Ginger Extract — Supplements

Bioactive gingerol-rich extract with antiemetic, anti-inflammatory, and digestive health properties.

Overview

Ginger (Zingiber officinale) extract contains bioactive compounds including gingerols, shogaols, and zingerone with well-documented antiemetic, anti-inflammatory, and prokinetic properties. The antiemetic mechanism involves 5-HT3 receptor antagonism in the GI tract. Cochrane reviews and meta-analyses support its efficacy for nausea and vomiting of pregnancy, chemotherapy-induced nausea, and motion sickness. Additional evidence supports anti-inflammatory effects comparable to NSAIDs for osteoarthritis and dysmenorrhea.
