What are home remedies to urinary tract infection?

Fluids + void often: Drink lots of water and empty your bladder frequently. Cranberry juice can help, but, antibiotics are the best way to treat a urinary tract infection.

UTI: Once you have an actual infection - antibiotics are really the way to go. Hydrate well. Cranberries can help to prevent UTI's but not so much of a help with treating them.
