I picked papaya / pawpaw for a year, and the tree sap burns you for months, you bleed in your sleep when you sweat, you lose your body hair where it burned and it never regrows.
Fig sap, it's like glue, I burned my lips and tongue as an avid fig forager, the trick is to wait at least a day when you pick a fig not totally ripe, so it burns less
Nature doesn't mess about.
