Toxicity: The unripe fruit and sap have low levels of toxicity when eaten.
Uses: Often planted in windbreaks. Native Americans and pioneers ate the fruits raw or dried and used the berries to make juice and jam. The sun or fire dried fruits were preserved for winter use and used as food when hunting. An infusion of bark was used to treat dysentery and worms and an infusion of roots taken for urinary disorders. Mulberry sap was rubbed on ringworm and bows were made from the wood.
Comments: Mulberry is an understory tree. The wood is light, soft, coarse-grained, pale orange, and is very durable. It was used in the past to make fence posts. The leaves on the same tree may be entire or deeply lobed.
