Active Compounds |
Bearberry leaves contain arbutin, a powerful
astringent that has antiseptic properties. The leaf is also rich in
tannins, useful for tanning leather. The glycoside arbutin is the
active ingredient in uva ursi. Arbutin is present in fairly high amounts
(up to 10%) in uva ursi. It has been shown to kill bacteria in the
urine. Before it can act, however, the sugar portion of the arbutin
and its attached small molecule (known as hydoquinone) must be broken
apart. The urine must be alkaline for this to happen. Hydroquinone
is a very powerful anti-microbial agent and is responsible for uva
ursi's ability to treat urinary tract infections. Arbutin has also
been shown to increase the anti-inflammatory effect of synthetic cortisone. |
History |
Folk healers have used bearberry leaves
to make a tea that is used an a tonic and as a diuretic in many parts
of the world. The Cheyenne Indians drank the tea for back sprains;
others have used it for venereal diseases. |

A low growing, trailing evergreen shrub, 4 to 6 inches high. The
bark is dark brown or somewhat reddish. The leaves are dark green,

of pinkish-white, waxy, urn shaped flowers appear in April-June.
The bright red berries ripen in Autumn and last through the winter.

Soak the leaves in alcohol or brandy, then add 1 tsp. soaked leaves
to 1 cup boiling water. Drink 2 to 3 cups a day, cold.
Tincture: Take 10 to 20 drops in water, 3 to 4 times a day.
For alcohol based tinctures, many people take 5 ml three times
per day.
Herbal extracts in capsules or tablets (containing 20% arbutin)
in an amount of 250-500 mg three times per day can also be taken.
Use of uva ursi should be limited to no more than 14 days. To ensure
alkaline urine, 6-8 grams of sodium bicarbonate (baking soda) mixed
in a glass of water can be drunk. Individuals with high blood pressure
should not take baking soda. Do not take it for more than 14 days.

Safety |
Excessive use of bearberry can lead to stomach distress, and prolonged
use can produce chronic poisoning.
Some people may experience mild nausea after taking uva ursi. Avoid
taking acidic agents such as vitamin C or fruit juice, while using
uva ursi. Do not take if you are pregnant or if you are lactating.
