King Harvest Indica THC Full Extract Cannabis Oil (FECO) is a flower-only oil consisting of Indica THC. It is a flower-only full extract derived from cannabis strains such as Girl Scout Cookies, Cotton Candy, GrandDaddy Purple, and Purple Kush varieties.

FECO(ht) the cannabinoids are extracted from the raw material (cannabis flower) with 5 quick rinses of sub-zero ethanol and liquid nitrogen. This process extracts higher cannabinoids with less plant material resulting in a more transparent, higher viscosity, and higher potency oil, usually ranging from 700-800mg of THC/g. This product is best used for patients with a very high tolerance to THC, cancer treatment, extreme pain management, recreational use, and infusing into edibles.

Great for back pain

I need another back fusion, plus have pinched nerves that cause extreme pain to radiate down my leg into my toes and causes them to cramp up. The VA refuses to do anything with it and refuses to give me something for the pain. This THC FECO HT is great I don't need a lot and it stops the radiating pain!

Finally relief!

My arthritis was so bad that my doctor put me on meloxicam but unfortunately that messed with my stomach and I had to go off of it. Everything I seem to take for the arthritis was bad for my stomach until I found your product. Not only does it help relieve the pain and inflammation but it relaxes me and helps me sleep at night. Thank you for the work you do!

Back Pain Relief

Excellent Relief for back pain. Much better than taking prescribed opioids every day. Thank you!

The FECO works!

Relief from pain at last! I have severe back pain due to broken L4 vertebrae. After decades of walking, working, and everyday living I had surgery in 1999 with 2 plates, 4 screws, and 4 cages (all titanium) my lower back is fused from L4 – S1. My spinal cord is severely scarred from years of being “Pinched Off” by the horizontal break on the L4 vertebra and living with pain. Since then I have had a spinal cord electric stimulator implanted around the fusion and I now need a T2-T5 fusion as the discs are gone. My doctors quit the pain medication years ago with the Opioid addiction crisis only prescribing anti-inflammatory medication which has created another problem with my stomach lining so I have refused to take these types of medication not to mention they have no effect on the pain I am feeling and prescribing physical therapy(yeah right I’m already in pain and they want me to move around). Harvest King’s FECO’s was recommended to me and I had my doubts as I have tried other CBD oils which had no effect on subduing my pain. Boy, I am so thankful for the recommendation and that Harvest King’s FECO products work!! They are truly in a class above all others. Finally, a product that does what it says and delivers a healthier way to ingest a product that offers so much to my well-being. Bravo Harvest King Bravo!!

FECO helped with the pain

High, my name is Marti. I’m a 55-year-old female. I worked for 20 yrs as a scrub nurse in the operating room. Elbow deep in humans for a living. It was the greatest job ever. I learned so much every day. About science, life. I was severely humpback as was my Paternal Grandfather. . I had an auto accident & broke a vertebra and damaged my spinal cord. I had 12-hour corrective surgery to repair the injury and straighten my spine. I’ve been on disability since. I used to be on fentanyl patches, OxyContin soma, I couldn’t sleep still because of the pain. I was miserable. I just wanted to die. I got off ALL of that. Now I use Kings Harvest products. FECO. The HT is crystal clear as honey. Definitely quality products that achieve my pain management goals & help muscle spasms as well. My wife even likes that I giggle now occasionally. I truly think Kings Harvest has saved my life. I have hope. There is something else out there that works!! Laws have changed regulating opiates. The medical profession doesn’t care about people in pain because it will not kill you such as heart disease. Lawmakers have assumed everyone abuses pain medications I have other problems.. but I can’t go on forever. I’ll send my X-rays. Just know osteoporosis is real. I broke my pelvis lying in bed watching tv. Ladies, take your calcium!! With Love- Marti
