Date palm
Sap

Apart from P. dactylifera, wild date palms such as Phoenix sylvestris and Phoenix reclinata, depending on the region, can be also tapped for sap.

The consumption of raw date palm sap is one of the means by which the deadly Nipah virus spreads from bats to humans. The virus can be inactivated by boiling the sap down to molasses. (In Malaysia, by contrast, the vector was found to be factory farming of pigs.)
