Rafsanjan, Iran: The daily topical application of hemp seed oil improves osteoarthritic knee pain, according to placebo-controlled clinical trial data published in the journal Pain Management Nursing.
Iranian investigators assessed the efficacy of cold-pressed hemp seed oil versus either placebo or the NSAID diclofenac (aka Voltaren) in 90 patients with osteoarthritic knee pain and stiffness. Patients enrolled in the trial were between the ages of 45 and 70 years old. Study participants were assessed at baseline and again at four weeks and at eight weeks.
Researchers reported that the topical application of hemp seed oil provided therapeutic effects similar to those of diclofenac and superior to those of the placebo. Investigators reported that the oil was “safe and well tolerated.”
The study’s authors concluded: “This randomized controlled trial found that the daily application of topical hemp seed oil improved knee pain, physical function, and perceived knee stiffness. … Topical herbal compounds may have a role in the treatment of painful chronic conditions, such as knee OA [osteoarthritis], to reduce the systemic adverse effects of oral drugs.”
