Because it is an entirely natural product, there is no evidence to suggest that taking more than the recommended dose of CBD oil can be harmful. However, LloydsPharmacy, which has recently begun stocking Celtic Wind CBD, advises this: "As with any food supplement, if you take more than the recommended dose you may feel unwell. We would strongly advise customers not to take more than the recommended dose and to consult their doctor if they have any concerns."
Epidemiological studies of various neuropsychiatric disorders indicate that a higher CBD content in chronically consumed cannabis may protect against adverse effects of THC, including psychotic symptoms, drug cravings, memory loss, and hippocampal gray matter loss [115–118] (reviewed in ). As THC acutely induces anxiety, this pattern may also be evident for chronic anxiety symptoms. Two studies were identified, including an uncontrolled retrospective study in civilian patients with PTSD patients , and a case study in a patient with severe sexual abuse-related PTSD , which showed that chronic cannabis use significantly reduces PTSD symptoms; however, these studies did not include data on the THC:CBD ratio. Thus, overall, no outcome data are currently available regarding the chronic effects of CBD in the treatment of anxiety symptoms, nor do any data exist regarding the potential protective effects of CBD on anxiety potentially induced by chronic THC use.
The results “suggest CBD to be a potential treatment for nicotine addiction,” the study authors wrote—but they also admit that their findings are preliminary. Ryan Vandrey, PhD, a cannabis researcher and associate professor of psychiatry at Johns Hopkins University (who was not involved in the 2013 study), agrees that larger, longer-term studies are needed to know if CBD might be helpful for smokers looking to kick the habit.
A 2012 research review assessed a number of international studies and concluded that CBD has been shown to reduce anxiety, and in particular social anxiety, in multiple studies and called for more clinical trials. Two years later, researchers in an animal study related to stress and the endocannabinoid system wrote that augmentation of the endocannabinoid system might be an effective strategy to mitigate behavioral and physical consequences of stress.
One of the most celebrated health benefits of CBD oil is its analgesic (pain relieving) effects. It’s thought that CBD interacts with receptors in the brain and immune system to reduce inflammation and alleviate pain. Some studies, such as this investigation published in the Journal of Experimental Medicine, found that CBD significantly reduces inflammation in mice and rats – but it’s not only rodents that experience these effects. A 2008 review identified that CBD offered effective pain relief without inducing adverse side effects in patients.
Have a high-stress job with an important pitch or presentation coming up? The fear of public speaking or intimidating social interactions is one of the most common forms of anxiety. For some, social anxiety simply makes parties, work gatherings, or a daily job uncomfortable and exhausting. For others with social anxiety, it is a crippling fear that keeps them locked indoors and in isolation.
Charlotte’s Web is the name of a premium CBD oil company, and the high-CBD strain of hemp from which their products are derived. The brothers who own and operate the company named it after Charlotte Figi, born in October 2006, who made an almost miraculous recovery from a rare and debilitating seizure disorder by using their CBD oil, and inspired them to found the business. Today, the Colorado-based company provides steeply discounted CBD oil to children with seizures and related disorders. Charlotte’s Web’s line of commercial CBD tinctures, capsules and topicals use the same proprietary strain of source hemp, but are formulated to address common issues like inflammation, fatigue, and anxiety. All are made from hemp grown organically and sustainable in Colorado, and subjected to broad-spectrum extraction, which maximizes the Entourage Effect (the capacity of hemp compounds to enhance the therapeutic effects of CBD) by preserving a range of beneficial plant compounds. Their CBD tincture is an excellent choice for treating anxiety, and comes in chocolate or chocolate mint flavors which can be taken directly or added to beverages. This CBD tincture is available in strengths of 10 or 25 mg per ounce, or a more concentrated 50 mg per 0.6 ounce. This oral supplement comes in natural or chocolate mint flavors. Charlotte’s Web’s CBD oil capsules contain the same full-spectrum CBD extracts, and come in concentrations of 15 mg each or 35 mg.
For the past couple of years, the field has been experiencing a boom in cannabidiol-related research. What has permeated the scientific consensus stems from efforts undertaken to explain effects of THC, with descriptions of cannabidiol just a by-product of the initial purpose. For example, CBD was thought to have been simply a precursor of THC, mainly due to the structural similarities between the two.
Zynerba is no longer pursuing a version of that drug for osteoarthritis, says Dr. Clauw, and there are currently no standard recommendations for what dosage or formulation of CBD (in either oral or topical form) might work best for pain relief. But he does want pain patients to know that CBD products may be worth a try—and that they may provide relief, even without the high that products with THC produce.
