ImmuCHI: Your Immune Power Elixir for Natural Defenses, Gut Health & Well-being
Your immune system works tirelessly every day: It protects you from viruses, bacteria, and pollutants, often unnoticed but indispensable. The majority of your immune cells reside in the intestinal mucosa. However, stress, an unbalanced diet, and a lack of bitter substances challenge your immune system.
ImmuCHI brings back this forgotten power: Three carefully selected herbs – walnut shells, clove blossoms, and wormwood – combined in a spicy-warm bitter elixir. These plants have been valued in monastic medicine for their strengthening effect on the immune system. Through alcoholic-aqueous maceration, ImmuCHI preserves the full spectrum of plant substances and is enriched with antioxidant vitamin C.
While walnut shells are traditionally known for their supportive effect on the immune system, clove blossoms complement with powerful essential oils. Wormwood, the classic of bitter herbs, completes the formulation. Together, they create a harmonious bitter profile that naturally supports your defenses.
ImmuCHI supports you as a daily aperitif before meals: for strong defenses, a healthy gut, and natural well-being. Vegan, free from additives, and Made in Germany.
When ImmuCHI is particularly beneficial:
- When you want to naturally strengthen your defenses
- During the cold season or times of increased infection risk
- As support for your gut microbiome and gut health
- During stressful life phases that challenge the immune system
- For those who want to preventively support their immune function
- As a spicy alternative to conventional digestifs or schnapps
Why we developed ImmuCHI:
A strong immune system begins in the gut, and the gut begins in the mouth. ImmuCHI was created from the desire to harness the natural power of bitter substances for the immune system. The inspiration: monastic herbs like walnut, clove, and wormwood, known for centuries for their strengthening effects – as a spicy companion for strong defenses and conscious nutrition.

Many bitter herb products contain arbitrary herb mixtures or primarily alcohol. ImmuCHI is different: a targeted formula for the immune system and gut health – inspired by traditional monastic recipes.
This is what you should look for when buying a bitter herb aperitif:

How the Herbs in ImmuCHI Complement Each Other
Monastic Knowledge Meets Natural Synergy
Monastic medicine already recognized: A strong immune system needs targeted support, and nature provides special herbs for this purpose. ImmuCHI combines three of these traditionally valued immune herbs in a proven synergy: walnut shells, clove blossoms, and wormwood. 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:
- Walnut Shells (Juglandis nucum cortex)
The powerful protectors. Walnut shells are rich in tannins and have been valued in folk medicine for centuries—traditionally used to strengthen the body’s defenses and support the immune system. - Clove Blossoms (Caryophylli flores)
The spicy activators. Cloves provide powerful essential oils and bitter substances—known for their warming, strengthening effect. They add spice and depth to the recipe. - Wormwood (Absinthii herba)
The bitter classic. Wormwood is THE traditional bitter herb of monastic medicine—valued for its intense bitter power and its supportive effect on digestion and the immune system.
Ingredients:
Water, spelt distillate (approx. 17% Vol.), walnut shells (Juglandis nucum cortex), clove blossoms (Caryophylli flores), wormwood (Absinthii herba), ascorbic acid (Vitamin C)
Content:
500 ml Aperitif | 17 Vol. % Alcohol
Special Feature:
The alcoholic-aqueous extract in ImmuCHI concentrates both alcohol-, fat-, and water-soluble plant substances for a complete spectrum of effects from nature. Enriched with antioxidant Vitamin C for additional cell protection.

