“This product has worked for me, when I was sure nothing could. I have a large mass of platinum coils behind my right eye, due to an arterial injury about 15 years ago. The foreign body has caused nerve oversensitivity, resulting in embarrassing facial ticks and eye movement restriction. The CBC oil twice a day has dramatically improved face and eye function in just one month. Thank you!“

According to Amplified Fragment Length Polymorphisms". Journal of Forensic Sciences. 51 (2): 371–375. doi:10.1111/j.1556-4029.2006.00061.x. PMID 16566773.
Cannabis sativa L. subsp. sativa var. sativa is the variety grown for industrial use in Europe, Canada, and elsewhere, while C. sativa subsp. indica generally has poor fiber quality and is primarily used for production of recreational and medicinal drugs. The major difference between the two types of plants is the appearance and the amount of THC secreted in a resinous mixture by epidermal hairs called glandular trichomes. Strains of Cannabis approved for industrial hemp production produce only minute amounts of this psychoactive drug, not enough for any physical or psychological effects. Typically, Hemp contains below 0.3% THC, while Cannabis grown for marijuana can contain anywhere from 6 or 7 % to 20% or even more.
Textile expert Elizabeth Wayland Barber summarizes the historical evidence that Cannabis sativa, "grew and was known in the Neolithic period all across the northern latitudes, from Europe (Germany, Switzerland, Austria, Romania, Ukraine) to East Asia (Tibet and China)," but, "textile use of Cannabis sativa does not surface for certain in the West until relatively late, namely the Iron Age." "I strongly suspect, however, that what catapulted hemp to sudden fame and fortune as a cultigen and caused it to spread rapidly westwards in the first millennium B.C. was the spread of the habit of pot-smoking from somewhere in south-central Asia, where the drug-bearing variety of the plant originally occurred. The linguistic evidence strongly supports this theory, both as to time and direction of spread and as to cause."
Regarding your comment on CBD and colitis or inflammatory bowel disease. Immune cells patrol the gut to ensure that harmful microbes hidden in the food we eat do not sneak into the body. Cells that are capable of triggering inflammation are balanced by cells that promote tolerance, protecting the body without damaging sensitive tissues. When the balance tilts too far toward inflammation, inflammatory bowel disease can result. Now, researchers have found that a kind of tolerance-promoting immune cell appears that carry a specific bacterium in guts called Lactobacillus reuteri that is the normal part of the gut microbiome, and tryptophan, part of a protein-rich diet, soothes the inflamed gut because it increases the development of a population of immune cells that promote tolerance. Further, the bacterium needs tryptophan — one of the building blocks of proteins — to trigger the cells’ appearance, and the more tryptophan in the diet to feed the gut bacterium, Lactobacillus reuteri, the more of these immune cells there are.
Although cannabis can be used to make marijuana, CBD itself is non-psychoactive—meaning that it doesn’t get you high the way smoking or eating cannabis-related products containing THC (the plant's psychoactive compound) can. Still, there’s a lot doctors don’t know about CBD and its effects on the body, and a lot consumers should understand before trying it.
