Note of Interest: LEO-HB Technology has overcome this obstacle noted in this study:

“Although berberine has been researched for many years and received positive therapeutic feedback in an animal model of depression, there is poor bioavailability of oral or parenteral administration due to low absorption and intestinal first-pass effect, restricting its utilization in the treatment of depression (Fan et al., 2019). Therefore, it is necessary to overcome the problem of bioavailability and improve its therapeutic effects before it can be applied to clinical treatment.”

CBD Clinical Studies

CBD and Sleep and Anxiety:

1. Cannabidiol in Anxiety and Sleep: A Large Case Series

A 2019 study published in The Permanente Journal found that CBD improved sleep and anxiety in a small group of people with anxiety and sleep problems. The study involved 72 adults, and the participants experienced improved sleep scores within the first month of taking CBD:

  • Shannon, S., Lewis, N., Lee, H., & Hughes, S. (2019). Cannabidiol in Anxiety and Sleep: A Large Case Series. The Permanente Journal, 23, 18–041. doi: 10.7812/tpp/18-041

Link: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6326553/

2. Cannabidiol as a Potential Treatment for Anxiety Disorders

Preclinical evidence conclusively demonstrates CBD’s efficacy in reducing anxiety behaviors relevant to multiple disorders, including PTSD, GAD, PD, OCD, and SAD, with a notable lack of anxiogenic effects. CBD’s anxiolytic actions appear to depend upon CB1Rs and 5-HT1ARs in several brain regions; however, investigation of additional receptor actions may reveal further mechanisms. Human experimental findings support preclinical findings, and also suggest a lack of anxiogenic effects, minimal sedative effects, and an excellent safety profile.

3. Cannabidiol presents an inverted U-shaped dose-response curve in a simulated public speaking test

Results: Compared to placebo, pretreatment with 300 mg of CBD significantly reduced anxiety during the speech. No significant differences in VAMS scores were observed between groups receiving CBD 150 mg, 600 mg and placebo.

4. Cannabis, Cannabinoids, and Sleep: a Review of the Literature

A 2017 study published in Current Psychiatry Reports reviewed the existing research on CBD and sleep, and concluded that Preliminary research into cannabis and insomnia suggests that cannabidiol (CBD) may have therapeutic potential for the treatment of insomnia. In addition, the author noted CBD may hold promise for REM sleep behavior disorder and excessive daytime sleepiness, while nabilone may reduce nightmares associated with PTSD and may improve sleep among patients with chronic pain.

CBD and Pain Management:

There have been several human clinical studies investigating the potential pain-relieving effects of CBD. Here are a few examples:

1. A double-blind, randomized, placebo-controlled, parallel group study of THC/CBD spray in peripheral neuropathic pain treatment

2020 randomized, double-blind, placebo-controlled trial published in the Journal of Clinical Medicine found that a topical CBD formulation reduced pain and improved physical function in people with peripheral neuropathy, a type of nerve damage that can cause pain and numbness in the extremities.

2. Efficacy, Safety, and Regulation of Cannabidiol on Chronic Pain: A Systematic Review

A 2019 systematic review and meta-analysis published in the journal Frontiers in Neurology evaluated the efficacy of CBD for chronic pain management. The authors analyzed data from 11 randomized controlled trials and concluded that CBD may be effective for reducing chronic pain in adults.

3. A double-blind, randomized, placebo-controlled, parallel-group study of THC/CBD oromucosal spray in combination with the existing treatment regimen, in the relief of central neuropathic pain in patients with multiple sclerosis

A 2018 randomized, double-blind, placebo-controlled study published in the European Journal of Pain investigated the effects of CBD on chronic pain in people with multiple sclerosis. The study found that CBD reduced pain and improved sleep quality in the participants.

“the amount of maslinic acid in natural edible sources is low, and data about its pharmacokinetics, which we are currently assessing in our laboratory, show that the triterpene has a poor oral bioavailability. From this it would appear that dietary maslinic acid is not sufficient to reach effective concentrations in target organs, thus the compound should be supplied in pure form, i.e. as a nutraceutical.”
