I have done a crude LSA-extraction from MG seeds a few times. I used zippo fluid as a non-polar solvent (purified benzin would be a lot better and it's available from pharmacies, at least here). As a polar solvent, I used ethanol. Extraction made from 10 grams of crushed and ground up seeds gave me a fairly strong trip with practically no nausea of whatsoever. I personally tend to get very nausious when ingesting even six grams of ground up seeds, so there certainly was great improvement in that area.

The seeds were first soaked in the non-polar solvent for few hours, strained and left to dry completely. Then they were soaked in the polar solvent for three days (shaking occasionally), strained, the mush was discarded and the solvent evaporated under normal room temperature in darkness. The residue was scraped from the bottom and stored safe from light until ingestion.

The results from my experiments with extraction have been so promising, that I will surely use this method also in the future.
