Ginger speeds metabolic rate, plus it inhibits nausea and vomiting often caused by morning sickness or motion sickness.
Ginger has antiemetic action, stimulates the flow of saliva and gastric juices, and increases intestinal peristalsis. It also has known antibacterial, antifungal, molluscacidal, nematocidal and antiplatelet effects.
Clinical studies support the use of ginger for nausea. Ginger acts directly on the gastrointestinal tract by increasing motility and promoting adsorption of toxins and acids.
Studies in Denmark, Italy, and elsewhere have revealed that ginger is an effective as Dramamine, or more so, in the prevention of motion sickness. Furthermore, ginger users have been found to experience fewer side effects, notably sleepiness.
