Zingiber officinale does not affect gastric emptying rate. A randomised, placebo-controlled, crossover trial.

The effect of the powdered rhizome of Zingiber officinale (ginger root) on the gastric emptying rate was investigated. In a double-blind crossover trial, 16 healthy volunteers were randomly allocated to receive either 1 g of ginger or placebo. Gastric emptying was measured using the oral paracetamol absorption model. Ingestion of ginger did not effect gastric emptying. The antiemetic effect of ginger is not associated with an effect on gastric emptying. No adverse effects were noted.
