Introduction: Argan oil is a well-known cosmeceutical that is commercially available. It is traditionally used for the treatment of acne and skin inflammation among others. The objective of this study was to assess the anti-proliferative and antibacterial activities of argan oil and a crude saponin extract from the argan tree (Argania spinosa (L.) Skeels) that is endemic to Morocco. Materials and Methods: The anti-proliferative activity of argan oil and the crude saponin extract was assessed by the 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium- 5-carboxanilide (XTT) assay on A431; HaCat; HeLa; MCF-7 and UCT-Mel 1 cells. The antibacterial activity was evaluated by the broth microdilution method against two species of bacteria: Cutibacterium acnes and Prevotella intermedia. Results: The results of this study indicated that the argan oil sample did not inhibit the cell growth of the specified cell lines up to 1000μg/ml, while the crude saponin extract had low anti-proliferative activity. The minimal inhibitory concentration (MIC) values for both the argan oil and the crude saponin extract were found to be 500μg/ml against Cutibacterium acnes. No antibacterial activity from the argan oil or the crude saponin extract was evident against Prevotella intermedia up to a concentration of 12.5mg/ml. Conclusion: The results of this study indicated that argan oil and the crude saponin extract might have direct inhibitory effects on the growth and proliferation of Cutibacterium acnes. This finding supports the use argan oil as a treatment for acne vulgaris.

Objective:Butea monosperma, Barleria prionitis, Casuarina equisetifolia, Dalbergia sissoo, and Lagenaria siceraria are reported to possess anti-acne, anti-infl ammatory, anti-ulcer, and wound healing activity. The present work is aimed at evaluating the wound healing potential of these plant materials in acne vulgaris. Methodology: Individual gel formulations containing extracts of the above mentioned drugs and their polyherbal gels were evaluated by excision and incision wound model (in vivo) in Sprague Dawley rats. Results: The individual gel formulations showed signifi cant reduction in wound size when compared with the untreated group. The rates of wound closure after the application of the gels were compared with the untreated wounds. The polyherbal formulation containing all the extracts was found to be more benefi cial when compared to remaining treated groups. Healing under scab and formation of normal epithelial cells were better than other individual formulations. As well as vascular changes, cellular infi ltration, and necrosis were found less. Conclusion: From the results, it may be concluded that the plants are endowed with signifi cant wound healing activity, thereby justifying its traditional medicinal use in acne vulgaris as a separate entity and in combination. Chemical components such as tannins, fl avonoids, saponins, and alkaloids present in the extracts can be responsible for the foresaid activity.
