Uva ursi is a favorite herbal support for women in particular, in the prevention and treatment of urinary tract infections. And there is a good reason for this – in addition to its time-honored reputation, research has also demonstrated its powerful effect against infections and its ability to soothe inflammation.
The Background of Uva Ursi
The genus of bearberry is ‘arctostaphylos uva-ursi’, it is a bright red berried evergreen shrub that hugs the earth as a groundcover. It grows naturally all over the world including in the forests of North America, Europe, Siberia, and the Himalayas.
Interestingly, it gets its name from bears (uva ursi meaning ‘bear’s grape’), because apparently those big furry creatures are particularly fond of the fruit of the bearberry bush. If you’re not familiar with uva ursi you may have actually heard it called bearberry (but certainly not barberry), mountain cranberry, kinnikinnick, or sandberry.
Marco Polo supposedly first chronicled the benefits of uva ursi when he discovered that Chinese practitioners used it successfully for kidney and urinary tract health. Native Americans are also known for using the leaves as a headache remedy as well as for urinary health, as an incense, and as an ingredient in a smoking blend.
The Science Behind Uva Ursi
The most studied compounds of this herb are arbutin and hydroquinone, which have been shown to have antimicrobial properties that can fight certain infections. Another compound found in this herb, allantoin, is an important component of aloe vera and can therefore soothe skin just as well.
One of the biggest benefits of uva ursi is its truly amazing ability to fight off infections in the bladder and urinary tract. It’s been used for this purpose for centuries and is currently approved by the German Commission E for treating inflammation in the urinary tract. Although the number of studies is lacking on uva ursi and its ability to treat urinary tract infections (UTIs), it is believed that the compound arbutin is the power behind its ability to fight UTI infections. Arbutin is converted by bacteria in the urine into something called hydroquinone. This substance has antimicrobial and astringent properties. Uva ursi also helps calm inflammation and irritation in the mucous membranes of the bladder and urinary tract, easing symptoms of UTI as it happens.
As a mild diuretic, uva ursi also has benefits for flushing toxins from the kidneys. It naturally promotes urination and can help reduce the buildup of uric acid. This process may be helpful in the prevention of kidney stones. Studies have also shown that bearberry extracts have also demonstrated a powerful effect against bacteria like E. coli that can cause digestive problems.
How To Use Uva Ursi
Uva ursi leaf is available in several different forms but is most often taken as capsules or an extract. The dried herb can also be used to make teas and tinctures. Although it can be used safely in most circumstances, as with any supplement, it is a good idea to consult with a qualified herbal practitioner before launching into a new routine.
The Precautions
There is some question as to the safety of the long-term use of bearberry and taking a high dose may lead to stomach upset. Uva ursi is a powerful herb and is not recommended for children. Most herbalists also recommend it not be taken during pregnancy or when breastfeeding. Due to its diuretic properties people who have kidney or liver disease should avoid it or consult a doctor before using.
And finally, bladder and urinary tract infections can be very serious, and can cause complications without proper treatment. Be sure to see your doctor for recurring and severe symptoms.
