^^ Yes.
Works very good with acetone.
I did it with mhrb tea resin from about 200g of bark powder from 3x acid cooks, evaporated down to a resin.
Mixed with caoh (calcium hydroxide, lime), and some water to make a paste. Let it fully dry over night, powdered, and pulled with acetone.
You can just fasa it from there, to get fumarates, base it again and pull with heptane to get white xtyals, or evap the acetone to get a full spectrum freebase oil. Dissolve that in near boiling hot heptane, and freeze-x in a shot glass.
IIRC, the first 50ml heptane pull from my oil, from 200g of bark, precipitated out ~750mg of white freebase crystals. CAme out to a total of ~ 2.5ish grams of white freebase, and ~ another gram of active tryptamine oil, probably n-oxide and some other stuff.
IT works very, very good.
Even if you just basify a resin from an evaporated tea, with caoh, or sodium carbonate and pull with hot heptane, then freeze-x.
For fumarates for pharma, just use dry acetone on a dried basified resin powder to pull, and fasa it.
Even worked good for some 4-aco-dmt hcl goo i had that got a bit too hydrated. Same tek, just ended up with a fumarate salt, thats a lot more stable, and much, much less hydroscobic.
Good yields, simple, easy, quick, and very efficient as far as how much solvents you are using.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
