Ginger (Zingiber officinale)

Nausea · Inflammation · Pain

Tier 1 — Strong Evidence

What it is

One of the most versatile natural remedies for nausea. A Cochrane review (Matthews 2015) and ACOG guidelines support ginger for pregnancy nausea at ~1 g/day. Evidence for chemotherapy-induced nausea is more mixed — some meta-analyses (Marx 2013, Crichton 2019) suggest modest benefit as an adjunct to standard antiemetics, others are null. Anti-inflammatory activity via COX/5-LOX inhibition. At doses above 4 g/day it may mildly increase bleeding risk — use caution if on blood thinners.
