Uva Ursi

How does Uva Ursi work?

Uva ursi can reduce bacteria in the urine. It can also reduce swelling (inflammation), and have a drying (astringent) effect on the tissues.

Are there safety concerns?

Uva ursi seems safe for most adults when used short-term. It can cause nausea, vomiting, stomach discomfort, and a greenish-brown discoloration of the urine. High doses or long-term use can cause liver damage, breathing problems, convulsions, eye problems, and death.

Severe liver problems can occur if used in children. Avoid use in children.

Do not take uva ursi if:

• You are pregnant or breast-feeding.
• You have an eye condition known as "retinal thinning."
