Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Cleavers is a traditional 'lymphatic' and urinary herb. Its uses are based almost entirely on folk tradition rather than clinical research.
What is Cleavers?
Cleavers (Galium aparine) is a sticky climbing plant used in Western herbalism as a mild diuretic and 'lymphatic' tonic for skin and urinary complaints.
What Cleavers is commonly used for
In supplements, Cleavers is most often included for women's bladder & urinary health, skin & anti-aging support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Cleavers works
Cleavers is proposed to have mild diuretic and anti-inflammatory effects, but its mechanisms are not well studied scientifically.
What the evidence says
Here's an honest snapshot of what published research suggests about Cleavers — including where the evidence is limited.
- There is essentially no robust clinical evidence for cleavers; its uses rest on traditional herbal practice.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Cleavers rather than relying on marketing claims.
Typical dosage used in studies
Traditional use is as a fresh juice, tea or tincture; standardised dosing is not established. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Cleavers is generally considered low-risk in traditional amounts, but safety data are limited and it is best avoided in pregnancy and with diuretic medications without guidance. As with any supplement, it's sensible to introduce Cleavers on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Cleavers
Medication & safety check
Herbs interact with prescription medicines more often than people expect — affecting drug levels, bleeding, blood pressure, blood sugar or sedation — and Cleavers is no exception. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Cleavers is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Cleavers with your doctor or pharmacist first.
