How it is classified

Herbal actions
Diuretic, Astringent, Antimicrobial. Energy: cooling.

How people take it

Typical tea is made from about 1 to 2 grams of dried leaf, up to three times a day. Use for no more than about one week for mild bladder symptoms, unless a doctor says otherwise.

Tea, capsule and tincture.

Where to get it

Grows as a low, mat-forming evergreen in sandy and rocky soils across northern North America, Europe and Asia. Leaves are wild-picked or farmed. Sold as dried leaves, tea, capsules and tinctures.

Be careful

Can cause nausea, and it may turn urine dark green or brown. Regulators in Europe limit use to about one week, partly because of its hydroquinone-related chemicals. Avoid in pregnancy, breastfeeding, children and people with kidney disease.

Avoid if: pregnancy; breastfeeding; kidney disease; children under 12.

The honest take

Uva ursi has a long history for bladder problems, but there is little modern human research. Its arbutin can break down to hydroquinone, which is why use is limited to about a week. A true urinary infection needs a doctor, not a tea.
