Ginger: According to the book, Healing Foods by DK Publishing House, ginger protects and heals the gut, hastens the movement of food through the gastrointestinal tract, and reduces wind, bloating and cramps. It also awakens the taste buds, and gets digestive juices flowing. Ayurveda too suggests that ginger is an excellent herb to kindle agni, or digestive fire. Before each meal, chop or grate a little fresh ginger, add a few drops of lime juice and a pinch of salt, and chew it up.
Black Pepper: It is packed with a compound called piperine, which boosts digestion naturally and helps in better absorption of food. Black pepper also improves secretion of hydrochloric acid that further helps improve digestion.
Ajwain: Mix 1 teaspoon of cumin, 1 teaspoon of carom seeds and 1/2 teaspoon of ginger powder and add this mix to a glass of warm water. Drink this concoction daily to keep acidity and indigestion at bay because ajwain is packed with active enzymes that help in boosting digestion naturally and facilitate release of gastric juices.
Clove: The eugenol present in clove is very effective in healing gastric problems like indigestion and flatulence. You can prepare clove tea to reap its benefits. Clove-infused water is also a good option.
