Why it works for Weakened Immunity:
- Immunostimulatory activity in vitro. A detailed phytochemical analysis and cell-based work showed that aqueous infusions and fractions of G. aparine stimulate lymphocyte activity (lymphocyte blast transformation) and contain immunoactive polysaccharides, flavonoids and chlorogenic-type acids that can activate immune cells in vitro. MDPI
- Immuno-enhancing effects in animals. An in-vivo study in cyclophosphamide (chemically)-immunosuppressed mice found dose-dependent recovery of spleen weight, increased splenocyte proliferation and higher NK-cell activity after G. aparine extract, suggesting immune-enhancing effects in that animal model. MDPI
- Antioxidant & wound/antimicrobial actions that support immune function. G. aparine extracts show antioxidant (ROS-scavenging) activity and some antimicrobial/wound-healing effects in lab assays; those properties can indirectly help host defenses (e.g., by reducing oxidative tissue damage during infection and supporting local wound healing). MDPI Europe PMC
Summary on mechanism: compounds identified (polysaccharides, iridoids, flavonoids, phenolic acids) plausibly produce mild immunostimulation and antioxidant effects in cells/animals — this is the biochemical reason herbalists use cleavers for “lymphatic support” and low-grade immune support.

How to use for Weakened Immunity:
- Infusion / tea (most common):
- – How: Use fresh or dried aerial parts. Typical recipe: ~1–2 teaspoons (or 2–3 g) dried herb per cup (250 mL) of hot water; steep 10–15 minutes (or make a cold infusion overnight for a gentler “spring tonic”).
- – Usual intake: 1–3 cups per day for lymphatic/urinary/tonic use (herbal sources vary). PeaceHealth Handmade Apothecary
- Tincture / liquid extract:
- – How/ Dose examples: Common commercial tincture guidance: about 3–5 mL (≈½–1 tsp) up to three times daily, or follow product label / practitioner instructions. (Many dispensaries recommend ~60 drops 2–3×/day). NapiersSage Woman Herbs
- Fresh juice / spring tonic:
- – Herbalists sometimes juice fresh cleavers or make a 1:2 fresh-herb tincture; fresh preparations are considered more “nutritive.” Dosages vary widely—follow a practitioner’s guidance. You Are The Healer Handmade Apothecary
- Topical / poultice / compress:
- – Used traditionally for skin infections, wounds, swollen glands (as a compress or wash). For topical use, use preparations made for skin and patch-test first (see warnings). MDPI Europe PMC
Practical note: product concentrations vary — follow the label on commercial products or advice from a qualified herbal practitioner. PeaceHealth, Napiers and other clinical herb references give similar dosing ranges above. PeaceHealth Napiers
Scientific Evidence for Weakened Immunity:
The human clinical evidence is very limited. Most supportive literature is in vitro and animal experiments and phytochemical analyses:
- Molecules (2020) — Immunomodulatory Activity and Phytochemical Profile of Infusions from Cleavers Herb — in-vitro work showing lymphocyte stimulation and antioxidant activity from cleavers infusions and isolated fractions (polysaccharide, polyphenol, pectin fractions). This paper connects the phytochemicals to observed immuno/antioxidant effects. MDPI
- Nutrients (2024) — Immuno-Enhancing Effects of Galium aparine in Cyclophosphamide-induced Immunosuppressed Animal Models — an animal (mouse/rat) study showing dose-dependent improvements in splenocyte proliferation, NK-cell activity and cytokine changes after G. aparine extract. (Promising, but animal data.) MDPI
- Other in-vitro and preclinical reports / reviews — several studies report antioxidant, antimicrobial, hepatoprotective and anticancer cell-line activity of G. aparine extracts; there are a number of phytochemical and review papers summarizing these activities. Examples: ethanolic extract immunomodulatory profiles and phytochemical surveys. Semantic Scholar PDFs ScienceDirect
- What’s missing: I was not able to find well-powered randomized controlled trials (RCTs) in humans that demonstrate cleavers cures or measurably reverses clinically defined immunodeficiency. The evidence therefore supports biological plausibility and preclinical activity, but not clinical proof in humans. MDPI
Specific Warnings for Weakened Immunity:
Pregnancy & breastfeeding: safety is unclear — standard guidance is to avoid or consult a provider because there isn’t reliable safety information for pregnant or lactating people. WebMD RxList
Drug interactions / diuretic effect: cleavers has diuretic/alterative actions in folk use; people on diuretics, blood-pressure medications or some other drugs should be cautious and check with their clinician. Some sources also flag possible interactions with anticoagulants (not well documented) — again: check with a pharmacist/doctor. Statcareherbdictionary.org
Autoimmune / transplant / on immunosuppressants: because cleavers can stimulate immune function in lab/animal studies, avoid using immunostimulant herbs without medical advice if you have an autoimmune disease or are taking immunosuppressant drugs (or have a transplant). This is a standard precaution for any herb suspected to modulate the immune system. (See general immunosuppression guidance.) MDPI Cleveland Clinic
Allergic / skin sensitivity: fresh cleavers can cause skin irritation or urticaria in some people — patch-test topical preparations and stop if irritation occurs. crowconsultations.com herbdictionary.org
Quality & ID risks: if foraging, be certain of plant identification (misidentification risk) and avoid contaminated plants (pollutants, pesticides). Commercial products vary in concentration and quality; choose reputable, tested suppliers. Handmade Apothecary Verywell Health
Not a replacement for standard care: cleavers should not replace vaccines, prescribed immune therapies, or treatment for diagnosed immunodeficiency. If you have clinically weakened immunity (HIV, chemotherapy, congenital immunodeficiency, post-transplant, etc.), discuss any herb use with your treating specialist before starting it.

