View photos of the medicinal plant Geum aleppicum (Avens), profiled in Medicinal Plants of the Western Mountain States.

A passage from Medicinal Plants of the Western Mountain States:

Use Avens as a soothing astringent for the urinary tract. If the urine is cloudy (denoting mucus) and/or strong smelling, both suggesting a possible infection, the tea is indicated. For extra disinfectant action combine Avens with Juniper, Thuja, or Cypress, otherwise the herb used alone should be fine for simple area irritability and/or mild infection.
