How to Make RSO Oil at Home – Step-by-Step Rick Simpson Oil Recipe Guide

Making RSO oil (Rick Simpson Oil) at home is a topic many people search for when they want to understand how to make Rick Simpson Oil, how to make RSO oil at home, or find a DIY RSO recipe. This detailed educational guide explains the traditional process step by step.

What Is RSO Oil (Rick Simpson Oil)?

RSO oil, also known as Rick Simpson Oil, is a thick, dark, highly concentrated full-spectrum cannabis extract made from the whole plant. It contains a rich profile of cannabinoids (especially high THC levels), terpenes, and other natural compounds that work together through the entourage effect.

Many people search for how to make RSO, RSO extraction method, or make RSO at home because they want to learn the classic solvent-based technique popularized by Rick Simpson himself. The traditional method involves using solvents to extract cannabinoids, then evaporating the solvent to leave behind concentrated oil.

Materials Needed for the Traditional RSO Recipe

For a small batch (using about 1 ounce / 28 grams of cannabis), you will need:

• High-quality cannabis flower, trim, or shake (indica-dominant strains are traditional)
• Food-grade solvent: 99% isopropyl alcohol or Everclear (190-proof grain alcohol) — never use rubbing alcohol with additives
• Rice cooker (highly recommended for safe evaporation)
• Large glass bowls or mason jars
• Cheesecloth or fine strainer
• Wooden spoon or silicone spatula
• Coffee filters (for final straining)
• Fan for ventilation
• Thermometer (optional)
• Safety equipment: Gloves, safety glasses, and fire extinguisher

Safety First - Critical Precautions

Step-by-Step Guide: How to Make RSO Oil

Step 1: Decarboxylation (Activate the THC)

Grind your cannabis material coarsely. Spread it on a baking sheet and bake at 220–240°F (105–115°C) for 30–45 minutes. This converts THCA into active THC. Stir halfway through. Let it cool completely.

Note: Some people skip this and let the heat from evaporation do the work, but pre-decarb gives more consistent potency.

Step 2: Soak the Cannabis in Solvent

Place the decarbed cannabis in a large glass bowl. Pour enough chilled solvent (Everclear or isopropyl) to fully cover the material (about 1–2 inches above). Stir and mash gently for 3–5 minutes. The solvent will turn dark green/brown as it pulls out cannabinoids.

For a cleaner extract, do a quick second wash with fresh solvent.

Step 3: Strain the Mixture

Pour the liquid through cheesecloth or a fine strainer into another container. Squeeze the plant material firmly to extract as much liquid as possible. Filter again with coffee filters for clarity.

Step 4: Evaporate the Solvent (Rice Cooker Method)

Pour the filtered tincture into your rice cooker (fill no more than halfway). Set the rice cooker to "Cook" or "Warm" mode. Keep the lid off and place a fan nearby for ventilation.

The alcohol will slowly evaporate. This can take 4–8+ hours depending on batch size. Never leave it unattended.

As the liquid reduces, you can add more tincture if needed. Stir occasionally. When only thick oil remains and no more alcohol smell is present, it is nearly done. The final temperature should stay below 250°F (121°C) to avoid degrading cannabinoids.

Step 5: Final Purification and Storage

Pour the hot oil into a small glass container. Let it cool and thicken into a dark, sticky tar-like consistency. Some people do a final gentle heat on low to remove any remaining solvent.

Store in a syringe or airtight glass jar in a cool, dark place. Properly made RSO can last months.

Yield: From 1 ounce of cannabis, you may get 3–8 grams of RSO depending on potency and efficiency.

Common Mistakes to Avoid

• Using the wrong solvent (avoid anything not food-grade)
• Poor ventilation → fire or health risk
• Overheating the oil → degraded cannabinoids and harsh taste
• Not straining well → plant particles in final oil
• Incorrect dosing later (RSO is extremely potent)

Safe RSO Dosing Guide

If you ever have RSO, remember: start low and go slow. Begin with a dose the size of half a grain of rice (very tiny amount). Wait several hours before taking more. Effects can be strong and long-lasting.
