About the fruit:
Pōpolo (solanum nigrum), is an erect herb that grows 1 to 3 feet high. It used to grow abundantly in lowlands. The small white flowers became hua pōpolo (black juicy berries). These are enjoyed when eaten directly from the plant. The berries are carefully picked when ripe, and rinsed with several changes of water. It may be made into a sauce and used as a topping on ice cream or pies.
For medicinal purposes, the young shoots and tender leaves are gathered and wrapped in ti leaf bundles, it is then lāwalu (broiled) over coals. It relieves congestion in the chest. Other times, the leaves were pounded and the juice was extracted. A little honey was then added to sweeten for easier intake. This mixture was used for severe chest congestion.
