What is Rick Simpson Oil (RSO)?
Rick Simpson Oil (RSO) is a highly concentrated, full-spectrum cannabis extract named after Canadian medical cannabis activist Rick Simpson, who popularized its use in the early 2000s. RSO is known for its exceptionally high THC content (typically 60-90%) and whole-plant therapeutic benefits.

The Story of Rick Simpson Oil
In 2003, Rick Simpson, a Canadian engineer, created this concentrated cannabis oil to treat his own skin cancer after reading about the potential of cannabinoids in medical research. After experiencing positive results, he began sharing his extraction method and providing oil to others free of charge.
Simpson's advocacy brought global attention to full-spectrum cannabis extracts, and "RSO" became synonymous with high-potency, whole-plant cannabis oil. Today, RSO is one of the most sought-after cannabis products for those seeking maximum therapeutic benefits from the plant.

Understanding the extraction process behind Rick Simpson Oil
1. Cannabis Selection
High-quality, high-THC cannabis flower is selected. Indica strains are traditionally preferred for their sedating properties.
2. Solvent Extraction
The plant material is soaked in a solvent (traditionally isopropyl alcohol or ethanol) to strip cannabinoids and terpenes.
3. Evaporation & Concentration
The solvent is carefully evaporated, leaving behind a thick, dark oil rich in cannabinoids.
