Ginger or turmeric?
Ginger and turmeric are two relatives from the same family (Zingiberaceae); in both, the part used is the underground stem (rhizome). They sit side by side in kitchens and on supplement shelves, but their evidence and risks differ.

Key differences
- Ginger’s strongest evidence is for nausea: the European Medicines Agency accepts its use for nausea from motion sickness. Turmeric’s evidence is weaker; there are a few small studies on knee osteoarthritis pain.
- Turmeric’s active compound, curcumin, is poorly absorbed; taking it with black pepper and fat increases absorption.
- Liver injury has been reported with high-dose turmeric capsules; with ginger, high doses mainly cause heartburn.
- Both need care in people on blood thinners and in people with gallstones.
Which one, when?
For nausea, ginger is the one with evidence. Turmeric is safe as a spice in food; high-dose capsules should not be taken without asking a doctor.
