I'm currently midway through my extract and my naphtha is evaporating from the seeds. The next step is soaking in alcohol and letting it evaporate. But I read that leaving the solution of LSA and alc out in open air will degrade the LSA. So would it be better to not evaporate it and just drink the tincture I pull? I'm not a big fan of alcohol as it upsets my stomach, and along with MGs I'm not sure how I'd feel. Anyone experienced both tincture and evaporated purer form? Any noticeable degradation?

Any degradation from evaporating off the alcohol is minimal. SWIM has done so with Isopropyl alcohol extract with a warm water bath and fan blowing to increase evaporation and everything turned out fine.

Plus after it is evaporated, you end up with a resin that can be redissolved in a small amount of acidified water, leaving behind impurities that can be filtered out. The main thing to NOT do is to leave the extracted ergolines dry and exposed to air, they will decompose pretty quickly over a week or two. Much more stable in solution refridgerated.
