FECO 3:1 – Full Extract Cannabis Oil
FECO 3:1 is a high-THC, full-spectrum cannabis oil blended with essential CBD for advanced-stage healing. Ideal for cancer, chronic pain, and autoimmune illness, this potent formula supports daytime function or nighttime relief depending on your blend.
Ratio: 3 Parts Indica THC : 1 Part CBD Type: Full Spectrum FECO (Indica or Sativa Blend Available) Best For: Advanced Cancer, Autoimmune Disorders, Chronic Pain
Originally developed for hospice patients managing end-stage pain, our 3:1 FECO has become King Harvest’s most trusted therapeutic oil. It is formulated with potent THC-dominant cannabis strains and infused with CBD-rich essential oil for immediate symptom relief and lasting biological support.

How It Works
This FECO blend combines multiple Indica-dominant THC strains with full-spectrum CBD oil, activating over 100 cannabinoids to engage the endocannabinoid system. The THC penetrates dense or advanced tissue while CBD reduces systemic inflammation, balances immune response, and supports overall recovery.
Strain Lineage
FECO 3:1 is a flower-only extract sourced from trusted medical strains including Girl Scout Cookies, Cotton Candy, GrandDaddy Purple, Purple Kush and related cultivars known for their powerful sedative and anti-tumor properties.
Functional Relief, 24/7
- Daytime: Sativa-dominant 3:1 for focus, mobility, and productivity
- Nighttime: Indica-dominant 3:1 for sleep, calm, appetite, and deeper pain relief
Patient Results
3:1 is our most commonly prescribed FECO for a reason: it works. Patients often report reduced tumor size, increased appetite, improved sleep, and significantly less pain—especially when other methods have failed.

Originally developed for severe pain and inflammation, High-Test FECO was created for patients seeking the absolute strongest THC content available—without the chlorophyll, waxes, or chemical residues common in traditional RSO.

By isolating the therapeutic compounds from cannabis flower, it offers consistent dosing and maximum absorption for patients who require aggressive cannabinoid intervention—often at 2–4 grams per day.
Flower-Only. Lab-Tested. Backed by Patient Care.
Made exclusively from premium cannabis flowers, High-Test FECO is third-party lab tested and completely solvent-free. Our care team supports each patient with a customized dosing strategy, ensuring comfort, efficacy, and long-term results.
