Cloves contain substances that may help to reduce gas in the stomach and increase gastric secretions. This can speed up slow digestion, which may reduce pressure and cramping. Cloves may also help to reduce nausea and vomiting.

A person with an upset stomach could try mixing 1 or 2 tsps of ground or powdered cloves with 1 tsp of honey once a day before bedtime. For nausea and heartburn, they could combine the cloves with 8 oz of boiling water instead to make a clove tea, which they should drink slowly once or twice daily.
