FECO vs RSO: Simple Guide to Choosing Your Cannabis Oil

Written & posted by Ingrid Ferris

You’ve probably heard people talk about cannabis extracts and wondered what all the fuss is about. Two terms keep coming up: FECO and RSO. These concentrated oils have gained attention for their potential to support general wellness, but figuring out the difference between feco vs rso can feel confusing. This guide breaks down what each extract is, how they’re made, and what you should consider when choosing between them.

Both FECO and RSO are concentrated cannabis extracts that preserve the plant’s natural compounds. They’re not your typical tincture or oil. These products pack a higher concentration of cannabinoids, terpenes, and other plant compounds into a smaller serving. That makes them popular among people who need stronger support for their wellness routines.

Defining FECO: Full Extract Cannabis Oil

FECO stands for Full Extract Cannabis Oil. The name tells you exactly what it is—an extract that uses the whole plant to capture all the beneficial compounds available.

When you look at FECO’s composition, you’ll find it contains 50% to 70% pure cannabinoids. The rest includes other plant compounds like terpenes, flavonoids, lipids, plant sugars, and chlorophyll. This full-spectrum approach means you get multiple cannabinoids working together—THC, CBD, CBG, CBC, and CBN all in one product.

The extraction process for FECO uses food-grade alcohol, typically ethanol, as a solvent. The cannabis compounds are extracted at low temperatures to preserve delicate plant materials. After extraction, the solvent is carefully purged and evaporated, leaving behind a dark resin extract.

FECO appears as a thick, dark oil with a consistency similar to tar. Most producers mix it with a carrier oil like olive oil or MCT oil to make it easier to use. At Myriam’s Hope Hemp, our Enhanced CBD FECO Oil uses a proprietary extraction system that removes harsh compounds while maintaining the full spectrum of beneficial plant materials. The result is a golden-colored oil rather than the typical black appearance.

People turn to FECO when standard tinctures don’t provide enough support. If you’re taking more than 200mg of CBD daily, FECO allows you to consume less oil per serving while still getting the concentration you need.

Defining RSO: Rick Simpson Oil

Rick Simpson Oil gets its name from Rick Simpson, a Canadian medical marijuana activist who developed this extract in the early 2000s. Simpson’s story began in 2003 when he was diagnosed with basal cell carcinoma. He applied cannabis oil directly to the affected skin areas, and within days, he noticed the spots had disappeared. This experience led him to advocate for cannabis and share his extraction method with others.

RSO is made using solvents like ethanol or isopropyl alcohol. The cannabis plant material soaks in the solvent, which dissolves the cannabinoids and terpenes. After the solvent evaporates, you’re left with a thick, dark oil that’s rich in cannabinoids.

Like FECO, RSO is a full-spectrum extract. It preserves the naturally occurring compounds in the plant, including cannabinoids, terpenes, flavonoids, and other phytochemicals. RSO often contains more than 60% THC, with some small-batch versions reaching concentrations as high as 80-90%.

The appearance of RSO is very dark and tar-like. It’s extremely thick and can be difficult to work with, which is why many people warm it slightly before use.

Understanding FECO vs RSO

When comparing feco vs rso, you’ll notice both are concentrated cannabis extracts that preserve the full spectrum of plant compounds. Both provide what’s called the “entourage effect”—where multiple compounds work together to create results greater than any single compound could achieve alone.

The main difference between feco vs rso comes down to the extraction solvent. FECO uses food-grade grain alcohol (ethanol), which is considered safer for human consumption. RSO traditionally uses isopropyl alcohol or naphtha, which are not food-grade solvents.

This solvent difference matters for safety. Food-grade alcohol used in FECO extraction is meticulously removed during the process, creating a cleaner product. Some RSO versions involve potentially hazardous solvents that aren’t safe for consumption if any residue remains.

Another distinction: FECO is typically produced in licensed, lab-grade environments with precise control over the extraction process. This allows for customizable CBD:THC ratios based on what you need. RSO was originally intended for specific wellness applications and tends to focus on high THC content. Many RSO formulas are homemade, which increases safety risks due to potential solvent residues and lack of lab testing.

Both oils appear dark, but FECO tends to be dark amber or green while RSO is very dark and tar-like. At Myriam’s Hope Hemp, our Enhanced FECO has a beautiful golden color because we remove the harsh compounds that typically cause the black appearance.

Extraction Methods and Purity

The extraction method determines the quality and safety of your cannabis oil. FECO extraction happens at low temperatures using food-grade alcohol. The process involves soaking cannabis flower in ethanol, filtering to remove plant solids, then slowly evaporating the alcohol using low heat. This gentle approach avoids damaging delicate compounds and concentrates the extract into a thick, sticky oil.

RSO extraction also uses solvents, but the type varies. While some producers use ethanol, others use isopropyl alcohol or naphtha. The extract is refined and the solvent is removed, leaving behind a thick substance. This process requires professional-grade equipment and should never be attempted at home—it’s extremely dangerous without proper training and materials.

Purity is where extraction methods really matter. Many people associate traditional FECO or RSO with a dark, almost black color. This appearance results from harsh chemicals used in the extraction process. These chemicals and the heat applied during extraction can create unwanted compounds in the oil.

