Where in Metro Manila can I find almaciga sap? How do I extract it?

[piroxchan]

This is for my Investigatory Project in Biology. It is a year-long project, but I need the materials as early as now. If you can give me information on where in Metro Manila I can find the tree, that would also be helpful. I will also need to know how I can extract the sap. Thank you very much. ------

Before trying to extract the sap, find out if the tree is a protected specie listed by the DENR. I don't know where in MM you will find them but some hardware stores sell almaciga resin since it is often used to varnish. ------
