Uva Ursi, also known as bearberry, is a plant known for its therapeutic properties. Its leaves, which contain the active component arbutin, are widely used in traditional medicine to treat urinary tract infections and kidney infections and reduce inflammation. The supplement has shown promising antibacterial effects against a broad spectrum of bacteria, including Staphylococcus aureus.
The need to know
What are the benefits?
Reduces inflammation and poor gut health
Good for recurrent urinary tract infections (UTIs)
Natural herbal antibiotic
Uva Ursi's antimicrobial activity primarily comes from a compound called arbutin. Arbutin prevents bacteria from adhering to the tissues they target, a mechanism of action similar to procyanidins found in cranberries, widely used for urinary tract infections (UTIs).
Upon ingestion, arbutin is metabolized into hydroquinone, a compound that accumulates within bacterial cells, thus contributing to Uva Ursi's therapeutic effects. This antibacterial activity is essential for managing urinary tract infections and promoting urinary health.
In addition, arbutin has been used in skin care due to its ability to inhibit melanin production by blocking the enzyme tyrosinase. However, the effects are less pronounced when taken orally compared to topical application.
How will I know its working?
The effects of Uva Ursi might be noticeable in the relief of urinary tract infection symptoms, such as reduced discomfort and frequency of urination.
When to take it?
Take 1-2 capsules daily with food and water, unless specified otherwise on the sachet.
Do not take if you have renal disease. Not recommended if you are pregnant or nursing.

The name Uva Ursi, which means "bear's grape" in Latin, was given because bears are fond of the plant's berries.
Uva Ursi's antimicrobial properties have been recognised and used for centuries in various traditional medicinal systems.
The plant's leaves, the primary source of therapeutic compounds, are harvested in the summer and early autumn when arbutin content is at its highest.
