Cranberry (Vaccinium macrocarpon)

Ericaceae · fruit

Cranberry

Vaccinium macrocarpon

Conflicting evidenceFood-like / generally well tolerated

Fruit mapped to conflicting prevention literature for recurrent UTI. Not cystitis treatment.

Safety first

Not a treatment for active UTI. Do not delay antibiotics when indicated. Cocktail juice is sugar. Concentrated tablets can interact with warfarin in some reports.

Tradition vs trials

Traditional record. North American fruit; later industrial juice and PAC extracts.

Trial literature. Prevention literature conflicts. Cochrane-type updates have gone back and forth. Treatment of acute UTI is not this mapping.

Practical ranges

Educational ranges — not a prescription. Culinary use is not an extract.

  • PAC extract

    Some prevention products aim for about 36 mg PAC (DMAC) daily — a convention, not a prescription

    NCCIH / Cochrane-era notesEducational range only — not a prescription. A licensed clinician individualizes product, dose, and duration.

Pregnancy, nursing, children

  • Pregnancy. Culinary juice is food-like; UTI in pregnancy is a clinician problem, not cranberry.
  • Nursing. Insufficient reliable data; avoid unless a clinician directs otherwise.
  • Children. Insufficient reliable data; avoid unless a clinician directs otherwise.

Contraindications

  • do not delay febrile/flank UTI care

Key interactions

  • warfarin · caution

    INR-change reports with concentrates; food juice is a weaker story.
