text: First you grind the substance you want to extract. Then you add a solvent (like ethanol) which will dissolve the oils but which can be removed by distillation or extraction with a polar solvent (such as water).\n\nRather than filtering the extract, you might want to place the extractable powder (or mush) in a filter that you can hang into the solvent (like a one-use tea-filter or an old towel). You heat the solvent carefully (don't boil it off yet) and take care that the material you want to extract has constant supply of "fresh" solvent.\n\nNext you get rid of the solvent. Carefully - many solvent fumes are flamable. In case of ethanol, you might want to add nearly boiling water to the liquid resulting from your extraction. Some of the alcohol will mix with the water, another part will boil away, leaving droplets of the oil swimming on the water. A foam ladle oon might suffice to fish the oil droplets from the water surface.\n\n\nMake sure you use edible ethanol if you are after edible stuff or "aroma oils" (which often are low-boiling esters rather than fats).
