Additional Information
FECO, or Full Extract Cannabis Oil, represents a significant advancement in cannabis-based therapies. Unlike RSO, which was made using harsh solvents, FECO is extracted using food-grade ethanol, resulting in a cleaner and more medically preferred product. This method ensures that a broader spectrum of cannabinoids and terpenes are retained, providing a more comprehensive treatment option.
The high terpene content in FECO contributes to its efficacy and reduced side effects. Terpenes not only enhance the flavor but also play a crucial role in the therapeutic properties of cannabis. For instance, limonene is known for its anti-inflammatory effects, while pinene can improve cognitive function.
FECO is available in various forms, including suppositories and precise capsules, making it suitable for different patient needs and preferences. Suppositories offer high bioavailability and minimal psychoactive effects, making them ideal for patients who require symptom relief without the risk of intoxication. Capsules provide a convenient and discreet method of administration, ensuring that patients can manage their dosage accurately.
The medical community's preference for FECO stems from its superior quality and safety profile. Oncologists, neurologists, and hospice professionals have found that FECO offers better results with fewer adverse effects compared to traditional RSO. This makes it an attractive option for patients seeking effective medical cannabis treatments.
When it comes to dosing FECO, it's essential to start low and increase gradually. Most patients find that they can effectively manage their symptoms with a daily dosage of 50–300 mg. However, for oncology patients under supervised care, higher dosages of up to 500–1,000 mg/day may be necessary.
Storage of FECO is straightforward. Refrigeration in a syringe can extend its shelf life to 2–3 years. It's important to warm the FECO before use to ensure optimal absorption and efficacy.
Choosing a trusted brand is crucial when purchasing FECO. Some of the top brands in 2025 include Papa & Barkley, Care By Design, Mary's Medicinals, and Wana Optimals in the US, and Tilray Full Spectrum, Bedrocan, Aurora, and Little Green Pharma in Canada, EU, and AU. These brands ensure that their products are lab-tested and meet the highest quality standards.
The price of FECO can vary depending on the brand and form. Generally, FECO costs between $35–70 per gram, with medical bulk often priced at $20–30/g. This makes it a cost-effective option for patients seeking long-term treatment.
