Benefits of Persimmon
Natural anti haemorrhoid
Persimmon is known to possess antihemorrhagic properties. No wonder it has been used in controlling excessive bleeding from wounds since time immemorial. A nonastringent persimmon, on the other hand, contains less tannin and can be eaten while it is crispy, as in apples. Astringency can be removed by treating the fruit with carbon dioxide or alcohol.
