FECO vs RSO
FECO (Full Extract Cannabis Oil) and RSO (Rick Simpson Oil) are both concentrated forms of cannabis oil. Despite their similarities, there are clear distinctions between the two.
What is Full Extract Cannabis Oil?
Full Extract Cannabis Oil (FECO) is a highly concentrated, whole-plant extract. It is sometimes confused with RSO (Rick Simpson Oil). RSO and FECO may seem similar to the untrained eye but there is an important difference.
FECO is the preferred term used by the cannabis industry to describe this grain alcohol or ethanol-extracted cannabis concentrate. RSO is extracted using isopropyl alcohol which, when ingested, has a risk of converting to acetone in the liver increasing the risk of toxicity.
FECO is considered to be one of the most versatile medical cannabis treatment options because of its high potency. It provides the broadest available spectrums of cannabinoids and terpenes—the components responsible for cannabis’ medicinal properties—which boost each other’s effects by the entourage effect.
Unlike conventional cannabis oil, FECO is a very dark and thick oil that is often packaged in a syringe for accurate dosing. While it can be used topically—direct application to a sore or localized area—it is normally used orally for optimum results.

How is RSO Different from FECO?
Rick Simpson Oil (RSO) was first created and named by its creator, Rick Simpson, in the early 2000s for medicinal purposes. He began experimenting with cannabis oil extraction techniques and gained widespread attention after sharing his story and promoting the use of RSO as a treatment for various medical conditions, including cancer.
As the understanding of cannabis extraction techniques advanced, producers began utilizing new methods that aimed to create extracts with a broader spectrum of cannabinoids and terpenes, leading to the adoption of the term FECO to differentiate these extracts. FECO is used to describe cannabis oils that are extracted using various full-spectrum extraction methods which aim to preserve the full range of beneficial compounds found in the cannabis plant.
FECO and RSO Extraction Processes
While both FECO and RSO are types of cannabis oil extracts, the primary difference lies in their extraction methods. RSO typically follows a simpler, isopropyl alcohol-based extraction process pioneered by Rick Simpson. FECO often undergoes a more nuanced extraction process, which may involve different, safer solvents and a broader spectrum of plant components.
FECO and RSO are produced utilizing a solvent-based extraction method. RSO is frequently manufactured using naphtha or a similar petroleum-based solvent. On the other hand, FECO is typically made using ethanol or CO2. This leads to a broader spectrum of plant components. Moreover, a long soak period is frequently used in the extraction of RSO, which can lead to a less refined end product.
While the extraction procedure for FECO is comparable to that for RSO, the finished product is more potent and purified. This is because the solvent used for FECO is typically stronger, resulting in a higher cannabinoid concentration and cleaner oil.
FECO and RSO Cannabinoid and Terpene Profile
High quantities of THC and CBD are present in both FECO and RSO, however, the ratios of these cannabinoids might change depending on the formulation.
Due to its comprehensive extraction, FECO often contains a broader spectrum of cannabinoids and terpenes compared to RSO. The therapeutic benefits of FECO are attributed to the entourage effect, where the many cannabinoids, terpenes, and other compounds work together to enhance each other’s effects. This full-spectrum approach is believed to provide more comprehensive relief compared to isolated cannabinoids.
Due to the varying extraction processes, the cannabinoid and terpene profiles of FECO and RSO differ. FECO, with its comprehensive extraction, often contains a broader spectrum of cannabinoids and terpenes compared to RSO. The therapeutic benefits of FECO are attributed to the entourage effect, where the many cannabinoids, terpenes, and other compounds work together to enhance each other’s effects. This full-spectrum approach is believed to provide more comprehensive relief compared to isolated cannabinoids.
FECO often has higher THC concentrations and a cleaner oil than RSO, making it more potent and refined than the latter. RSO, on the other hand, has a stronger taste and aroma of cannabis and is often less refined and viscous. Depending on the precise formulation and dosage, both oils might be suggested for various conditions.
FECO and RSO Medicinal Uses
FECO comes in a variety of forms, including balanced formulations, high-THC formulations, and high-CBD formulations. Every formulation is suggested for a distinct condition and has a different set of medical advantages.
Rick Simpson Oil was initially promoted as a cancer treatment by Rick Simpson himself. On the other hand, due to FECO’s full spectrum of cannabinoids and terpenes, it has gained popularity. FECO boasts versatile therapeutic applications and caters to a wider range of health concerns including chronic pain, inflammation, epilepsy and seizures, anxiety and depression, post-traumatic stress disorder (PTSD), sleep disorders, multiple sclerosis (MS), neurodegenerative diseases, and more.
FECO can be ingested orally, applied topically, or inhaled, among other ways. According to the patient’s demands and tolerance, different dosages of FECO are advised. However it is normally advised to start with a low dose and progressively raise it over time.
