Uses.—The ripe fruit, so dark a purple in color that it seems black, is edible and very popular in the Philippines, though not considered choice. Some suppose it to be harmful, but it is in reality very easy of digestion.
The syrup of the fruit juice, and the decoction of the trunk bark are both very efficacious in the treatment of diarrhœa and dysentery.
