Rick Simpson Oil Recipe – Heal Yourself With RSO

Making your own RSO at home is not difficult, and the process isn’t all that different from making cannabutter or other kinds of infused cannabis oil. Rick Simpson recommends using indica cannabis strains for best results, although patients may prefer to use the cannabis strains that work best for their medical condition.

This recipe will produce the full 60 grams of oil for a 90-day treatment regimen.


  • 1 pound of dried cannabis material (indica strain)
  • 2 gallons of solvent – 99% isopropyl alcohol (can also use butane, ethanol, or other solvent)
  • 5-gallon bucket
  • A deep bowl
  • Wooden spoon for stirring
  • Cheesecloth
  • Coffee filters
  • Rice cooker
  • Coffee warmer
  • Plastic catheter tip syringe (60ml)

1. Place dry cannabis material into the 5-gallon bucket or in a bucket of good depth to prevent the oil solvent mix from splashing out during the washing process and pour in the solvent until the plant matter is covered.

2. Stir and crush the plant material with your wooden spoon while adding the solvent to your mixture. Continue stirring the mixture for about three minutes while the THC dissolves into the solvent. This will dissolve about 80% of the THC into the solvent.
Drain the solvent from the plant material into your bowl using the cheesecloth.

3. Place the plant material back in the bucket so it can be washed for the second time and add more fresh solvent and then work it for another three to four minutes, with the piece of wood you have been using.

4. Pour the solvent oil mix from the second wash, into the same container that is holding the solvent oil mix from the first wash you did.

Note: The first wash dissolves 75 to 80% of the available medicinal resins off the starting material; the second wash then removes most of whatever resin that is of benefit, which remains. Oils produced from the first wash are the most potent medicinally but if high-grade starting material is used, oil from the second wash also has strong medical benefits as well.

5. Pour the solvent oil mix from the first and second washes, into the coffee filters and allow the solvent oil mix to drain into the containers, which are holding the funnels and filters to remove any unwanted plant material The more funnels and containers you use, the faster the oil solvent mix will be filtered. Once the oil solvent mix has been filtered, it is now ready to have the solvent boiled off.

6. Transfer your solvent to your rice cooker until it is about ¾ full and turn on your rice cooker.

Note: While you don’t necessarily need a rice cooker, if you’ve never made RSO before, rice cookers are exceptionally useful in this instance for maintaining a slow, steady temperature. If your mixture heats above 300 degrees Fahrenheit (148 degrees Celsius), the cannabinoids will cook off and the RSO will be unusable. It is not recommended to use a Crockpot or slow cooker, as this may overheat your mixture. The rice cooker should maintain a steady temperature between 210 and 230 degrees Fahrenheit (100 to 110 degrees Celsius), which is the correct heat setting for decarboxylation to occur.

7. As the rice cooker heats up, the solvent will slowly evaporate. Continue to add your mixture to the rice cooker gradually.

Note: Make sure your rice cooker is in an open, well-ventilated area, and avoid all flames, stovetops, sparks, and cigarettes, as the solvent is highly combustible.

8. Once the solvent has evaporated, take the inner pot out of the cooker and pour its contents into a stainless steel measuring cup.

9. Take the oil that you poured into the stainless steel measuring cup and put it on a gentle heating device such as a coffee warmer to evaporate off whatever water remains in the oil.

10. When the oil on the coffee warmer has little or no bubbling activity visible, take the oil off the coffee warmer and allow it to cool a bit, after which it can be drawn up into the plastic syringes for use.
Another way to finish the oil without the use of a coffee warmer, is to put the oil in an oven set at 120°C or about(250°F) for about thirty minutes to an hour.

Note: As the oil comes down to room temperature, the resin or oil which contain the healing cannabinoids, will become a thick grease-like substance and it is then ready to use as a medicine. Sometimes the resin is so thick that it can be hard to force it out of the syringes when cooled. If such a thing happens, simply put the syringe in a cup of hot water, then in a short time you should be able to squeeze your dosage out more easily.

All you have to do is carefully follow these instructions and after you produce this medication a couple of times, you will find that it is not much harder to make than a cup of coffee.
