Evaluates a standardised combined extract of Curcuma longa rhizomes and Cannabis sativa leaves, which the authors describe as a traditional Thai topical remedy prepared in cottonseed oil. The extract was standardised by HPLC against curcuminoids, ar-turmerone and cannabidiol (35.47 mg/g), then tested for anti-inflammatory activity in macrophages, psoriasis-relevant activity in keratinocytes and skin deposition in porcine ear skin. The authors report anti-inflammatory activity and preferential skin deposition. The study itself is pharmacology.
