What is Bearberry?
Common bearberry is a fruit that belongs to the genus Arctostaphylos uva-ursi. The word uva-ursi means ‘grape of the bear’ because bears are fond of this fruit. It is a low-growing shrub, which can be found in Asia, Europe, and Central and North America. Other names of this fruit are kinnikinnick, pinemat manzanita, crowberry, and beargrape. There are three different shrubs in all, the fruits of which claim the title of bearberry. The other two are Arctostaphylos alpine and Arctostaphylos rubra, commonly known as alpine bearberry and red bearberry respectively. Indigenous cultures have used the uva-ursi plant and its berries for traditional healing methods. The plant is unusual in that with its organic compounds and components that give it so many health benefits. There are also slightly narcotic elements as well, which is why the reputation and traditions of use of bearberries have changed and fluctuated over time. Now, you can mainly find bearberries in health food stores, herbalists, and those who still use folk medicine for treatments. The supplements of uva-ursi are also available in the form of herbal extract capsules.

Protects the Immune System
The most powerful chemical compounds, hydroquinones, found in bearberry, act as powerful antibacterial agents that can keep a wide range of diseases away from you. By eliminating harmful agents and foreign substances, bearberries can protect everything from your gut to your skin, acting as a defense against bacteria. 
Detoxifies the Body
Bearberry is most commonly used as a natural diuretic. Therefore, it helps eliminate excess salts, fats, water, and toxic materials from your body, simultaneously cleansing the bladder and kidneys. 
Bearberry has been used for hundreds of years as a headache reliever. To achieve this particular benefit, you need to smoke the dried leaves of the uva-ursi shrub, which produces a similar effect as the widely known cannabis plant. This narcotic use is one of the more controversial health benefits of bearberry and is looked down upon in many circles, but it is an effective headache remedy. 
Aids in Pregnancy
The active components of bearberry have been directly connected to prevent miscarriages, ensuring the safety of the mother during pregnancy. Furthermore, after the baby is delivered, there is often a significant amount of pain and inflammation. Eating bearberries has been used to promote a healthy recovery of the mother by eliminating some of the pain and discomfort.
Bearberry helps in reducing inflammation and therefore is very suitable for people suffering from rheumatism arthritis and the pain associated with it. 
Speeds up Healing

The acids of this unique fruit help speed the healing process under the skin, while also reducing inflammation and eliminating pain.
