ABSTRACT
Atopic dermatitis (AD) is a highly prevalent chronic skin disease. Anti-inflammatory and antipruritic emollients (emollients plus) with excellent cosmetic properties may alleviate AD-related symptoms and reduce the number of exacerbations. To screen for herbal extracts with potent anti-inflammatory and antioxidative potential in human skin cell cultures. Ginger extract and synthetic cannabidiol (CBD) were identified and combined in the cosmetic product BNO 3731, which was evaluated in a randomized clinical trial. Preclinical anti-inflammatory effects of ginger extract, synthetic CBD and a combination thereof were evaluated in human skin cell cultures by analysing nuclear factor κB activation, release of inflammatory cytokines and endocannabinoid production. Clinical BNO 3731 was studied in a clinical trial comprising 44 AD patients (adults and children) and compared to a benchmark product over a treatment duration of five days. Symptom severity was evaluated by objective and subjective dermatological assessments as well as physiological skin parameters. Itch intensity was assessed using a numerical rating scale (NRS-11). Preclinical Ginger extract and synthetic CBD exhibited potent anti-inflammatory and antioxidative effects in vitro which were associated with elevated concentrations of the endocannabinoid, anandamide. Clinical BNO 3731 significantly alleviated symptoms of AD and improved physiological skin parameters. Itch intensity decreased significantly by 55%, and in 75% of subjects, itch improved ≥2 points on the NRS-11 scale. No adverse events were reported. BNO 3731, containing a unique synergistic combination of ginger extract and synthetic CBD, is an effective and safe treatment option for dry and eczema-prone skin, providing rapid and substantial relief of pruritus.
