DCM is not flammable, and distills at a very low safe temperature, but you should not breathe the vapors of it. Because you don’t want to breath any in, it's best to use a proper distillation setup.

DCM is hard to get in pure form OTC.

Another solvent which is very similar to DCM is MEK (Methyl Ethyl Ketone). You can use MEK mixed with naphtha or heptane to approximate the qualities of DCM. The exact ratio of MEK to naphtha or heptane is critical though, and I don’t know it off the top of my head.

A 40:60 mix of MEK:heptane is a good starting point (if using MEK and naphtha, a 50:50 mix is probably better). The toxins (most likely bufotenine N-oxide) are insoluble in this binary solvent mix but bufotenine is soluble in it. Once extracted, you can then boil off the MEK, and then let the heptane (or naphtha) cool down and evaporate, and bufotenine will crystallize out of the remaining heptane (or naphtha if that was used).

(EDIT: I'm talking about using MEK:heptane in place of DCM for an A/B extraction of Yopo/Vilca)
