9. May Treat Gallstones And Improve Digestion
Lemon zest or peel have been traditionally used in cooking as an appetizer or a good digestive. This could be credited to the high pectin content that relieves indigestion and constipation and also increases bile secretion. This makes lemon peel ideal for improving the digestive function.
Few types of research also suggest that d-limonene in lemon peel dissolve gallstones and dissolve cholesterol-containing gallstones. Lemon peel has the potential to be used as an alternative to surgery for treating gallstones, but medical supervision is necessary.
