What is FECO?
Full Extract Cannabis Oil (FECO) is a highly potent whole-plant cannabis concentrate created through clean solvent extraction using food-grade ethanol or CO2. FECO contains 50-80% cannabinoids and preserves the complete plant profile including all cannabinoids, terpenes, flavonoids, and other beneficial compounds. This comprehensive feco oil guide explains everything you need to know about full extract cannabis oil.
What is feco compared to other extracts? FECO stands apart because of its creation method using cleaner, food-safe solvents. This makes full extract cannabis oil particularly popular among health-conscious consumers. The food-grade ethanol extraction preserves delicate terpenes that give FECO its unique profile.
History and Origins of Full Extract Cannabis Oil
While Rick Simpson pioneered RSO extraction, full extract cannabis oil evolved as a response to demand for cleaner, safer extraction methods. The development of FECO coincided with advances in CO2 and ethanol extraction technology. Today, FECO represents a modern approach to full spectrum extraction that prioritizes purity and safety alongside potency.

How FECO is Made
The process of how to make feco begins with decarboxylated cannabis flower. Food-grade ethanol or supercritical CO2 is used as the solvent to extract cannabinoids, terpenes, and other plant compounds. The mixture is then filtered and the solvent is evaporated gently at low temperatures to preserve heat-sensitive terpenes. The result is a pure, full-spectrum oil with superior flavor and aroma compared to other extraction methods.
The cleanliness of how FECO is made distinguishes it from other methods. Food-grade ethanol leaves no toxic residues, and CO2 extraction is completely solvent-free. This makes full extract cannabis oil ideal for those prioritizing safety and purity.
Full Extract Cannabis Oil Benefits
Full extract cannabis oil benefits include comprehensive therapeutic effects from the complete plant profile. The entourage effect—where all cannabinoids and terpenes work together—creates superior results compared to isolated compounds. FECO benefits users seeking whole-plant medicine with preserved terpene profiles.
- • Full spectrum therapeutic benefits
- • Preserved terpene flavor and aroma
- • Customizable cannabinoid ratios
- • Clean, food-grade extraction
- • Entourage effect for enhanced outcomes
- • High bioavailability and absorption
FECO Dosage Guide & Chart
Understanding feco dosage is essential for safe, effective use. While FECO is potent, it's slightly less concentrated than RSO (50-80% vs 60-90%), allowing for more flexibility in dosing. The famous "Start Low, Go Slow" protocol still applies: begin with a rice grain-sized amount (approximately 15-20mg) three times daily.

Standard FECO Dosage Protocol
Week 1-4: 1/4 rice grain 3x daily (approximately 15-20mg)
Week 5-8: 1/2 rice grain 3x daily (approximately 30-40mg)
Week 9+: Full rice grain 3x daily (approximately 60-80mg)
Adjust based on your individual response and tolerance. FECO's flexibility allows for customized dosing.
How to Use FECO Syringe
The feco syringe format provides convenient, accurate dosing. Here's how to use FECO properly:
- Warm the syringe slightly in warm water if the oil is too thick
- Dispense a rice grain-sized amount onto your finger or directly under your tongue
- For better taste, mix with food or beverages (FECO has better flavor than RSO)
- Consume with meals or fats to enhance absorption
- Wait 2-4 hours to feel full effects before taking additional doses
- Keep detailed dosing records for consistency and adjustment

FECO and Drug Interactions
Users considering full extract cannabis oil should understand potential interactions with medications. Cannabis, particularly the full spectrum of compounds in FECO, can interact with numerous medications through cytochrome P450 enzyme inhibition. Medications metabolized by CYP3A4 or CYP2C9 (statins, blood thinners, immunosuppressants, benzodiazepines, and many others) may experience altered metabolism when combined with FECO.
This doesn't mean FECO and medications cannot be used together—many patients successfully combine them—but medical supervision is critical. Healthcare providers familiar with cannabis medicine can monitor drug levels, adjust dosages, and watch for adverse interactions. The full-spectrum nature of FECO means there are more potential interaction points than with isolated cannabinoids. Anyone taking prescription medications should discuss FECO use with their healthcare provider before starting, especially those on blood thinners, immunosuppressants, or medications with narrow therapeutic windows.
Conversely, cannabis often allows medication reduction in therapeutic cannabis programs. Many patients successfully reduce or eliminate medications for pain, anxiety, and sleep disorders when using FECO. The goal of medical cannabis use should be improving overall health—sometimes this means using cannabis alongside medications, other times it means replacing them. Individual response varies dramatically, making professional guidance invaluable.
