Biochemically, ginger can stimulate the production of digestive juices, such as gastric acid and bile, which can increase the speed of digestion. However, excessive stimulation of these digestive juices can lead to heartburn, acid reflux, and other digestive problems. This is because excessive acid production can irritate the lining of the esophagus and cause discomfort.

In addition, ginger can also have a laxative effect and can stimulate peristalsis, the rhythmic contractions of the muscles in the intestines that move food through the digestive tract. Excessive stimulation of these muscles can lead to diarrhea, bloating, and other digestive problems.
