It is best not to eat persimmons on an empty stomach. Persimmon contains a lot of persimmon gum, which will solidify into blocks when it meets acid. When eating a large number of persimmons on an empty stomach, the persimmon gum in persimmons will condense with gastric acid into blocks, as small as apricot stones and as big as fists, which cannot be discharged if accumulated. Therefore, persimmon should not be eaten more at a time, but after meals, because gastric acid has been mixed with food at this time, and it is not easy to produce "persimmon stone".
