Cannabis Extraction by Solvents

1. Break the peaks into smaller parts to allow the solvent to penetrate on a larger surface by dissolving all resin glands in the solvent.

2. Dip the plant material into the solvent and mix for about 10 minutes or more.

3. Remove the plant material and leave the solvent to drain.

4. Put the remaining liquid in a rice saucepan (or bain-marie) to make the solvent evaporate (be very careful at this stage of the process).

5. The viscous extract obtained when the solvent is evaporated (which I call honey or amber) is the cleanest form of resin that can be obtained and contains all the active molecules of plant matter. This process also purifies cannabis from all impurities and bacteria and, given the prolonged exposure to heat, the extract is fairly safe to use as it is presented!

6. Dosage is probably the most important element to consider once oily extraction is done. This must be set for attempts starting from low initial doses and is therefore the most difficult part of the whole process but probably the most important and to do seriously if you want to get positive effects.

7. According to Rick Simpson, between 60 and 75 grams of final product is obtained, starting with half a pound of dried flowers and this amount is sufficient for a cycle of cures.

Butane extraction is slightly different because it is not a fluid under normal pressure but a gas extraction or more precisely with a supercritical fluid. This technique produces excellent quality honey and oily extracts with full flavor, but the result also depends on the type of butane used and how the extraction process was performed.
