What is Rick Simpson Oil (RSO)?
Rick Simpson Oil is a concentrated, full-spectrum cannabis extract known for its high THC content and therapeutic potential. Developed by Rick Simpson in 2003, RSO has become one of the most sought-after cannabis extracts for wellness purposes.

What Makes RSO Special
RSO stands out from other cannabis extracts due to its unique properties and production method.
Full Spectrum Extract
Contains all cannabinoids, terpenes, and beneficial compounds from the cannabis plant.
High Potency
Concentrated formula with 60-90% THC for maximum therapeutic effect.
Entourage Effect
Multiple compounds working synergistically for enhanced benefits.
Long-Lasting
Effects can last 4-8 hours when taken orally or sublingually.
How is RSO Made?
Traditional RSO is made using a solvent-based extraction process. Cannabis flower is soaked in a solvent (often food-grade ethanol) to dissolve the cannabinoids, terpenes, and other beneficial compounds.
The solution is then filtered and the solvent is carefully evaporated using low heat, leaving behind a thick, dark oil that contains the full spectrum of cannabis compounds.
Our RSO undergoes additional purification and testing to ensure the highest quality and safety standards are met, while preserving the beneficial compounds that make RSO so effective.

How to Use RSO
RSO can be consumed in several ways, each with its own onset time and duration.
Oral Ingestion
PopularPlace on food or swallow directly. Effects take 1-2 hours to onset but last longest.
Sublingual
PopularHold under tongue for 60-90 seconds. Faster absorption than oral methods.
Topical Application
Apply directly to skin for localized relief. Does not produce psychoactive effects.
Suppository

Start Low, Go Slow
RSO is highly potent. Always start with a very small dose (grain of rice size) and wait at least 2 hours before taking more. Gradually increase your dose over time as you learn how RSO affects you.

What is the recommended dosage?
Start with a dose the size of a grain of rice (about 25mg). Wait 2-4 hours before taking more. Gradually increase over weeks as tolerance builds. The goal is to find your minimum effective dose.
Is RSO legal?
RSO legality depends on your location. It is legal in states/countries with medical or recreational cannabis programs. Always check your local laws before purchasing or using RSO.
