A friend is 87 and has a UTI, and is on an antibiotic. Her daughter has her on 8 oz of cranberry juice as well. Monday night she had spinach for dinner, and the next morning developed a nose bleed, which she is subject to anyway. My thought was that, like with Coumadin users who avoid these foods because of their blood thinning effects, that perhaps the combination of the spinach and cranberry juice was too much for someone who develops nose bleeds rather easily. What are your thoughts?,