Your Aperitif Moment for Immune System, Defenses & Gut:
Take a moment daily and consume 15 ml of ImmuCHI (that’s 3 teaspoons or ¾ shot glass à 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 ImmuCHI 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
Why Your Immune System Needs More Support Today
Do you often feel more susceptible to colds during the cold season? It’s not just the weather. Your immune system works tirelessly every day: it fends off viruses, bacteria, and pollutants—often unnoticed but essential. However, modern lifestyles challenge it: stress, unbalanced diets, lack of sleep, and the absence of natural bitter substances keep your defenses running on low.
What many don’t know: The majority of your immune cells—about 70 to 80 percent—reside in the intestinal mucosa. A healthy gut microbiome is thus the foundation for strong defenses. Yet, even here, something crucial is often missing: bitter substances, which were once a natural part of our diet, have disappeared from almost all foods today.
The Forgotten Connection: Gut, Bitter Substances, and Immune System
Bitter substances are much more than flavor carriers. They activate receptors throughout the digestive tract, stimulate saliva and digestive juices, and promote a healthy gut environment—the basis for a functioning immune system. Even monastic medicine knew: certain herbs like walnut, clove, and wormwood not only support digestion but also the body’s defenses.
However, while conventional bitter herb products often contain arbitrary mixtures, ImmuCHI specifically focuses on three traditional immune herbs: walnut shells for their strengthening effect, clove blossoms with powerful essential oils, and wormwood as a classic bitter herb of monastic medicine.
The Solution: Targeted Immune Herbs as a Daily Aperitif
ImmuCHI combines these three plants in an alcoholic-aqueous maceration—a method that preserves both fat- and water-soluble plant compounds. The result: a complete spectrum of effects that simple powders or teas cannot offer. Enriched with antioxidant vitamin C, it creates a holistic aperitif for conscious eating culture and strong defenses.
The twist: ImmuCHI is enjoyed BEFORE the meal—not after. As a true aperitif, it prepares digestion, gut, and immune system optimally for the upcoming food. A small ritual with a big impact.
What Sets ImmuCHI Apart from Other Products:
ImmuCHI follows the orthomolecular approach of dr.reinwald vital: not 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 monastic recipes—but modernly interpreted for today’s needs.
Nutritionists recommend that people over 50 regularly consume bitter substances to support the natural production of digestive juices, which decreases with age. ImmuCHI makes it easy: 15 ml before the meal—a spicy companion for your defenses, gut health, and natural well-being.
FAQ & Frequently Asked Questions about ImmuCHI
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. ImmuCHI focuses on the immune system and intestines with walnut shells, clove blossoms, and wormwood. HepaCHI strengthens the liver and gallbladder (dandelion, milk thistle, artichoke), LympoCHI the lymphatic system (fir, olive, cranberry), and RenaCHI the kidneys (goldenrod, bearberry, horsetail). 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 in a rotation principle: for example, Monday to Wednesday ImmuCHI (immune system), Thursday to Saturday HepaCHI (liver), Sunday RenaCHI (kidneys). This way, you support different areas of your body. Pay attention to the respective daily dose of 15 ml per aperitif.
HerbiGOLD is a general bitter herb aperitif with 14 herbs for digestion, liver, and metabolism – ideal for daily culinary culture and as an “all-rounder.” ImmuCHI, on the other hand, is a targeted organ aperitif with 3 specific immune herbs (walnut, clove, wormwood) – perfect if you want to specifically support your immune system and gut health. HerbiGOLD = broad, ImmuCHI = specific for immune defenses.
These three herbs were already valued in monastic medicine for their strengthening effect on the immune system. Walnut shells are rich in tannins and traditionally known for their supportive effect on the body’s defenses. Clove blossoms provide powerful essential oils with a warming effect. Wormwood is a classic bitter herb that has been used for digestion and the immune system for centuries. Together, they form a harmonious synergy for your natural defenses.
As a true aperitif, ImmuCHI unleashes its full effect BEFORE the meal: The bitter substances stimulate saliva flow, gastric juices, and digestive forces – thus optimally preparing your intestines as well. Since the majority of your immune cells are located in the intestinal mucosa, good digestion is the foundation for strong defenses. Ideally, consume 10–15 minutes before the meal.
A bottle contains 500 ml. With the recommended daily dose of 15 ml, one bottle lasts for about 33 days – so just over a month with daily use.
ImmuCHI 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 illnesses, a weakened immune system, or are taking medication, please consult your therapist beforehand.
ImmuCHI is ideal for anyone looking to boost their immune system naturally especially during the cold season, in stressful life phases, for people over 50 (when the immune system weakens), or as a conscious support for gut health and immune function. Also perfectly suited as a spicy aperitif alternative to traditional schnapps.
Yes, ImmuCHI is 100% vegan and free from sugar, artificial flavors, colorings, excipients, and additives. It contains only water, spelt distillate (17% alcohol by volume), the 3 immune 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 ImmuCHI dissolve slowly in your mouth or dilute it with some water. This way, the bitter substances fully develop their effect and optimally prepare your immune system and digestion.
Yes, ImmuCHI can be easily combined with other dietary supplements including other products from dr.reinwald vital or the other CHI aperitifs. If you are taking medication, please consult your therapist beforehand.
