Had to dig this treasure of a topic back up.

OK, so you're in the forest...
You have a camp fire, pot, water and you boil your plant material. Grab some oranges as well, squeeze 1 in the brew to acidify it. Eat the rest and save the skins!!!!
While the brew is brewing go down the beach, grab some seashells. Crush them to a fine powder. This is going to be a fair amount of calcium carbonate. Throw the crushed seashells in the fire for a good amount of time. This will turn them to lime, and this is going to be your base.
And as long as this lengthy stuff is going is going on, grab those orange skins and distil them! One may need a kilo of orange peels to begin with, but what the hell, in the name of natural extraction this should not be a burden.
By distilling the orange peels you'll get a fair amount of d-limonene, a non-polar solvent that can be used to pull spice out.
Get the brew out of the fire and strain it. Grab the totally roasted crushed seashells, throw them in the brew. Solution gets basified. Now throw in the d-limonene, stir, stir stir and let the layers separate. Siphon off the limonene and evaporate it.
End result: Crude freebased smokeable spice ala forest!
Neat. Except camping in the forest & bringing a lab grade distiller isn't very
natural. So I guess this could be done by using a fairly low-tech distiller.
One like this, or something similair fashioned from a pot or kettle.
You may need to get creative with the cooling system & the pumping of the coolant,
but it should stay simple & natural.
The Orange peels may also contain some water, right? Perhaps the orange peels can be
grinded to shreds & covered in salt to pull out the water first? Assuming the salt
will not absorb any dlimonene, the dehydrated peels can then be further crushed &
thrown into the distiller. You will need some glass/pyrex beakers & flasks though.

Anyway if you want something a bit more green check out the non toxic limonene tek in this section of the forum. SWIMs imaginary friend observed that spice is very well soluble in d-limonene. The problem is evaporating the limonene at the end will be a messy goo.
If the season & climate zone permit it and there is frost, or if you're willing to be
a bit less natural & use liquid nitrogen or a freezer, then you could try to Freeze Precipitate the Spice out of the d-limonene.( If that is possible. Is it? )
Perhaps that would result in much cleaner Spice than the goo you described from
evaporating the dlimonene like SWIMs imaginary friend did?
And if you have this goo, from evaporating the dlimonene, then perhaps you could
wash away the impurities with cold water? Mix goo & cold water well & let it sit
for abt. 1 hour, then add dlimone, mix & wait and then siphon off the dlimone.
Evaporating this dlimonene might yield a purer product too, without doing anything
too unnatural.
