Comprehensive Guide: How To Make RSO Oil (Rick Simpson Oil) At Home

Rick Simpson Oil (RSO) is a highly concentrated, full-spectrum cannabis extract produced by macerating plant material in a high-proof solvent, filtering the solution, and evaporating the solvent under controlled heat. The resulting substance is a thick, tar-like oil that retains a broad profile of cannabinoids and terpenes, requiring extreme caution during the evaporation process due to the flammability of chemical solvents.

Pre-Operation Requirements and Safety Protocols

Producing RSO is a chemical extraction process that necessitates a strict adherence to safety standards. The primary risk involves the use of volatile solvents, which can ignite if exposed to open flames or improper electrical equipment. Before initiating the process, ensure your workspace is outdoors or in a laboratory-grade, well-ventilated area with a spark-proof exhaust system.

• Essential Gear and Materials:
  
  
  • One pound of high-quality, dried cannabis flower or trim.
  • One to two gallons of high-proof solvent (99% Isopropyl Alcohol or food-grade Ethanol).
  • Large stainless steel or glass mixing container (avoid plastic to prevent chemical leaching).
  • Fine mesh strainer or cheesecloth for filtration.
  • Coffee filters and funnel.
  • Rice cooker with a variable temperature setting (essential for controlled evaporation).
  • Silicone spatula for scraping.
  • Amber glass syringes for final storage.
• Mandatory Safety Standards:
  
  
  • Ensure all electrical appliances are explosion-proof or used strictly in a ventilated outdoor environment.
  • Keep a fire extinguisher (Class B for chemical fires) within immediate reach.
  • Use personal protective equipment (PPE), specifically nitrile gloves and safety goggles.
• Operational Benchmarks:
  
  
  • Estimated Time: 4 to 6 hours.
  • Yield Expectation: Approximately 50 to 60 grams of oil per pound of dried plant material (results vary based on potency).

Technical Extraction and Purification Workflow

Step 1: Material Preparation and Decarboxylation

To maximize the therapeutic efficacy of RSO, the raw cannabis material must be decarboxylated, which converts THCA into the active THC compound. Place your dried plant material on a baking sheet and heat it in an oven at 240 degrees Fahrenheit (115 degrees Celsius) for approximately 40 minutes. This process is non-negotiable for producing an orally active extract.

Step 2: Solvent Maceration

Place the decarboxylated plant material into your primary mixing container. Submerge the material completely with your chosen solvent. Use a wooden or stainless steel spoon to gently agitate the mixture for approximately three minutes. This movement helps the solvent strip the trichomes, cannabinoids, and terpenes from the plant matter.

Warning: Do not over-agitate or blend the material, as this pulls excess chlorophyll and plant waxes into the solution, resulting in a bitter, dark green oil of lower quality.

Step 3: Initial Filtration

Drain the solvent-cannabis mixture through a fine-mesh strainer or cheesecloth into a clean container. You will be left with the plant material, which still contains residual solvent and cannabinoids. Return the plant material to the mixing container, add a second wash of solvent, and agitate for another three minutes. Drain this second wash into the same collection container as the first. Discard the leftover plant matter.

Step 4: Final Polishing

Filter the combined liquid through a funnel lined with a standard coffee filter. This removes fine particulate matter, ensuring a cleaner final product. The solution should appear as a clear, amber-colored liquid at this stage.

Step 5: Solvent Evaporation

Transfer the filtered liquid into your rice cooker. Set the device to the low or warm setting. The goal is to evaporate the solvent without exceeding 300 degrees Fahrenheit, as excessive heat will degrade the cannabinoid profile. As the liquid levels drop, continue adding the remaining solution until all of it has been processed. When the liquid becomes thick and viscous, it is nearing completion.

Pro-Tip: Monitor the bubble formation. As the solvent disappears, the mixture will become thicker and slower to bubble. This is the indicator that the solvent is nearly gone. Remove from the heat source immediately once the bubbling slows to a crawl to prevent burning the extract.

Step 6: Final Collection

Once the evaporation is complete, use a silicone spatula to collect the thick, syrupy oil. Draw the oil into amber glass syringes while it is still warm and pliable. Allow the syringes to cool; the oil will set into a dark, solidified state at room temperature.

Technical Parameters of Solvent-Based Extraction

Post-Procedure Troubleshooting and Failure Analysis

• Failure Scenario: Residual Solvent Taste
  
  
  • Root Cause: Insufficient evaporation time or the rice cooker temperature was set too low, preventing complete phase transition of the solvent.
  • Actionable Fix: Return the oil to the heating vessel and apply gentle heat for an additional 30 minutes in a high-ventilation environment until the solvent aroma is entirely absent.
• Failure Scenario: Extremely Bitter or Grassy Flavor
  
  
  • Root Cause: Over-agitation of the plant material during the maceration phase, causing chlorophyll to leach into the solvent.
  • Actionable Fix: This cannot be reversed; in future batches, limit maceration time to strictly 3 minutes and handle the material gently without grinding.
• Failure Scenario: Oil is Too Hard or Brittle
  
  
  • Root Cause: Overheating the extract, which leads to the breakdown of terpenes and potentially further decarboxylation, hardening the wax profile.
  • Actionable Fix: Maintain stricter temperature control on the heat source; consider a double-boiler method if the rice cooker exceeds 250 degrees Fahrenheit.

Frequently Asked Questions

What is the ideal temperature for the evaporation process?

The ideal temperature for solvent evaporation is between 200 and 220 degrees Fahrenheit. Maintaining this range ensures the solvent reaches its boiling point while protecting the sensitive terpene profile and preventing the oil from burning.

How do I store finished RSO?

Finished RSO should be stored in amber glass syringes away from direct sunlight and heat. The dark glass prevents UV degradation, and keeping the oil in a cool, dry place ensures the cannabinoid potency remains stable for up to 12 months.

Can I use a regular stove for this process?

Using a regular kitchen stove is strictly prohibited due to the risk of ignition. The heating elements on conventional stoves are often exposed, providing an immediate ignition source for solvent vapors; always use an outdoor-rated, enclosed electric heating device.

How much RSO should be consumed per dose?

Standard protocols for RSO consumption begin with an amount the size of a half-grain of rice. Users should titrate their dosage upward slowly over several weeks based on individual tolerance levels and desired therapeutic outcomes.
