Hemp Extract
Hemp extract is made from hemp, varieties of Cannabis sativa low in THC. Depending on the plant part used, it can contain cannabidiol (CBD) and other cannabinoids.
Does CBD improve sleep?
A pilot trial assigned 30 adults with insomnia to 150 mg CBD nightly or placebo for two weeks. Most sleep outcomes, including insomnia severity, did not differ. Objective sleep efficiency and well-being favored CBD on some measures. The mixed findings warrant larger trials, not a promise that a hemp extract treats insomnia. 1
What about anxiety?
A review of 11 randomized trials found promising but often contradictory anxiety results. Doses and anxiety conditions varied substantially. CBD remains a research candidate; these findings do not identify a reliably effective retail hemp extract. 2
