What is Rick Simpson Cannabis Oil?

RSO is short for Rick Simpson Oil. Rick Simpson is the creator of this method of cannabis oil production. Rso, is made from the extracts of cannabis plant flowers.

The Cannabinoids are dissolved using isopropyl alcohol. Because the isopropyl alcohol only dissolves the cannabinoids, and not the plant matter, you can extract essentially, pure cannabinoids.

The alcohol is then filtered to remove large bits. Then you slowly heat up the alcohol until it is all evaporated. This leaves just the cannabinoids behind, and that is what we call Rick Simpson Oil.

  • 8oz of buds and tip leaf, with
  • 4L of Isopropyl alcohol.

The amount of oil you will need will depend on your dosage, and what you’re treating. For the correct dosing of cannabis oil medicines, you can ask for help in our cannabis growers forum

Step 1: Freeze your Buds

As isopropyl alcohol will not freeze until temps below −89 °C (−128 °F), it can be stored in a freezer at home. Along with your buds, put the Isopropyl alcohol into your freezer. This will make the trichomes brittle, and they will break off, and dissolve easily when you come to make your oil.

Step 2: Place Buds into Isopropyl

Once 24 hours has passed place your buds into a bucket. Break down the buds to smaller pieces to ensure the Isopropyl can get to more trichomes inside of them. The finer the better. You will filter this later so all the plant matter will be removed.


Place buds into Bucket over cover with Isopropyl Alcohol

When buds are sufficiently broken down, take 2L of the isopropyl alcohol out of the freezer. Now, pour it all over the buds, in the bucket. Leave the other half, you will use that soon.

Let this mix stand for around ten minutes. Stir constantly to dissolve as much of the cannabinoids as possible.

Step 3: Filter Out Plant Matter

Once stood, and the majority of the cannabinoids have dissolved, you have to removed the large pieces of plant matter.


Do this by fixing some cheese cloth over the top of a bowl. Then, slowly pour the mix onto the cheese cloth. The Isopropyl alcohol will run though, and be left in the bowl. All large piece of plant matter left on the cheese cloth.

Coffee filters can also be used in this part of the processes. But of course, you will have to use something smaller than a bowl to catch the solution after filtering.

To ensure you are extracting as much oil as possible, repeat step 2, and 3, one more time. Use the remaining 2 litres of isopropyl, and the remaining plant matter from your first rinse. Try to extract out as much as possible to increase your final yield.

Step 4: Heat The Isopropyl

This part can be dangerous!! Please be very careful! Do this part in A WELL VENTILATED AREA, AWAY FROM FLAMES AND SPARKS!!! It will explode if exposed to naked flames, don’t be the next news story in your area!

Using a rice cooker is most common, as this heats via an element slowly. No flames or sparks. This also gives us more control over the temperature.

Add your mix to the rice cooker, but do not exceed more than 3/4 full. Set your temperatures to 210–230 °F (99–110 °C).

If you have room in the pot for more as the solution evaporates, keep topping up the rice cooker. But do not exceed 3/4 full, to avoid spillages.

If the cannabis oil reaches over 300 °F (149 °C). It can burn and will be unusable. To prevent this from happening, add a few drop of water as the solution evaporates. The water will evaporate along with the isopropyl, but it will help keep the temperature down.

Step 5: Collect Your Cannabis Oil

After all of the Alcohol has evaporated, you will be left with a brown greasy substance. This is Rick simpson oil. Use syringes to suck up the oil. Place a cap on the end of the syringes to prevent spillage.


Use syringes to collect the oil

Your yield of oil will be between 10 and 25 % of the weight of plant matter you started with. This will depend on the initial THC and CBD content of the buds.

The amount of buds and alcohol may differ for you, but the process is the same. Just be careful when it comes to ventilation whilst evaporating the alcohol!

  1. Personally, I have never grown weed to produce CBD , I just prefer to use iSum ranked hemp CBD products that have zero THC. Actually CBD makes miracles. It has helped keep all the aches and pains in my joints in check and I have been able to double my workout levels at the gym
