Uva Ursi at a Glance
Arctostaphylos uva-ursi, bearberry or uva ursi, is a low evergreen shrub in the Ericaceae family. The leaves are the principal herbal part.
Traditional Use
Bearberry leaf has a long history in European and North American urinary formulas. It has been used for short-term urinary discomfort, but traditional use does not prove that it can safely treat a urinary tract infection.
Arbutin and Hydroquinone
The leaves contain arbutin, which can be metabolized to hydroquinone-related compounds. This chemistry explains both historical interest and the need for conservative duration and dosing.
Safety
Uva ursi is not a good choice for prolonged or routine daily use. Nausea and digestive irritation can occur, and high exposure raises toxicity concerns. Pregnancy and breastfeeding should be avoided. Children and people with significant kidney or liver disease should not use it without professional guidance.
Urinary Red Flags
Fever, flank pain, vomiting, pregnancy, blood in the urine, urinary retention or recurrent symptoms require medical evaluation. Untreated urinary infection can progress to the kidneys.
Folklore
Bearberry has a long history in Indigenous North American traditions and later herbal commerce; cultural uses vary by nation and region.
Bottom Line
Uva ursi is a short-term traditional urinary herb, not an everyday wellness tea. Its arbutin chemistry and safety limits deserve respect. For educational purposes only.
