How to Make Rick Simpson Oil (RSO)

You'll Need:

  • 1 Ounce of decarboxylated indica cannabis
  • 1 Tall mason jar
  • 1 Short wide mouth mason jar
  • Blender
  • Rice cooker or crockpot
  • Infrared thermometer
  • Table fan
  • Cheesecloth and rubber band
  • Everclear (place in freezer 1 hour before using)

Important Warnings:

Use extreme caution when heating everclear. Perform cooking steps near an open window or slider with a fan to ventilate. Proper airflow is critical.

How to Make Rick Simpson Oil (RSO):

  1. Grind cannabis into a shake consistency using a blender. Grind in batches to avoid clogging.
  2. Transfer ground cannabis into the tall mason jar. Use everclear to recover any remaining grinds from the blender.
  3. Cover cannabis with enough chilled everclear to saturate. Stir and mash with a spoon. Place jar in freezer 45min-several hours.
  4. Strain everclear mixture through a cheesecloth-lined wide mouth jar, squeezing out liquid.
  5. Set up rice cooker near a ventilating fan. Place mason jar in cooker and add water to cannabis level.
  6. Cook on rice setting, monitoring temperature. Do not exceed 240 degrees. Takes 2-3 hours.
  7. It's done when dark and syrupy.

Important Tips:

  • Make outdoors if possible, always use a fan. Everclear is flammable.
  • Only use everclear, not rubbing alcohol.
  • Don't exceed 240 degree water temperature.
  • Research proper dosing and treatment uses.
  • Be cautious when purchasing pre-made. Making it yourself is safest.
