If you're looking to extract syrian rue, this is the Tek you are looking for. -

This will make your end spice, 100% food safe. Also if using d-limo, you can salt your spice out with fumaric acid and re-use your solvent. This will leave you with dmt-fumarate that will be a lot easier on your stomach for pharma journeys.
