Don't drink the sap

Unripe #mulberries and the white sap from any part of the #mulberry plant can be mildly toxic. Eating large amounts of the sap can cause nervous system stimulation, hallucinations, indigestion, and nausea. The sap can also irritate the skin.

Infants and young children who eat the whole mulberry fruit may experience an acute sickness characterized by vomiting.
