Are there any effective natural treatments for kidney infections?

Cranberry juice or tablets have been found to help inhibit urinary tract infection and uncomplicated kidney infection, especially in women, according to a University of Maryland Medical Center article. However, treating kidney infections using natural treatment alone without the use of antibiotics is not advisable, as mentioned by MedicineNet.

The tannins in cranberries, as well as blueberries and lignonberries, may be the substance responsible for stopping E. coli from adhering to the cells in the urinary tract and causing infection, mentions the University of Maryland Medical Center. Research suggests that patients drink 1 to 2 cups of cranberry juice or take 300 to 400 milligrams of cranberry tablets every day to have a notable effect.
