What is Uva Ursi Extract 10:1 Used For? What is its Purpose?
What is Uva Ursi Extract 10:1 used for? Bearberry (Arctostaphylos) is a standardized herbal raw material traditionally used in dietary supplements for relief of lower urinary tract complaints due to its content of hydroquinone glycosides (especially arbutin). With its standardized 10:1 content, it provides a consistent source of ingredients in formulations such as capsules, dried leaves (tea), liquid/dry extracts, and tablets.
Benefits and Main Uses of Uva Ursi Extract 10:1
- Lower Urinary Tract Relief: Based on long-term traditional use, EMA/HPC states that bearberry leaf preparations can be used to relieve mild, recurrent lower urinary tract symptoms (burning during urination, frequent urination) (traditional use).
- Antiseptic and Urinary Tract Support: Arbutin and methyl arbutin are thought to exhibit antiseptic and anti-inflammatory effects when excreted in urine; they are traditionally used to support urinary tract flora (traditional use).
- Usage Limitation: EMA recommends use only in adult women and for periods not exceeding one week; definitive clinical evidence of efficacy is limited (limited evidence).
