cannabidiol anti inflammatory

CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.

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.

Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.

The evidence for cannabidiol health benefits

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.

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.

CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.

Exposure of guinea pigs to LPS induced a 97 ± 7% and 98 ± 3% increase in neutrophils found in bronchoalveolar lavage fluid (BAL) at 4 h and 24 h, respectively. Administration of CBD and CBG formulated with MCT oil did not show any significant effects on the LPS-induced neutrophilia measured in the BAL fluid when compared with the vehicle-treated groups. Conversely, the administration of either cannabinoid formulated with CrEL induced a significant attenuation of the LPS induced recruitment of neutrophils into the lung following both intraperitoneal (IP) and oral (PO) administration routes, with a 55–65% and 50–55% decrease in neutrophil cell recruitment with the highest doses of CBD and CBG respectively. A combination of CBD and CBG (CBD:CBG = 1:1) formulated in CrEL and administered orally was also tested to determine possible interactions between the cannabinoids. However, a mixture of CBD and CBG did not show a significant change in LPS-induced neutrophilia. Surfactants, such as CrEL, improves the dissolution of lipophilic drugs in an aqueous medium by forming micelles and entrapping the drug molecules within them, consequently increasing the drug dissolution rate. Additionally, surfactants increase permeability and absorption by disrupting the structural organisation of the cellular lipid bilayer.

Our results suggest that the plant cannabinoids CBD and CBG have significant anti-inflammatory activity in the lung, but that formulation is critical to delivering an effective dose of these agents.


The second purpose of this study was to investigate the anti-inflammatory effects of cannabinoids formulated in two different formulations. The lipophilic nature of cannabinoids is a significant challenge for developing an effective formulation and bioavailability for optimal therapeutic effect [25]. Due to their lipophilicity, cannabinoids present negligible aqueous solubility. Additionally, they are vulnerable to degradation by auto-oxidation, light and temperature [26]. The first formulation tested in this study was composed of medium-chain triglycerides (MCT). They are lipids with a carbon chain length of 6–12 carbon atoms, making MCTs easier to absorb and metabolise than long-chain fatty acids (LCTs). Due to these characteristics, MCTs have been suggested as a drug vehicle for lipophilic drugs [27]. Our second formulation was a micellar solution composed of ethanol (EtOH), Cremophor® EL (polyoxyl 35 castor oil, CrEL) and sodium chloride 0.9% in purified water (saline). EtOH, a short-chain alcohol, is widely used as a solvent and co-surfactant for lipophilic drugs. CrEL is a non-ionic hydrophilic surfactant used to emulsify and solubilise lipophilic molecules by forming micelles and entrapping the lipophilic molecules within them in aqueous solutions. CrEL can also increase drug absorption by enhancing the dissolution rate of the drug by disrupting the lipid bilayer of cells [28]. Lastly, saline is a water-based solvent included in the formulation to obtain a final isotonic mixture.

In conclusion, this study has provided evidence that CBD and CBG formulated appropriately exhibit anti-inflammatory activity. Our observations suggest that these non-psychoactive cannabinoids may have beneficial effects in treating diseases characterised by airway inflammation.

Exposure to LPS (100 μg/ml; 20 min) resulted in a significant increase in total leukocytes in BAL fluid obtained 4 h ±30 min post-exposure (saline: 101 ± 7 × 10 4 vs LPS: 348 ± 115 × 10 4 leukocytes/ml, P < 0.001; Fig. 1 A; n = 4 for each group). A differential count of the leukocyte cells in the BAL indicated that neutrophils accounted for this increase in cell numbers (saline: 7 ± 7 × 10 4 vs LPS: 277 ± 83 × 10 4 neutrophils/ml (P < 0.0001, n = 4 per group) and represented 97 ± 7% of the total

Cannabidiol (CBD) is one of the main pharmacologically active phytocannabinoids of Cannabis sativa L. CBD is non-psychoactive but exerts a number of beneficial pharmacological effects, including anti-inflammatory and antioxidant properties. The chemistry and pharmacology of CBD, as well as various molecular targets, including cannabinoid receptors and other components of the endocannabinoid system with which it interacts, have been extensively studied. In addition, preclinical and clinical studies have contributed to our understanding of the therapeutic potential of CBD for many diseases, including diseases associated with oxidative stress. Here, we review the main biological effects of CBD, and its synthetic derivatives, focusing on the cellular, antioxidant, and anti-inflammatory properties of CBD.
