effects that simple powders or teas cannot offer. Enriched with antioxidant vitamin C, it creates a tangy-clear elixir for your kidneys and fluid balance.
The crucial difference: RenaCHI is enjoyed BEFORE the meal – not after. As a true aperitif, it optimally prepares the entire metabolism for food intake and thus indirectly supports kidney function. A small ritual with a big impact – preventive, before problems arise.
What Sets RenaCHI Apart from Other Products:
RenaCHI follows the orthomolecular approach of dr.reinwald vital:
ot isolated individual substances, but natural synergy complexes. The herbs come from controlled sources, and the formula is free from sugar, flavors, and additives. Made in Germany, vegan, and based on traditional recipes – but modernly interpreted for today’s requirements.
Nutritionists recommend a regular intake of bitter substances for people over 50 to support the natural production of digestive juices, which declines with age. RenaCHI makes it easy: 15 ml before the meal – a tangy-clear companion for your kidney function, natural excretion, and inner balance.
Frequently Asked Questions about RenaCHI
The CHI aperitif family from dr.reinwald vital was developed based on the principle of organ systems: Each aperitif specifically supports a particular organ system with traditionally suitable herbs. RenaCHI focuses on kidneys and fluid balance with goldenrod, bearberry leaves, cat’s whiskers leaves, and horsetail. HepaCHI strengthens the liver and gallbladder (dandelion, milk thistle, artichoke), ImmuCHI the immune system (walnut, clove, wormwood), and LymphoCHI the lymphatic system (fir, olive, cranberry). Depending on your needs, you can choose the appropriate CHI aperitif or use them alternately.
Yes! The CHI aperitifs complement each other excellently as they target different organ systems. Many customers use them on a rotational basis: for example, RenaCHI (kidneys) from Monday to Wednesday, HepaCHI (liver) from Thursday to Saturday, and LymphoCHI (lymphatic system) on Sundays. This way, you support different areas of your body. Be sure to adhere to the daily dose of 15 ml per aperitif.
HerbiGOLD is a general herbal bitter aperitif with 14 herbs for digestion, liver, and metabolism – ideal for daily culinary culture and as an “all-rounder.” RenaCHI, on the other hand, is a targeted organ aperitif with 4 specific kidney herbs (goldenrod, bearberry, cat’s whiskers, horsetail) – perfect if you want to specifically support your kidneys and fluid balance. HerbiGOLD = broad, RenaCHI = specific for kidney function.
These four herbs have been valued for centuries in various traditions related to the kidneys and urinary tract. Goldenrod is a classic in traditional herbal medicine for kidneys and fluid balance. Bearberry leaves are traditionally used in folk medicine for the urinary tract. Cat’s whiskers leaves (Orthosiphon) originate from Asian herbal medicine and are known for their supportive effect on fluid balance. Horsetail is rich in silica and has been valued since ancient times in relation to excretion. Together, they form a harmonious synergy for your kidneys.
RenaCHI is a traditional food and not a medication. It naturally supports your kidneys with bitter substances and secondary plant compounds – best used preventively before problems arise. If you have existing kidney diseases, kidney stones, or are taking medication, please consult your therapist. RenaCHI can usefully complement a healthy lifestyle with sufficient hydration, exercise, and a balanced diet.
As a true aperitif, RenaCHI unfolds its full effect BEFORE the meal: The bitter substances stimulate saliva flow, gastric juices, and the entire metabolism. A well-functioning metabolism produces fewer waste products that your kidneys have to excrete, thus indirectly relieving them. Ideally, take it 10–15 minutes before the meal.
A bottle contains 500 ml. With the recommended daily dose of 15 ml, a bottle lasts for about 33 days – so just over a month with daily use.
RenaCHI is a traditional food and is very well tolerated when used as directed (15 ml daily). No intolerances are known. Please adhere to the recommended daily dose. If you have existing kidney diseases or are taking medication (especially diuretics or blood thinners), please consult your therapist beforehand.
RenaCHI is ideal for anyone looking to support their kidneys preventively – especially with insufficient fluid intake, unbalanced diet, for people over 50 years old (when kidney function declines), during physical exertion or sports (increased metabolic products), or as a conscious support for natural excretion and fluid balance. Also perfectly suited as a herbaceous-clear aperitif alternative to conventional schnapps.
Yes, RenaCHI is 100% vegan and free from sugar, artificial flavors, colorings, excipients, and additives. It contains only water, spelt distillate (17% alcohol by volume), the 4 kidney herbs, and vitamin C. Made in Germany, without genetic engineering and animal testing.
Take 15 ml daily (3 teaspoons or ¾ shot glass) about 10–15 minutes before a meal. You can let RenaCHI dissolve slowly in your mouth or dilute it with some water. This way, the bitter substances fully develop their effect and optimally prepare your metabolism and kidneys.