At Myriam’s Hope Hemp, we use a proprietary extraction system that removes these harsh and potentially harmful compounds. Our Enhanced CBD FECO Oil maintains a wide range of cannabinoids, terpenes, flavonoids, and plant matter while eliminating the substances that cause safety concerns.

Lab testing for potency and purity is non-negotiable. Reputable manufacturers test for cannabinoid content, pesticides, heavy metals, and residual solvents. Our products are sourced from organically grown hemp and are free of pesticides, heavy metals, and other harmful substances. We make our lab results readily available so you can verify what you’re getting.

Potential Everyday Benefits

Both FECO and RSO support general wellness through their concentrated cannabinoid content. These full-spectrum extracts work with your body’s endocannabinoid system to promote balance and homeostasis.

Cannabis has been used as a natural method of relief for thousands of years. It can help reduce the body’s signals and help block certain responses. A 2020 review reports that CBD could have benefits for supporting overall comfort, improving sleep, and promoting calm.

The full-spectrum nature of these extracts means you get the entourage effect. Multiple compounds work together synergistically—cannabinoids, terpenes, and flavonoids all contributing to the overall experience. This is why many people find full-spectrum products more effective than isolated cannabinoids.

Our Enhanced CBD FECO Oil supports a sense of calm and focus. It aids in managing everyday tension and supports comfort after daily exertion. People who require higher potency CBD to achieve their desired effect often find FECO an excellent choice, especially if they’re taking more than 200mg of CBD daily.

FECO is often used for ongoing wellness support at a concentrated dose. The higher potency means a smaller amount may produce the effect you need, making it more economical for daily use.

Safety and Suggested Usage Tips

Starting with cannabis extracts requires a cautious approach. Even if you’re experienced with CBD or cannabis products, concentrated extracts are different.

For RSO, even users with high tolerance should start with a dose roughly the size of a grain of rice, or around 0.03 ml. Cannabis experts generally recommend a starting dose of 2.5-5mg THC for most products. With FECO, the same principle applies: start low and gradually increase to find your ideal dose.

Because of the higher potency inherent in FECO oil, a smaller amount may produce the effect you need. At Myriam’s Hope Hemp, we recommend starting low and increasing slowly. Our Enhanced CBD FECO Oil is best for experienced users or under healthcare guidance.

There are no official guidelines on safe or effective dosages for cannabis oils. Ideal dosages vary depending on type, form, and potency. Your body weight, age, and individual biochemistry all play a role in how you respond to these extracts.

Rick Simpson himself recommends a “titration method” for dosing RSO. This involves gradually increasing the dosage over several weeks. This gradual approach allows your body to acclimate and minimizes unwanted effects.

For administration, use the oral syringe to place a small amount under your tongue or mix it into food. Store your extract in a cool, dark place and follow the instructions included with your product.

Selecting the Right Option for You

Choosing between FECO and RSO depends on several factors. First, consider your experience level. If you’re new to cannabis extracts, FECO produced in a licensed facility with lab testing offers more predictability and safety. RSO, especially homemade versions, carries more risk due to potential solvent residues.

Think about the cannabinoid profile you need. If you’re looking for CBD-dominant options with minimal THC (less than 0.3%), FECO products like ours at Myriam’s Hope Hemp provide that balance. RSO traditionally contains high THC levels, which may not be legal or appropriate depending on your location and needs.

Extraction method matters. Food-grade ethanol extraction used in quality FECO products is safer than the isopropyl alcohol or naphtha sometimes used in RSO. If purity and safety are priorities, look for products that use food-grade solvents and provide lab testing results.

Consider your daily serving needs. If you require more than 200mg of CBD daily, a concentrated FECO allows you to consume less oil per serving. This makes it more practical for ongoing use.

Ease of use is another factor. Traditional RSO can be messy and difficult to measure accurately. Our Enhanced CBD FECO Oil comes in oral syringes that eliminate waste and make precise dosing simple.

Your wellness goals should guide your decision. Are you looking for ongoing daily support? FECO might be the better choice. Do you need professional guidance to determine the right approach? Consult with a healthcare provider or use the Leaf411 hotline at 844-LEAF411 (844-532-3411) and provide code MHCBD to waive your consultation fee before making your decision.

Budget also plays a role. While concentrated extracts cost more upfront, they last longer because you use smaller amounts per serving. Calculate the cost per milligram of cannabinoids to compare value accurately.

Final Thoughts on FECO vs RSO

The discussion around feco vs rso comes down to extraction methods, safety, and intended use. Both are concentrated cannabis extracts that preserve the full spectrum of plant compounds. Both offer the entourage effect that makes full-spectrum products effective.

The key differences lie in how they’re made and the resulting purity. FECO uses food-grade ethanol extraction in controlled environments, typically with lab testing to verify safety and potency. RSO traditionally uses harsher solvents and may lack the testing and quality control that ensures a safe product.

At Myriam’s Hope Hemp, we’ve refined the FECO extraction process to create a cleaner, more user-friendly product. Our Enhanced CBD FECO Oil removes harsh compounds while maintaining the beneficial cannabinoids, terpenes, and flavonoids that make full-spectrum extracts effective. The result is a golden oil that’s easier to use and backed by transparent lab testing.
