Ginger is a powerful herb that has been used for centuries to calm the digestive tract and support the immune system.
The most frequent use of ginger is for symptoms of upset stomach, occasional acid reflux and heartburn, general nausea and vomiting. Several controlled studies have reported that ginger is effective as an antiemetic—meaning it alleviates nausea.
Ginger has also been recommended as an expectorant (clearing mucus and often used to relieve coughs) and it is traditionally used in teas or soups to treat colds or bronchitis. When mixed with hot or cold water, it can exhibit its anti-inflammatory properties as well and help soothe your coughing and general inflammation.
