    Ginger

    Zingiber officinale

    TL;DR

    One of the best-evidenced natural anti-nausea agents — 1 g/day of powdered ginger rivals some medications for pregnancy and motion sickness. Also modestly helpful for osteoarthritis pain and dyspepsia. Safe, cheap, and fast-acting.

    Frequently Asked Questions

    Overview

    A culinary rhizome with some of the strongest evidence of any botanical for nausea — including pregnancy-related, motion, and chemotherapy-induced nausea — plus moderate evidence for osteoarthritis pain and digestive discomfort. Active compounds are gingerols and shogaols.

    How It Works

    Gingerols and shogaols accelerate gastric emptying, antagonize 5-HT3 (serotonin) receptors in the gut and chemoreceptor trigger zone (the same target as ondansetron), and inhibit COX-2 and lipoxygenase inflammatory pathways.

    Quick Facts

    • 1 g/day reduces pregnancy nausea comparably to vitamin B6
    • Take 30-60 minutes before travel for motion sickness
    • Mild COX-2 inhibition — complements (not replaces) NSAIDs
    • Safe in pregnancy at standard doses (up to 1 g/day)
    • Fresh, dried, and powdered forms all work; dosing differs

    Safety Information

    Potential Side Effects

    Mild heartburn or mouth irritation at higher doses. Very high doses (>4 g/day) may cause GI upset.

    Contraindications

    Use caution near surgery (mild antiplatelet effect) and with gallstones (stimulates bile release).

    Drug Interactions

    • Mild additive effect with anticoagulants/antiplatelets (warfarin, aspirin) — usually clinically insignificant at up to 1 g/day
    • May potentiate hypoglycemic medications

    Pregnancy & Breastfeeding

    Dosage Guidelines

    Dosage Used in Studies

    500-2000 mg

    Best Time to Take

    For nausea: 250-500 mg every 4-6 hours as needed, starting before triggers (e.g., 30 min before travel). For arthritis: consistent daily dosing with meals.

    Best Form

    Standardized powdered ginger root (capsules) for consistent dosing. Fresh root and tea work but dosing is less predictable. For nausea, divided doses across the day outperform a single dose.

    Bioavailability

    Gingerols are well absorbed but rapidly metabolized; divided dosing maintains steadier levels. Shogaols (higher in dried/heated ginger) are more potent anti-inflammatories.
