Show full details & how to prepare it
Cranberries are small, sour, bright-red berries that grow on low vines in cool, boggy ground. Long before anyone understood why, people noticed that sipping the tart juice seemed to help keep bladder infections from returning. Modern study suggests the berry holds natural compounds that make it harder for certain bacteria to cling to the lining of the bladder, so they get flushed away more easily.
The key word is prevention. Cranberry is best thought of as a gentle daily habit for people who get urinary infections again and again — not as something that will clear an infection you already have. Once burning, urgency, and other symptoms arrive, that is a job for a doctor, because an untreated bladder infection can climb to the kidneys.
Choose your cranberry wisely. The pure, unsweetened juice is quite sharp, so it is often watered down; many supermarket "cranberry cocktails," though, are mostly added sugar and offer little real help. Plain juice, or a simple cranberry capsuleDried, powdered herb packed into a swallowable shell for a measured dose.

Ways to prepare it
⚖️ Cautions
- Cranberry may help **prevent** repeat urinary infections for some people, but it is **not a treatment** — a real infection still needs a doctor and usually antibiotics.
- Many store "cranberry cocktails" are mostly sugar; choose the unsweetened kind or dilute the pure juice with water.
- If you take **warfarin** or other blood thinners, check with your doctor first, since cranberry may add to their effect.
- Cranberry is fairly high in oxalate, so go easy if you are prone to **calcium-oxalate kidney stones**.
- Use only normal food amounts in pregnancy or breastfeeding unless your doctor agrees, and stop if it upsets your stomach.
