[@Jangel13], that's most of it.  The javelins are poisoned.  I've also made a simple wooden short spear and used up the last of the numbing sap that I was carrying on the javelins.

I looked around for more numbing trees.  It's up to you whether any of them grow nearby, of course.

As a side note, I now have a Tree Camp! ... though I haven't figured out how to safely have a fire up there yet...
