What Is Bearberry?
Bearberry, also known by its scientific name Arctostaphylos uva-ursi, is a small, hardy plant that grows in cold, rocky regions like the Arctic, northern forests, and mountain slopes. Often called “kinnikinnick” by Native American tribes, this low-spreading shrub is known for its leathery green leaves, delicate pink or white flowers, and bright red berries that attract wildlife, especially bears—which is how it got its name!
This tough little plant thrives in poor, sandy soil and harsh climates where other plants struggle. Its creeping stems form a dense ground cover, helping prevent erosion in fragile ecosystems. Beyond its role in nature, bearberry has a long history of traditional use. Indigenous peoples harvested its leaves to brew herbal teas, which were believed to support urinary and digestive health. Some tribes also mixed dried bearberry leaves with tobacco or other herbs for ceremonial smoking blends.
Today, bearberry is still used in natural remedies, particularly in teas and supplements, thanks to compounds like arbutin, which may have mild antiseptic properties. However, modern research hasn’t fully confirmed its medicinal benefits, and overuse can cause side effects like nausea or liver strain. Because of this, it’s important to use it carefully, especially for pregnant women or people with kidney issues.
Whether you spot it in the wild or come across it in an herbal remedy, bearberry is a fascinating plant with deep roots in history, ecology, and traditional wellness. Its ability to survive tough conditions—while supporting both wildlife and human cultures—makes it a true northern treasure.
How Does Bearberry Work?
Bearberry works through natural compounds in its leaves that may help support urinary tract health. The main active ingredient, arbutin, gets converted in your body into hydroquinone, which has mild antibacterial properties. When you consume bearberry as a tea or supplement, these compounds travel to your urinary system where they may help prevent bacteria from sticking to bladder walls. This could potentially ease discomfort from urinary tract infections, though it’s important to note that scientific evidence is limited and it shouldn’t replace medical treatment. The plant also contains tannins and flavonoids that provide antioxidant benefits, helping to reduce inflammation and protect cells from damage.
Some people use bearberry as a gentle diuretic to increase urine flow, which might help flush out bacteria, but this effect can also lead to dehydration if you don’t drink enough water. While traditional medicine has used bearberry for centuries, modern research hasn’t fully confirmed all its claimed benefits. It’s generally considered safe for short-term use, but taking too much or using it for extended periods may cause nausea, stomach upset, or other side effects. Pregnant women and people with kidney issues should avoid it unless approved by a doctor. The key with bearberry is moderation – it might offer some natural support for urinary health, but it works best when combined with proper hydration and medical advice when needed. Always check with a healthcare provider before using bearberry, especially if you’re already taking medications or have existing health conditions.
Bearberry works through natural compounds in its leaves that may offer health benefits, especially for the urinary system. The key ingredient is called arbutin, which your body converts into hydroquinone—a substance with mild antibacterial and anti-inflammatory effects. When you drink bearberry tea or take it as a supplement, arbutin travels to your kidneys and bladder, where it may help fight off bacteria and reduce irritation.

Bearberry – Benefits
1. Supports Urinary Tract Health
Bearberry is best known for its potential benefits for urinary health. The leaves contain a compound called arbutin, which converts to hydroquinone in the body. This may help fight bacteria in the urinary tract, potentially easing discomfort from UTIs. While it shouldn’t replace antibiotics for infections, many people use bearberry tea as a natural supplement alongside medical treatment. Its mild diuretic effect also helps flush out the urinary system, though you’ll need to drink plenty of water with it.
2. Provides Antioxidant Protection
This hardy little plant packs antioxidants like flavonoids and tannins that protect your cells from damage. These compounds help neutralize harmful free radicals in your body, which can contribute to aging and various health issues. The antioxidants in bearberry may be especially helpful for reducing inflammation in the urinary tract, but they benefit your whole body. Regular consumption (in moderation) might help strengthen your body’s natural defenses against oxidative stress.
3. May Support Skin Health
Bearberry extract has gained popularity in natural skincare products because of its arbutin content. This compound may help brighten skin and reduce dark spots by inhibiting melanin production. Some face creams and serums use bearberry as a gentler alternative to harsh skin lighteners. While results take time, it’s considered one of the more natural options for achieving more even skin tone without harsh chemicals.
4. Traditional Digestive Aid
Native American traditions used bearberry to soothe minor stomach discomfort. The tannins in the leaves have an astringent effect that may help with mild digestive issues. Some herbalists still recommend weak bearberry tea for occasional upset stomach, though it’s important not to overdo it. Too much can actually cause nausea, so this is one case where less is definitely more.
5. Helps with Water Retention
As a natural diuretic, bearberry can help reduce mild water retention and bloating. This makes it popular with some people looking for gentle fluid balance support. However, because it increases urine output, you need to be extra careful about staying hydrated. It’s not a solution for serious water retention issues, but may provide temporary relief for minor swelling.
