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

What Is RSO Oil (Rick Simpson Oil)?

RSO oil, also known as Rick Simpson Oil, is a highly concentrated, full-spectrum cannabis extract. It was popularized by Rick Simpson, who created a thick, dark, tar-like oil using simple solvent extraction. True RSO is rich in THC and other cannabinoids, making it very potent. The goal of the traditional method is to extract as many plant compounds as possible into a thick oil suitable for oral use.

Many people search for how to make RSO, how to make Rick Simpson Oil, or DIY RSO recipe because they want to understand the process or control ingredients. However, professional labs use closed-loop systems for safety and consistency — home methods are far riskier.

Why People Want to Learn How to Make RSO at Home

Some are curious about RSO extraction method, RSO solvent extraction, or the classic rice cooker method. Others want to use trim, shake, or leftover material. While learning is valuable, remember that homemade RSO is difficult to dose accurately and may contain residual solvents if not evaporated properly. Lab-tested RSO oil from a trusted shop eliminates these risks.

Materials Needed for Traditional RSO Recipe (Educational Overview)

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

• 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)
• Gloves, safety glasses, and fire extinguisher

Step-by-Step Guide: How to Make RSO Oil (Traditional Rice Cooker Method)

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.

Safety Tips When Learning How to Make RSO

• Use Everclear (food-grade ethanol) instead of isopropyl whenever possible — it is considered safer for consumption.
• Test for residual solvent: The final oil should have almost no alcohol smell or taste.
• Start with very small test batches.
• Have a fire extinguisher rated for chemical fires nearby.
• Never use open flames or electric coils that can spark.
• If you smell strong alcohol fumes, stop and ventilate immediately.

Making RSO is dangerous. Many experts strongly advise against home extraction due to fire hazards and potential for impure product. Professional closed-loop extraction is much safer.

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)

After Making RSO: Safe 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.
