To increase the body's ability to digest food and boost stomach function, one can stop drinking with meals, have a breakfast like a king, lunch like a queen, and tea like a pauper, and consume the juice of a lemon with a little boiling water before meals. Additionally, using a quarter teaspoon of cayenne pepper in water before meals can also help stimulate gastric glands and improve digestion. Bitter herbs like ginseng, dandelion, and St. Mary's thistle can also stimulate the release of digestive enzymes and improve liver and pancreatic function.
