cannabis oil inflammation

Cannabidiol (CBD) has been recently covered in the media, and you may have even seen it as an add-in booster to your post-workout smoothie or morning coffee. What exactly is CBD? Why is it suddenly so popular?

CBD is readily obtainable in most parts of the United States, though its exact legal status is in flux. All 50 states have laws legalizing CBD with varying degrees of restriction, and while the federal government still considers CBD in the same class as marijuana, it doesn’t habitually enforce against it. In December 2015, the FDA eased the regulatory requirements to allow researchers to conduct CBD trials. Currently, many people obtain CBD online without a medical cannabis license. The government’s position on CBD is confusing, and depends in part on whether the CBD comes from hemp or marijuana. The legality of CBD is expected to change, as there is currently bipartisan consensus in Congress to make the hemp crop legal which would, for all intents and purposes, make CBD difficult to prohibit.

How is cannabidiol different from marijuana?

CBD has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications. In numerous studies, CBD was able to reduce the number of seizures, and, in some cases, it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.

Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So, you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.

Research on CBD in animal models abounds and the cannabinoid seems to be able to interact with the immune system, reduce inflammation, and reduce pain from a number of conditions. Studies date back as far as 2009 but the most recent are highlighted here.

Research overview

“Inflammation is an extremely complex and varied process, and the effect of CBD and other cannabinoids is not completely understood at this time,” Riggle explained.

Amy Orr, author of the book “Taming Chronic Pain,” has been using CBD oil for three years to treat the inflammation and pain associated with irritable bowel disease, an autoimmune illness.

A 2016 study published in Clinical Hemorheology and Microcirculation investigated CBD as a treatment for early pancreatic inflammation in diabetic mice. Pancreatic inflammation can lead to diabetes due to an invasion of immune cells that destroy insulin-producing cells. The mice who received 10 weeks of treatment with CBD developed diabetes later than the mice that didn’t receive the treatment. CBD-treated mice also showed a significant reduction in immune-cell activity.

There is good reason to be a cautious shopper. CBD products are largely unregulated in the U.S. market. Independent testing has shown mislabeling and lack of quality control. The biggest issues are strength of CBD (significantly more or less than the label says), the presence of undeclared THC, and contamination with pesticides, metals and solvents.

What is CBD? CBD, short for cannabidiol, is an active compound found in the cannabis plant. CBD is not intoxicating but may cause some drowsiness. The CBD in most products is extracted from hemp, a variety of cannabis that has only traces (up to 0.3%) of THC, the active compound that gets people high.

CBD can also be absorbed directly into the bloodstream by holding liquid from a spray or tincture (a liquid dosed by a dropper) under the tongue (sublingual) for 60 to 120 seconds. The taste may not be pleasant. Effects may be felt within 15 to 45 minutes.

Kevin Boehnke, PhD, a researcher at the Chronic Pain and Fatigue Research Center at the University of Michigan, focuses on medical cannabis as an analgesic and opioid substitute in chronic pain.

Daniel Clauw, MD, a professor of anesthesiology, rheumatology and psychiatry at the University of Michigan and director of the Chronic Pain and Fatigue Research Center, leads research on arthritis pain and fibromyalgia, and the effects of cannabis, particularly CBD, in pain.

Taking the First Step

On the skin. Topical products, like lotions and balms, are applied to the skin over a painful joint. Whether these products deliver CBD below the skin is unknown. Topical products may also include common over-the-counter ingredients such as menthol, capsaicin or camphor, making it difficult to determine if a positive effect is due to the CBD or another ingredient.
