BASIC CANNABIS OIL EXTRACTION

[AusmedcannabisADMIN]

A Simple Extraction Method Using A Crock Pot or Rice Cooker

The better the quality of cannabis used, the better the resultant oil will be. Use top grade cannabis buds for the best results and completely dry the cannabis in an oven at 110ºC (230ºF). Usually takes about 30-45 mins. Depending on moisture content.

Place the bone dry cannabis material into a jar and cover with your solvent of choice, shake vigorously, the longer you agitate the mixture the more cannabinoids you will extract. However, if you use a polar solvent like Ethanol then short exposures are preferred as polar solvents also extract water solubles from the plant such as chlorophyll. Filter the plant solvent mixture, a coffee plunger or coffee filter work fine.



The filtration through a coffee filter will remove the empty trichomes and other fine contaminants. If you have filtered your solution correctly you will be left with an amber looking liquid.



Pour the liquid into a Rice Cooker or double boiler and with the lid removed, turn on. As the Rice Cooker heats up the solvent will start to boil. Be careful, boiling solvents are very volatile
ALL EVAPORATION SHOULD BE DONE OUTDOORS – NO NAKED FLAMES!



When the solvent has reduced in volume carefully pour into a good quality glass receptacle and complete the final evaporation on a hot plate or coffee warmer. As the volume reduces the mixture will be less volatile, Continue the evaporation process until there is no more activity.



The colour of the final oil will vary depending on the strain used, the method, the solvent used and of course the skill of the oil maker.

The oil is best stored in a syringe. Draw the oil up whilst slightly warm.
