What is FECO? Full Extract Cannabis Oil Explained
Full Extract Cannabis Oil (FECO) is a concentrated, whole-plant cannabis extract closely related to RSO. Like RSO, FECO aims to preserve the complete range of cannabinoids and terpenes, but it is often made with different solvents and refined for a cleaner, more consistent final product.
How FECO differs from RSO
The main distinction is the extraction solvent. RSO is traditionally made with ethanol or isopropyl alcohol, while FECO is frequently produced using food-grade ethanol with additional purification steps. FECO is often marketed as a more refined, medical-grade version of full-spectrum oil.
Both are full-spectrum extracts and both can be extremely potent. In practice, the terms are sometimes used interchangeably, but FECO tends to emphasize precise cannabinoid ratios and consistency.
Why patients choose FECO
- Precise, lab-verified cannabinoid ratios (including balanced THC:CBD options)
- Clean extraction with thorough purification
- Full entourage effect from whole-plant compounds
- Available in a range of potencies and formulas
How to use FECO
FECO is used much like RSO. Start with a very small dose, take it sublingually or with food, and increase gradually. Because balanced THC:CBD formulas are common with FECO, some users find it easier to manage psychoactive effects.
