Comments

– Before the arrival of antibiotics, uva-ursi was widely used to cure urinary infections. A few decades later, it is still used for this indication, especially as a complement to classic therapies (for example, antibiotics).

Efficacy:
A special edition of the French journal Science & Vie on medicinal plants, published in July 2020, estimated that the effect of uva-ursi leaves in the treatment of urinary tract infections has not yet been demonstrated, due to the lack of published scientific studies , including clinical trials. For example, a British clinical trial published in 2019 was negative.

– For an efficient fight against urinary infections, uva-ursi should be ingested with a basic diet (non-acidic).

– The name, uva-de-bear or uva-ursi, also found in Greek and Latin in its scientific name  Arctostaphylos uva-ursi , comes naturally and simply from the fact that bears appreciate it.

– In North America, this plant was used by the Amerindians, due to its medicinal properties, they already used it against urinary infections.