General Information (All Ailments)
What It Is
Cleavers, also known as Galium aparine, is a common herbaceous plant belonging to the Rubiaceae family. It’s native to Europe, North America, and parts of Asia and is often considered a weed due to its sticky, clinging nature — its stems and leaves are covered in tiny hooked hairs that adhere to other plants, animals, or clothing.
In herbal medicine, cleavers have been used for centuries as a natural diuretic, lymphatic tonic, and detoxifying herb. Traditionally, it’s consumed as a tea, tincture, or juice made from the fresh or dried aerial parts of the plant.
How It Works
Cleavers are believed to work primarily through their diuretic, anti-inflammatory, and lymphatic-stimulating properties.
- Diuretic Action: Cleavers increase urine output by stimulating kidney function. This helps the body flush out excess water, salts, and metabolic waste products. The diuretic effect is gentle, making it useful for mild water retention and urinary tract health.
- Lymphatic Support: One of the plant’s most valued functions is supporting the lymphatic system, which plays a key role in immunity and detoxification. Cleavers are thought to help stimulate lymphatic drainage, encouraging the removal of toxins and waste from tissues and supporting healthy immune responses.
- Anti-inflammatory and Skin Benefits: Cleavers contain bioactive compounds such as iridoid glycosides, flavonoids, and tannins. These contribute to its mild anti-inflammatory and soothing effects, particularly helpful for skin conditions like eczema, psoriasis, or acne when taken internally or applied topically as a wash or poultice.
- Blood and Organ Cleansing: Traditionally, cleavers have been used as a “spring tonic” — a gentle cleanser for the liver and kidneys, helping rejuvenate the body after winter. Its detoxifying effect is said to promote clearer skin and improved energy levels.
Why It’s Important
Cleavers are valued in natural health and herbal medicine for their role in detoxification, lymphatic health, and urinary system support.
- Supports the Lymphatic System: Helps prevent stagnation in lymph flow, which may reduce swelling in lymph nodes and promote immune resilience.
- Promotes Healthy Skin: By aiding toxin elimination through the kidneys and lymph, cleavers can indirectly improve skin clarity and reduce inflammatory skin eruptions.
- Gentle Detox Herb: Unlike harsher detox agents, cleavers offer a mild, sustainable way to support the body’s natural cleansing systems without overburdening organs.
- Urinary Tract Health: Regular use may help prevent or relieve minor urinary discomforts such as cystitis, bladder irritation, or kidney gravel.
In holistic and traditional herbal systems, cleavers are often used in combination with other herbs like nettle, dandelion, or burdock to enhance cleansing and fluid balance.
Considerations
While cleavers are generally considered safe and gentle, a few important points should be noted:
Allergies and Sensitivities:
- Individuals allergic to plants in the Rubiaceae family should avoid cleavers. Some people may experience mild skin irritation when handling the fresh plant due to its tiny hooks.
Dosage and Preparation:
- Tea: Typically 1–2 teaspoons of dried herb steeped in hot water for 10–15 minutes, up to three times daily.
- Tincture: About 2–4 mL of a 1:5 tincture (in 25% alcohol) up to three times daily.
- Always follow dosage guidance from a qualified herbalist or health practitioner.
Medical Conditions and Interactions:
- Those with kidney disease, heart disease, or on diuretic medications should use caution, as cleavers may enhance fluid loss and alter electrolyte balance. Pregnant or breastfeeding individuals should consult a healthcare provider before use.
Quality and Freshness:
- Cleavers lose potency quickly when dried for long periods. Fresh juice or recently dried preparations are preferred for maximum therapeutic effect.
