Melons are a nutritious food. The seeds of cantaloupe were used in China to moderate fevers and the digestive system. Elsewhere, seeds were ground into a powder and used to treat tuberculosis. Cantaloupes are particularly beneficial to people with heart disease, as they have large of amounts of an anticoagulant known as adenosine. They also have high levels of potassium, which benefits those with high blood pressure. Due to their high water content, all melons are considered diuretics.
