Where is it oozing?  There is a phenomena whereby water is pushed out of
leaves by the pressure of the water in the soil.  It is harmless if that
is all it is. My alocasia does it all the time.  The drips are at the very
tip of the leaf. However, if the liquid is very sticky I would look for
scale under the leaves.  Why not just wash the plant in some soapy water
(regular dish detergent in warm water) and rinse with water just in case
it is an insect.  Maybe spider mites contribute to this phenomena.
