What is uncertain
Read off the same rows as above. Nothing here is added that the entry does not itself record.
- Thin evidence: Menstrual / osteoarthritis pain (grade C).
- Caution with Anticoagulants (warfarin): Mild antiplatelet — additive bleeding risk at high doses.

The evidence in words
What it is
Ginger (Zingiber officinale) is a culinary rhizome standardized to gingerols/shogaols, best known for nausea.
How it works
Its gingerols act on serotonin (5-HT3) and gut motility pathways involved in nausea, with anti-inflammatory effects via prostaglandin modulation.
What the evidence shows
Grade B for nausea — pregnancy, motion, and post-operative — with meta-analytic support. It also modestly reduces menstrual and osteoarthritis pain and some inflammatory markers. Cheap, food-safe, and genuinely useful.
How to use it
1–1.5 g/day of ginger powder, split; fresh ginger or standardized extracts also work.
Safety & interactions
Very safe; mild antiplatelet action at high doses (additive with anticoagulants). warfarin — Mild antiplatelet — additive bleeding risk at high doses.
Bottom line
A legit anti-nausea remedy with bonus anti-inflammatory effects. 1–1.5 g/day; mind the mild blood-thinning at high doses.
How it is used
As the entry records it, from the studies it summarises. Not a recommendation for you — doses that suit a trial population may not suit you.
