In Vitro and Randomized, Double‐Blind, Placebo‐Controlled Trial to Determine the Efficacy and Safety of Nine Antiacne Medicinal Plants

Radioactive acetate incorporation into total lipids as a function of Cappris spinose (CS), Eruca sativa (ES), Ferula hermonis (FH), Hypericum triquetrifolium (HT), Inula helenium (IH), Linum pubescens (LP), Nigella sativa (NS), Saponaria officinalis (SO), Urtica dioica (UD), and control cells (C). Sebum production of pairs of glands is normalized relative to that of untreated glands, and the results are fitted with exponential decay curves. The bar heights represent the 50% inhibitory dosages (mg/ml) at which 50% reduction of the untreated control lipid incorporation was obtained. Values represent means ± SD of three independent experiments carried out in triplicates.
