RSO Original
The full plant, concentrated. NW Leaf Bowl Best RSO, 2023 and 2024.
RSO (Rick Simpson Oil) is a full-spectrum cannabis oil that keeps as much of the whole plant as possible. We make RSO Original by extracting with 200-proof organic food-grade alcohol, never CO2 or hydrocarbon solvents.
Alcohol is a polar solvent, so it carries more than cannabinoids out of the plant. Along with THC, CBD, CBG and CBN, RSO Original keeps the terpenes, plant fats, waxes and chlorophyll that more refined oils strip away. That is why it is dark, thick and earthy — and why we call it the full plant, concentrated.
Every batch is tested to our DOH+ standard by Confidence Analytics. See the lab results for every batch.
Four cannabinoid profiles
THC RSO Original
THC-dominant, with a broad range of minor cannabinoids. Our most potent RSO, best suited to experienced consumers. Available in oral syringes and capsules.
Premium CBD RSO Original
CBD-dominant, offered in several CBD:THC ratios so you can choose how much THC comes along. Check each product's label for its exact ratio.
CBG RSO Original
Dominant in CBG (cannabigerol), the cannabinoid often called the "mother cannabinoid" because the plant builds THC and CBD from it. Made from CBG-rich cultivars such as Stem Cell CBG and Milky Way CBG.
Premium CBN RSO Original
CBN (cannabinol) blended with the full spectrum of THC, CBD and minor cannabinoids from our RSO Original oil. A favorite for evening use.
Frequently asked questions
RSO stands for Rick Simpson Oil, named after the Canadian advocate who popularized whole-plant cannabis oil. It is also called FECO (full extract cannabis oil).
What does RSO stand for?
1
Distillate is refined until mostly a single cannabinoid remains. RSO keeps the rest of the plant: terpenes, fats, waxes and chlorophyll alongside a full range of cannabinoids. If you prefer a refined oil, see our Platinum Distillate.
How is RSO different from distillate?
2
Yes. Skagit Value RSO is made by washing the same plant material used for RSO Original a second time, and comes in the same four profiles.
Is there a lower-cost option?
