Blueberry may help prevent and treat UTIs by keeping bacteria from attaching to the lining of the urinary tract.
Blueberry contains similar constituents as cranberry, and might also prevent bacteria from attaching to the lining of the urinary bladder. However, studies have not yet been done to determine if blueberry can help prevent bladder infections.
Asparagus (Asparagus officinalis), birch (Betula spp.), couch grass (Agropyron repens), goldenrod (Solidago virgaurea),horsetail, Java tea (Orthosiphon stamineus), lovage (Levisticum officinale), parsley (Petroselinum crispum), spiny restharrow (Ononis spinosa), and nettle are approved in Germany as part of the therapy of people with UTIs. These herbs appear to work by increasing urinary volume and supposedly helping to flush bacteria out of the urinary tract.Juniper is used in a similar fashion by many doctors. Generally, these plants are taken as tea.
